  1. 0:00Thank you to Kashi San.
  2. 0:02And hi guys, my name is Shinsuke. So,
  3. 0:04let's uh get back to the more like
  4. 0:08serious part.
  5. 0:10Uh which is the about the final
  6. 0:12assignment.
  7. 0:14Okay, so let's get started. So, first uh
  8. 0:18uh let me introduce myself. My name is
  9. 0:20Shinsuke Komiya.
  10. 0:22And yeah, I'm I'm a postdoc researcher
  11. 0:25at Mazola and I'm uh the lead uh
  12. 0:28developer of this year's educational
  13. 0:29materials
  14. 0:31together with Aki. And my research
  15. 0:33interest uh lies in the intersection of
  16. 0:35dynamical systems and machine learning.
  17. 0:37And my hobby is listening to uh
  18. 0:39practically any kinds of music.
  19. 0:43And about the uh uh
  20. 0:45instructions of final assignment, uh
  21. 0:48what I'm going to be covering today is
  22. 0:51uh shown here.
  23. 0:52Which is one, the overview of final
  24. 0:54assignment. And after that, uh I'm going
  25. 0:56to be talking about uh uh the general
  26. 0:59thing about uh what does a good business
  27. 1:02proposal look like.
  28. 1:04And and which is followed by how does it
  29. 1:07apply to your uh final assignment. And
  30. 1:10after that, I'm going to be covering
  31. 1:11frequently asked questions. And after
  32. 1:14that, I'm going to be having uh a few
  33. 1:15minutes of of Q&A section.
  34. 1:19Okay, let's uh start from the overview
  35. 1:21of final assignment.
  36. 1:24So, as Aki mentioned at the beginning,
  37. 1:27the final assignment is a required to uh
  38. 1:31realize any state of completion. So,
  39. 1:34please uh please submit a final
  40. 1:36assignment. Don't forget that.
  41. 1:38Uh you need to pass uh the final
  42. 1:40assignment. Okay?
  43. 1:43And you uh as for the final assignment,
  44. 1:45you're required to make presentation
  45. 1:47slides uh to propose your business
  46. 1:49strategy using provided assets.
  47. 1:52And deadline is written here, November
  48. 1:5428th, 11:00 a.m. UTC. And please submit
  49. 1:57your presentation slides together with
  50. 1:59the novel files that you use for your
  51. 2:01analysis, and your list of references.
  52. 2:06Okay, so the
  53. 2:07next part, how to get started. So, this
  54. 2:10is pretty much the same
  55. 2:12as Aki explained at the beginning
  56. 2:15of the
  57. 2:16competition.
  58. 2:17So, what you have to do is that please
  59. 2:20go
  60. 2:21is to go to the shared folder,
  61. 2:23and please go to the 05 final
  62. 2:26assignment.
  63. 2:27And there you're going to be seeing a
  64. 2:29folder named final assignment,
  65. 2:32and together with the tutorial PDF.
  66. 2:35And first you have to download the final
  67. 2:37assignment folder to your local PC,
  68. 2:40and it should be downloaded it should be
  69. 2:42downloaded as a zip file.
  70. 2:46And please unzip the downloaded zip file
  71. 2:49maybe in your local environment, then
  72. 2:52upload the final assignment folder to
  73. 2:53your My Drive. So, I'm going to skip the
  74. 2:56real, you know,
  75. 2:58the hands-on doing this, but yeah, I
  76. 3:01think you should
  77. 3:02do this.
  78. 3:04Pretty much the same as you did in the
  79. 3:06competition.
  80. 3:07And you can
  81. 3:08always use your local environment if you
  82. 3:12don't find the online Google Colab
  83. 3:14environment uncomfortable.
  84. 3:18And okay, so if you
  85. 3:22go to the final assignment folder and
  86. 3:23unzip it and upload it to the My Drive,
  87. 3:26this pretty much looks like this, I
  88. 3:28guess.
  89. 3:30And this contains four elements, each of
  90. 3:33which
  91. 3:34is like this. So, first you're going to
  92. 3:37be seeing telecom folder,
  93. 3:39which contains all the data you'll be
  94. 3:41using.
  95. 3:42A second,
  96. 3:44some document,
  97. 3:46which is additional description of the
  98. 3:48data.
  99. 3:49And third, you're going to be seeing
  100. 3:51readme docs. This is the the very
  101. 3:54important instructions of the final
  102. 3:56assignment.
  103. 3:57I think.
  104. 3:59And after that you're going to be
  105. 4:03seeing that the tutorial IP Y and B,
  106. 4:05which is the data analysis example.
  107. 4:07So, first, maybe you should take a look
  108. 4:11at the read me docs. This This is
  109. 4:14which is the really important
  110. 4:16instruction.
  111. 4:18So, if you hit this
  112. 4:20document,
  113. 4:22you're most likely seeing this
  114. 4:26section.
  115. 4:27And the
  116. 4:29scenario and objective
  117. 4:31section, it goes like, "You're a new
  118. 4:33associate at an IT consulting firm. The
  119. 4:36sales team has just secured a POC
  120. 4:39project from a company. The company has
  121. 4:41a large data set, but has limited
  122. 4:43in-house expertise to use them for
  123. 4:45business.
  124. 4:46Your job is to run EDA and build at
  125. 4:49least one machine learning model on the
  126. 4:51data set.
  127. 4:52And from evidence of market analysis,
  128. 4:54you need to define the client core
  129. 4:56business problem. Then, you'll be create
  130. 4:58a data-driven business proposal with
  131. 5:00quantified impact."
  132. 5:02Okay, so this is basically what you
  133. 5:03should do in a final assignment. So,
  134. 5:05maybe I can end my
  135. 5:08explanation now.
  136. 5:10Yeah, which
  137. 5:12is just a joke. So, yeah. So,
  138. 5:15yeah, so if you're done with the final
  139. 5:17assignment,
  140. 5:18made all the presentation and notebook,
  141. 5:20how to submit your final assignment?
  142. 5:24So, yeah, it's as always, you do this
  143. 5:27through the Omni campus. So, please log
  144. 5:29in to the Omni campus, you're going to
  145. 5:30be finding
  146. 5:32uh the report name final assignment,
  147. 5:33okay?
  148. 5:35And I think you should be seeing this
  149. 5:37already
  150. 5:38because it's already open.
  151. 5:40Sorry. And
  152. 5:43by clicking this, you'll find these
  153. 5:46things.
  154. 5:47And you're going to be putting in a
  155. 5:49title, list of references, Jupiter
  156. 5:51notebook together with the slide, which
  157. 5:54is the most important thing.
  158. 5:56And this is accompanied by uh
  159. 6:00questionnaires. I think I set up four or
  160. 6:03five questions, I guess.
  161. 6:05And this is about the surveys of AI
  162. 6:07usage. And please answer it and honestly
  163. 6:11because we we we're not be uh, this just
  164. 6:14a pure survey and this doesn't affect
  165. 6:16your score at all.
  166. 6:18In in a good way or in a bad way.
  167. 6:22Okay, so far for the uh, bureaucratic
  168. 6:25things about the final assignment. So,
  169. 6:27I'm going to moving on to what does a
  170. 6:29good business proposal look like uh,
  171. 6:31section.
  172. 6:33So,
  173. 6:34uh, this is what you saw in your readme
  174. 6:36docs.
  175. 6:38And you're required to um, create a
  176. 6:42business proposal based on the given
  177. 6:43data
  178. 6:45and uh, identify the client's business
  179. 6:47problem and present a solution.
  180. 6:50So, at first, um, I think uh, we should
  181. 6:52cover we should go through what a good
  182. 6:55business proposal looks like uh, in the
  183. 6:57first place.
  184. 7:00And this is how the business proposal
  185. 7:04uh, usually uh, looks like. Uh, this is
  186. 7:06the a typical workflow we uh, always um,
  187. 7:10do.
  188. 7:12And this is pretty much complicated,
  189. 7:14isn't it? So, uh,
  190. 7:16and it's a bit overwhelming. But, no
  191. 7:18worries. I'm going to be explaining uh,
  192. 7:20this step by step, okay?
  193. 7:25So, although the workflow looked a
  194. 7:27little bit overwhelming and complicated
  195. 7:30um, this uh, should be similar up to
  196. 7:33three key points.
  197. 7:35Which is
  198. 7:36uh, first um, a good business proposal
  199. 7:39should specify an important issue worth
  200. 7:41solving.
  201. 7:43And second, it includes a hypothesis to
  202. 7:45solve uh, that issue.
  203. 7:48And third, this is verifiable.
  204. 7:50Okay?
  205. 7:51So, I'm going to be explaining one by
  206. 7:53one starting uh, with the specifying an
  207. 7:56important issue worth solving.
  208. 7:59So, this amounts um, to here, the very
  209. 8:02first part of this workflow.
  210. 8:07And let's imagine a guy, a client, who
  211. 8:10came up to you who comes up to up to you
  212. 8:13and saying, "Our product A is suffering
  213. 8:15from sluggish sales, although it has
  214. 8:17more functions, more settings, more
  215. 8:20fabulous, you know, functions and better
  216. 8:22performance than its competitors. What
  217. 8:24are we going to do about this?"
  218. 8:27So, what are you
  219. 8:29going to do about this?
  220. 8:31So, I'm going to take like 5 seconds, so
  221. 8:32please think about the answer.
  222. 8:37Okay, so you might answer like this,
  223. 8:40"The performance of the product is
  224. 8:42already great, so the marketing strategy
  225. 8:44seems to have a problem. Let's start
  226. 8:46from running more web advertising."
  227. 8:48Is it really good? Do you think it's
  228. 8:50really good?
  229. 8:52So,
  230. 8:53I
  231. 8:54it's kind of
  232. 8:56um
  233. 8:57naive answer, I I would say. So, it's
  234. 8:59like you're jumping So, this guy
  235. 9:02is jumping onto the very, you know, easy
  236. 9:05way to solve this problem.
  237. 9:07So, uh before that, you have to stop and
  238. 9:11think and ask yourself
  239. 9:13if you're referring to the real issue
  240. 9:17here.
  241. 9:19So, to do that, let's
  242. 9:22focus on the three things that this
  243. 9:26client is saying.
  244. 9:29So, this guy is mentioning about the
  245. 9:32sluggish sales.
  246. 9:33But, about the sluggish sales, you have
  247. 9:35to
  248. 9:36if you if you talk if you want to talk
  249. 9:38about the sluggish sales,
  250. 9:40you have to be
  251. 9:41caring about how big the market might
  252. 9:44be.
  253. 9:45And you might ask yourself, "Do other
  254. 9:48products also face sluggish sales?"
  255. 9:50So, if the market is is shrinking
  256. 9:53itself,
  257. 9:54in that case, however, it might happen
  258. 9:58that no matter how your your product is
  259. 10:02is fantastic,
  260. 10:03you might get sluggish sales.
  261. 10:06So, to know that, you have to uh some
  262. 10:09background analysis, a background
  263. 10:11search.
  264. 10:13And the client was saying about more
  265. 10:15functions.
  266. 10:16And if you talk about more functions, it
  267. 10:19it usually it often happens that um um
  268. 10:22more functions
  269. 10:24uh turned out unnecessary for the
  270. 10:26customers.
  271. 10:28So, you might want to ask, are customers
  272. 10:29happy with more uh functions?
  273. 10:32The product having more functions?
  274. 10:34Or uh isn't it worsening its uh
  275. 10:38product's operability?
  276. 10:41So, to check that, you might want to run
  277. 10:44some customer survey.
  278. 10:47And the clients was talking about better
  279. 10:49performance. So, this is a little bit
  280. 10:51like a more functions, but is really
  281. 10:52necessary? You might want to ask, is it
  282. 10:54neces- is it really necessary to have
  283. 10:56better performance?
  284. 10:58Or is this a better performance um
  285. 11:00making the price higher so that that the
  286. 11:03customers um um
  287. 11:05are uh um might hesitate buying that.
  288. 11:11So, to uh know get more information
  289. 11:13about this, um
  290. 11:19I think yeah, I'm I'm making a mistake,
  291. 11:21but um yeah, so um
  292. 11:23maybe um
  293. 11:25yeah, maybe you you can run a customer
  294. 11:27survey or or maybe um uh the another
  295. 11:30product with a less um um
  296. 11:33performance might cover up this um
  297. 11:35product.
  298. 11:38So, uh what I want to say here is that
  299. 11:41you must find and focus on the core
  300. 11:44issue
  301. 11:45uh behind uh what the client saying.
  302. 11:48Okay?
  303. 11:50And collecting background information
  304. 11:52and some quantitative analysis, like uh
  305. 11:55some very easy, like first step EDA,
  306. 11:58will help you find an issue uh worth
  307. 12:00working on.
  308. 12:01So, it's like uh this is uh this usually
  309. 12:04happens, and this um um
  310. 12:07finding the core finding the real issue
  311. 12:10um
  312. 12:11uh of
  313. 12:13in in any situation is the most
  314. 12:15difficult part.
  315. 12:17And this
  316. 12:19um
  317. 12:19applies to research. So, in in research,
  318. 12:22you have to make a good question, which
  319. 12:24is the most difficult part.
  320. 12:26And it that is that quite as as I can
  321. 12:29mention at the beginning, this is quite
  322. 12:31the same as the business setting, I
  323. 12:32guess.
  324. 12:33And um Einstein
  325. 12:37um
  326. 12:37uh in the past said that the formulation
  327. 12:40problem is often more essential than its
  328. 12:42solution, which may be merely a matter
  329. 12:44of mathematical experiment and skill.
  330. 12:46So,
  331. 12:47uh the the the the formulation of a
  332. 12:49problem is the most uh important part.
  333. 12:52And the solution uh comes just next to
  334. 12:56uh setting the right um question.
  335. 12:59So, yeah, the the this always happens
  336. 13:03that people uh always tend to, you know,
  337. 13:05more difficult technical, like
  338. 13:07mathematics technical, you know, um
  339. 13:09things technical mathematical, you know,
  340. 13:12uh machine learning models, whatever,
  341. 13:14but that's is just um um step to take
  342. 13:18to achieve the goal. And the goal is
  343. 13:20more important, of course.
  344. 13:22Okay?
  345. 13:24Okay, so uh next. So, a good business
  346. 13:26proposal um should include a hypothesis
  347. 13:29to solve the issue. So, this comes to
  348. 13:32the step two and four
  349. 13:34uh in the workflow I first showed.
  350. 13:38And once you find a good issue
  351. 13:41to uh work on, you should settle your
  352. 13:42hypothesis on that issue.
  353. 13:45So, a hypothesis, as you um you may
  354. 13:48know,
  355. 13:49is a tentative answer to your issue that
  356. 13:52seems the closest to the correct answer.
  357. 13:56Why do you have to uh build a
  358. 13:57hypothesis?
  359. 13:59Without focusing on the hypothesis, you
  360. 14:01can't take action or make the decisions.
  361. 14:04So, uh usually, if you face a client and
  362. 14:09a client having a problem,
  363. 14:11um once after, you know,
  364. 14:14even after finding a good issue, good uh
  365. 14:17starting point
  366. 14:19to uh start your workflow um over.
  367. 14:24Um that there
  368. 14:26uh almost always are um a bunch of
  369. 14:29problems you should be you should you
  370. 14:31have to solve. So, there are many many
  371. 14:33problems you have to solve if if you
  372. 14:36even if even after the focusing the
  373. 14:38issue, okay?
  374. 14:41And um
  375. 14:43I I
  376. 14:45I I think you can't
  377. 14:47you basically can't answer every issue
  378. 14:50by yourself, okay?
  379. 14:53And you you don't you even don't have to
  380. 14:55do that, okay? So, you what you have to
  381. 14:57do is that um you might be at a loss
  382. 15:00with the uh list of the problems you're
  383. 15:02going to be seeing.
  384. 15:04But in order to, you know, get the
  385. 15:07things um proceed,
  386. 15:10you don't have to answer one by one all
  387. 15:11the problems, but you have to focus
  388. 15:14on the problem you have to uh
  389. 15:17dealing be dealing with.
  390. 15:20And to do that, hypothesis uh works a
  391. 15:22lot, okay? And the lack of hypothesis uh
  392. 15:25paralyze people, especially when they're
  393. 15:27given only data. So, this happened this
  394. 15:29actually happened to me myself
  395. 15:32um until quite recently.
  396. 15:34And um I was kind of a person who like,
  397. 15:37you know, uh getting all the result of
  398. 15:39all the uh data or the experiment result
  399. 15:42whatever.
  400. 15:44Uh I uh what I would do was that I would
  401. 15:47you know, do the the do the most, you
  402. 15:50know, detailed and scrutinized
  403. 15:52experiment that to search what's
  404. 15:55happening behind this data.
  405. 15:58And um
  406. 15:59after that, I'm going to be getting
  407. 16:01nothing, okay? So, the most meticulous
  408. 16:04most like, you know,
  409. 16:05um
  410. 16:07um detailed experiments without having a
  411. 16:10hypothesis result, you know, having some
  412. 16:13um um having a like clear goal
  413. 16:16to first go to,
  414. 16:18will get you nothing, okay?
  415. 16:20So, you have first have to um uh build a
  416. 16:23question you have to answer.
  417. 16:26And you have to uh concretize your
  418. 16:28question so that you you get the uh uh
  419. 16:31uh the first tentative goal
  420. 16:34you would want to um hit, okay?
  421. 16:38And on this initial hypothesis what one
  422. 16:41important thing is that this initial
  423. 16:42hypothesis can be wrong and but that you
  424. 16:45need to uh uh
  425. 16:47run the uh like, you know, recursive
  426. 16:49step
  427. 16:51to correct the hypothesis on after um
  428. 16:54um doing some experiments or something.
  429. 16:58So, how can you make a good hypothesis?
  430. 17:02This is where your data analysis skills
  431. 17:04come in and this is where the you what
  432. 17:08you learned in this lectures come in.
  433. 17:12And um to uh make a good hypothesis it
  434. 17:15should be um
  435. 17:17uh built on the quantitative analysis
  436. 17:19and insights based on it, okay?
  437. 17:23And in in the real business settings,
  438. 17:25you can also uh collect real opinion
  439. 17:27from the people involved uh
  440. 17:29uh
  441. 17:30yeah.
  442. 17:32And about the uh
  443. 17:35uh building a hypothesis uh sorry, the
  444. 17:37EDA um you you you do in in making good
  445. 17:41hypothesis.
  446. 17:43So, actually EDA uh turns up
  447. 17:47here and here, two steps uh between uh
  448. 17:51the uh problem hypothesis creation and
  449. 17:53proposal uh before the uh proposal idea
  450. 17:56section. So, there I would say
  451. 18:00are two types of EDA.
  452. 18:02The first of which is to determine your
  453. 18:05issue and initial hypothesis.
  454. 18:08Okay, so the first uh EDA is a little
  455. 18:11bit of uh you know, um
  456. 18:13to grasp an overview and insights of
  457. 18:17what's happening uh behind the data
  458. 18:20and it can be explorative but not too
  459. 18:22haphazard.
  460. 18:23Okay? And after uh maybe finding the
  461. 18:26issue and building your hypothesis
  462. 18:29and after that you have to focus on your
  463. 18:32hypothesis and run another ED another
  464. 18:35type of EDA which is more focused and to
  465. 18:39to deepen and evaluate your hypothesis.
  466. 18:43Okay?
  467. 18:44And they should try to answer initial
  468. 18:46hypothesis as I mentioned. And this
  469. 18:50would be more
  470. 18:51concrete.
  471. 18:52Maybe with machine learning models,
  472. 18:54extra boost, random forest, whatever
  473. 18:58to
  474. 18:59answer your first hypothesis.
  475. 19:03And lastly the good business proposal
  476. 19:06should be verifiable.
  477. 19:08So this comes after proposal
  478. 19:12sorry after building hypothesis
  479. 19:15and last step and this arrow that goes
  480. 19:19from five to two. Okay?
  481. 19:24So
  482. 19:26the specify your core issue and building
  483. 19:28your hypothesis and proposal it is not
  484. 19:31the end. So you need to verify and
  485. 19:33validate your proposal
  486. 19:34over and over again. Okay?
  487. 19:37So maybe you need to answer questions as
  488. 19:40after building a hypothesis you should
  489. 19:43answer
  490. 19:44such questions as what the expected
  491. 19:47profit or the projected profit of your
  492. 19:49proposal.
  493. 19:51So
  494. 19:52you might think about a bunch of
  495. 19:54hypothesis and maybe you should take the
  496. 19:57one with the most
  497. 19:59projected profit. So that's
  498. 20:02important.
  499. 20:04So what's the limitation? So no proposal
  500. 20:07we don't expect you know perfect
  501. 20:09proposal without any flaws.
  502. 20:11Okay no proposal on the earth is
  503. 20:13perfect. So
  504. 20:14so you're you're it's it's quite okay to
  505. 20:17have you know weak points or limitations
  506. 20:20but you should be aware of that. And
  507. 20:22hopefully you should be dealing with
  508. 20:25with your verification
  509. 20:28cycle limitations
  510. 20:30as as far as you can, okay?
  511. 20:35And how do you continuously test and
  512. 20:37verify your proposal? So, how do you
  513. 20:38reflect feedback from the customers?
  514. 20:40This is another important
  515. 20:42um
  516. 20:43things to do to run the recursive step.
  517. 20:46Okay?
  518. 20:47So, um
  519. 20:49this is another kind of, you know,
  520. 20:52workflow, but things
  521. 20:54usually goes like this.
  522. 20:57And first, you find your issue, as I
  523. 20:59mentioned, and you build a hypothesis
  524. 21:02for this issue first, and do the
  525. 21:04verification. And this always should be
  526. 21:06repetitive in that
  527. 21:10looking after this result of this
  528. 21:13verification and validation, whatever.
  529. 21:15You have to renew, update your
  530. 21:18hypothesis
  531. 21:19after this, okay? And you have to this
  532. 21:22is the
  533. 21:23this is quite just the same as the
  534. 21:25competition, as Aki explained earlier.
  535. 21:29This is a recursive step you're going to
  536. 21:30be seeing. So, this is pretty much the
  537. 21:33same as the research.
  538. 21:35And this is pretty much the same as the
  539. 21:37business kind of
  540. 21:40workflow, I guess.
  541. 21:43And you might What you might get is like
  542. 21:45a meta circle in which you're going to
  543. 21:48be
  544. 21:49renewing the issue
  545. 21:52So, after running through many over and
  546. 21:54over again this cycle, you will be
  547. 21:58noticing another important issue that
  548. 22:01you have been missed or or others
  549. 22:04have missed.
  550. 22:05So, this is the very, you know, novel
  551. 22:08and great issue you find.
  552. 22:12And then
  553. 22:13yeah, this repetitive circle circle
  554. 22:17might have the outer step to to renew
  555. 22:20the issue itself.
  556. 22:22Okay.
  557. 22:24And how does it apply our
  558. 22:26finance assignment? So, let's go to the
  559. 22:31maybe I'm running out of a little bit of
  560. 22:33time, but let's go to the tutorial ipynb
  561. 22:37and
  562. 22:39which looks like
  563. 22:41this.
  564. 22:46Okay, if you go to the shared folder
  565. 22:49and if you hit the finance assignment
  566. 22:52you're going to be seeing tutorial ipynb
  567. 22:55which pretty much
  568. 22:56looks like this.
  569. 22:58And
  570. 23:00what it's doing is that
  571. 23:03um
  572. 23:06it's first downloading sorry
  573. 23:10it's downloading the data
  574. 23:12and doing some very basic EDAs.
  575. 23:15And in that there the creator is
  576. 23:20uh
  577. 23:21leading a hypothesis uh which I we're
  578. 23:24going to be looking at later.
  579. 23:28And
  580. 23:30yes, so this is a database that the
  581. 23:33database sorry the data set we're going
  582. 23:35to be using in a finance assignment is
  583. 23:37the telecom data set
  584. 23:39which is about the
  585. 23:41the the list of bunch of clients
  586. 23:44and who's turned
  587. 23:46who's
  588. 23:48continued their contract. So, trading is
  589. 23:51like you know
  590. 23:53the churning churning is the correct
  591. 23:56word. It is stop
  592. 23:58the churning is to to you know giving up
  593. 24:01the contract
  594. 24:03with the
  595. 24:04the carrier telecommunication company
  596. 24:07carrier, okay?
  597. 24:08And so what you are seeing here is that
  598. 24:12you're basically looking at the basic uh
  599. 24:16data what does what this data looks like
  600. 24:20first
  601. 24:21and you're doing in section three you're
  602. 24:23doing some a very basic
  603. 24:26EDAs
  604. 24:27where your um uh
  605. 24:31depicting the distributions of state and
  606. 24:33churned
  607. 24:35um people distribution.
  608. 24:38And um
  609. 24:40and it's closer look here. So,
  610. 24:44we're going to be looking at the uh
  611. 24:47uh
  612. 24:48the equipment age distribution.
  613. 24:50And in this um
  614. 24:53histogram,
  615. 24:55you can see that the the churned
  616. 24:57distribution is shifted to the right
  617. 25:00um compared to the state distribution,
  618. 25:03which means um
  619. 25:05the churners have longer ownership of uh
  620. 25:11the device. Okay? So, this is very
  621. 25:13natural because, you know, if you if you
  622. 25:15think your your cell phone or whatever
  623. 25:17gets old, you might want to, you know,
  624. 25:19change that. Okay?
  625. 25:22And yeah.
  626. 25:25Somebody else is uh continuous, but uh
  627. 25:29yeah, let's get back to Yeah, I'm only
  628. 25:32having a glance at the notebook, and
  629. 25:34let's get back to the upper notation.
  630. 25:36And so, yeah, how today's instructions
  631. 25:39apply to your final assignment. The most
  632. 25:41straightforward issue maybe is as you
  633. 25:43saw in the uh uh in the notebook.
  634. 25:47So, uh the the very straightforward
  635. 25:50issue is the how to increase the profit
  636. 25:53by decrease the churn rate. Okay? So,
  637. 25:55the churn rate is so was, you know, uh
  638. 25:58uh distributed and was shown in the
  639. 26:00notebook. And this might be the most
  640. 26:03straightforward and and important thing
  641. 26:05to to, you know, uh
  642. 26:07have at the first
  643. 26:09uh glance.
  644. 26:11And there can be, however, other choices
  645. 26:12of issues to approach. So, you have to
  646. 26:15um
  647. 26:16So, you you can, you know, propose your
  648. 26:17issue, another issue in your uh uh
  649. 26:21final assignment, but it has to be
  650. 26:23coupled with EDN background knowledge
  651. 26:25and and a something
  652. 26:27After EDA, you you gain some insights on
  653. 26:30what's happening, and you can uh build
  654. 26:32your hypothesis.
  655. 26:34Okay? And the hypothesis then the
  656. 26:37example notebook
  657. 26:39built was do longer equipment ages
  658. 26:42increase the generation.
  659. 26:44And you can explain this hypothesis
  660. 26:48if if it looks persuasive by adding more
  661. 26:50focused EDAs.
  662. 26:52Okay?
  663. 26:53And to make your proposal verifiable in
  664. 26:56final assignment, you can receive the
  665. 26:58real feedback of your proposal, but at
  666. 27:00least you should show what makes your
  667. 27:04proposal legitimate, the project that
  668. 27:06profit, the estimated profit of the
  669. 27:08proposal,
  670. 27:10and the way to continuously test,
  671. 27:11verify, and update the proposal. Okay?
  672. 27:14With the limitation.
  673. 27:18And the about the yeah, so
  674. 27:22the good thing is that we're going to be
  675. 27:24publishing
  676. 27:26the past outstanding student example
  677. 27:28slides
  678. 27:29in the
  679. 27:31uh uh
  680. 27:32shared folder.
  681. 27:34So although the you can't copy and paste
  682. 27:36of course, so this is the thing the data
  683. 27:38set this example is dealing with the
  684. 27:41different from the one we're using right
  685. 27:43now. So yeah, but but this pretty much
  686. 27:48would be the good example, good goal for
  687. 27:51you to get to. Okay?
  688. 27:54So frequently asked questions.
  689. 27:57So first question, am I going to fail
  690. 27:59final assignment even if I submit my
  691. 28:00report if the quality is too bad? Yes,
  692. 28:03we have our own criteria for grading
  693. 28:05final assignment. So just submitting
  694. 28:07your final assignment is not enough.
  695. 28:09Okay? So please make you know good final
  696. 28:12assignment.
  697. 28:13There should be so many submissions. Do
  698. 28:15you use AI for grading?
  699. 28:17We're afraid we can't answer anything
  700. 28:18about the concrete process of grading.
  701. 28:20So we're sorry, but we can't say
  702. 28:23we're using AI or not, but at least we
  703. 28:26can say that
  704. 28:27there are so many graders, okay? So many
  705. 28:29graders in our team. So that's uh,
  706. 28:32as long as I can say.
  707. 28:35We want to know the grading rubrics. I
  708. 28:37think I I found this question in already
  709. 28:41posted in the Q&A dashboard. And we were
  710. 28:44afraid that we're not planning to
  711. 28:46release a rubrics, okay? Sorry about
  712. 28:48that.
  713. 28:49But, in fact,
  714. 28:52the requirement section in Redmi docs
  715. 28:56tells you pretty much about how your
  716. 28:58report is going to be graded. So, we
  717. 29:00strongly recommend you to read it
  718. 29:03carefully, entirely,
  719. 29:05and follow the requirements. So,
  720. 29:07yes, all I can say is
  721. 29:10yeah, please read
  722. 29:11the uh,
  723. 29:14thing. Read what what I written in this
  724. 29:16requirement section, okay?
  725. 29:19Can I use AI for my final assignment?
  726. 29:21Yes, we actually recommend the use of
  727. 29:23AI, which accelerate the hypothesis
  728. 29:25evaluation circle
  729. 29:27cycle. Any AI usage will not affect your
  730. 29:29score, but please
  731. 29:32share your URL or output chat history in
  732. 29:35the
  733. 29:37the
  734. 29:38when when you submit your final
  735. 29:40assignment, okay?
  736. 29:42And additional notes about your AI not
  737. 29:44usage, so using AI doesn't necessarily
  738. 29:47decrease the workload, okay? So,
  739. 29:50nowadays, you know, students
  740. 29:53happy with AI because, you know,
  741. 29:56you can just
  742. 29:57maybe you like
  743. 29:59I predict that the you might be, you
  744. 30:02know, putting on all the data set, all
  745. 30:05the materials, maybe this material, this
  746. 30:07very material,
  747. 30:09and put in the cloud code or ChatGPT or
  748. 30:11whatever, and output your slide, and
  749. 30:14that's done. That that's never done,
  750. 30:15okay? And AI helps you dramatically in
  751. 30:18providing methodologies, implementing
  752. 30:20code, and visualizing. But, AI still
  753. 30:23have problems in specifying core issues
  754. 30:26with big picture or building nice
  755. 30:28hypotheses or making representation easy
  756. 30:31for human to understand, okay?
  757. 30:34So, I think these two points are pretty
  758. 30:37much answered in the previous
  759. 30:40instructions, but the last one last one
  760. 30:42is a very big problem
  761. 30:44we have to deal with. Okay, so um
  762. 30:47AI tend to lack, you know, comprehensive
  763. 30:50and broader perspective with which
  764. 30:53um
  765. 30:54which makes human beings
  766. 30:58easier to, you know, understand any kind
  767. 31:01of problem.
  768. 31:03And they they often tend to be
  769. 31:06too particular about the insignificant
  770. 31:08very insignificant very detailed very
  771. 31:11meticulous very unnecessary things. So,
  772. 31:16I don't recommend, you know,
  773. 31:18in you know, one rally
  774. 31:21you put all the materials you need in
  775. 31:23the final assignment and
  776. 31:25uh you know,
  777. 31:27press an enter key and yeah, that's
  778. 31:29done. I don't recommend that, okay? At
  779. 31:32least you have to, you know, iterate the
  780. 31:34process
  781. 31:35um I don't know about five times um at
  782. 31:38that at least, I don't know, maybe 10 or
  783. 31:41maybe 20 or 50 times
  784. 31:44to get the uh the ideal one that you
  785. 31:47that you really want.
  786. 31:49Okay? So, it's a
  787. 31:51recursive iterative stuff.
  788. 31:54Uh can you extend the deadline? So, I
  789. 31:56have my school exam. So, this is the one
  790. 31:58of the most frequently asked questions
  791. 32:01after when it comes to, you know,
  792. 32:05if if if it's near the deadline. No, we
  793. 32:08are afraid we will never make a deadline
  794. 32:10extension, okay? So, please make sure
  795. 32:12you can submit before deadline. No
  796. 32:14school schedule, technical difficulties,
  797. 32:16other situations, other explanations, no
  798. 32:19other excuses can be your excuse, okay?
  799. 32:21So, please submit your report with
  800. 32:23plenty time to spare.
  801. 32:25Can I make my final assignment in my own
  802. 32:26language? Please don't do that, okay?
  803. 32:28Please use English
  804. 32:30in your presentation.
  805. 32:33Other important notes include final
  806. 32:34assignment should be in presentation
  807. 32:36slides
  808. 32:37equals or less than 15 pages, not in
  809. 32:40document. Make it readable to those who
  810. 32:42first read your report. So, it's
  811. 32:45pretty much related to what I said in
  812. 32:47the AI usage
  813. 32:48disclaimer. But, the
  814. 32:50LLM tend to use obscure wordings, no
  815. 32:53explained jargons. Please don't do that.
  816. 32:57Please um
  817. 32:58make it human-friendly
  818. 33:01um report, okay?
  819. 33:05And put figures in your presentation
  820. 33:07slides, not just in your notebook. So,
  821. 33:09we see some reports saying that
  822. 33:12there are no figures
  823. 33:15in the presentation, but
  824. 33:17instead please look at the notebook
  825. 33:19output. So,
  826. 33:21we we actually are looking at your
  827. 33:24notebook, but the evaluation is but
  828. 33:27mostly for mostly based on the
  829. 33:30presentation slide itself. So, please
  830. 33:32put figures in the presentation, okay?
  831. 33:34Don't change your theme. Now, this is
  832. 33:36another important thing. So,
  833. 33:38we see some participants
  834. 33:41um dealing with their own problem, their
  835. 33:43own like, you know, problem in their
  836. 33:45country. So, so no matter how, you know,
  837. 33:49good
  838. 33:51these presentations are, we we have to
  839. 33:53we must fail them, okay? So, don't do
  840. 33:56that.
  841. 33:57Again, we will never make a data
  842. 33:58expansion. So, this is so important I to
  843. 34:02say twice.
  844. 34:03But, submit with plenty time to spare,
  845. 34:06okay? And so, yes, that's
  846. 34:09it from my side. And maybe I should
  847. 34:13yes, go to the Q&A.
  848. 34:17Maybe four or five questions.
  849. 34:21What are the final assignment
  850. 34:22competition requirement including topic
  851. 34:24choice, format, grading, rank is
  852. 34:25deadline, eligibility for credit? As I
  853. 34:28mentioned, the reworks on web been not
  854. 34:30open. Sorry about that. But, again,
  855. 34:33please read the requirements.
  856. 34:35Okay, requirements in your tutorial.
  857. 34:38Sorry, read me.
  858. 34:41How will the final assignment
  859. 34:42competitive evaluated? Sorry, so read
  860. 34:44the requirements section, okay?
  861. 34:48How can I submit the final assignment
  862. 34:49correctly in five minutes square
  863. 34:50competition? Submit the final Okay, so
  864. 34:53this is what I explained. So this is via
  865. 34:56the Omni campus and you can think you
  866. 34:58can find
  867. 34:59the
  868. 35:01uh
  869. 35:01page from which you can submit your
  870. 35:03final assignment.
  871. 35:05How will competition submission
  872. 35:06evaluated and ranked? So this is I think
  873. 35:09Yeah, so all these things about
  874. 35:11evaluation,
  875. 35:12we apologize, but we will not saying
  876. 35:15anything about the concrete rubrics or
  877. 35:17complete evaluation criteria. But
  878. 35:21But one thing this is really important,
  879. 35:23so I'm saying again and again, but
  880. 35:24please read your instruction. Please
  881. 35:27read your requirements, okay?
  882. 35:30One word by one word, okay?
  883. 35:32And this is so important. So this this
  884. 35:34as long as I can say is that this the
  885. 35:36requirements section is pretty much
  886. 35:38pretty much related to the evaluation
  887. 35:41rubrics. So this is
  888. 35:43as long as I can say.
  889. 35:46How will the competition be evaluated
  890. 35:47and ranked? So this is about the
  891. 35:48competition. How do you
  892. 35:54Maybe a questions a few more questions
  893. 35:58final assignment working determine the
  894. 36:00features of my rules.
  895. 36:02Issue of competition.
  896. 36:05I think they're answered by Akia, I
  897. 36:07guess. I was wondering if there are any
  898. 36:09guideline using
  899. 36:12Okay, so I'm I'm going to be answering
  900. 36:15this.
  901. 36:19I was wondering if there are any
  902. 36:21guidelines for using AI tools such as
  903. 36:23ChatGPT cloud as learning resources. For
  904. 36:26example, if you use them to clarify
  905. 36:28concepts, understand methods of
  906. 36:29discussing oops
  907. 36:31Where did it go? Discussing possible
  908. 36:33approaches to improve our models without
  909. 36:36asking them to generate code or build
  910. 36:38the model for us. How should these
  911. 36:40interactions be documented? If we use
  912. 36:42multiple conversations throughout the
  913. 36:44project, should we include all of them
  914. 36:47or only the director related to our
  915. 36:48work? I'm also interested in
  916. 36:50understanding how these guidelines help
  917. 36:52ensure fair evaluation for everyone.
  918. 36:54Distinguish
  919. 36:55between A using AI as a learning
  920. 36:57resource and having AI generate the code
  921. 36:59or develop
  922. 37:00the model on our behalf. Okay, so um
  923. 37:04yes, um I would say um
  924. 37:08yes, please share um
  925. 37:10as many AI chat any records you made uh
  926. 37:14with your AI as possible.
  927. 37:17So, uh it shouldn't be like
  928. 37:19it shouldn't be like um
  929. 37:21um
  930. 37:23yeah, you should be yeah,
  931. 37:26it has to be like on URL, I guess.
  932. 37:29to um to share your record, but um
  933. 37:32please like um include all all the
  934. 37:35conversation you have with your AI,
  935. 37:37okay? And um
  936. 37:42How should these interactions be
  937. 37:43documented? So,
  938. 37:46yes, so um honestly, you can make um
  939. 37:49your AI build or write your code by your
  940. 37:52um instead of yourself.
  941. 37:54And um
  942. 37:55but we we're focusing in in at least in
  943. 37:58the final assignment, we we're focusing
  944. 38:01on the final derivative, okay? Final PDF
  945. 38:04you're going to be making.
  946. 38:06So, um
  947. 38:09yes, so the uh whether you're you made
  948. 38:12your code by yourself or
  949. 38:14or if you let the AI do that, uh
  950. 38:17wouldn't matter as long as uh the final
  951. 38:20derivative is the same, okay? So, we're
  952. 38:23looking purely looking at the at a PDF,
  953. 38:25the slides presentation you make.
  954. 38:28And yeah, so I hope that
  955. 38:31uh answered your question.
  956. 38:34Um
  957. 38:35okay, maybe
  958. 38:37uh
  959. 38:38time is up for me. Sorry, I couldn't
  960. 38:40answer so many so many questions, but I
  961. 38:44hope these
  962. 38:46um
  963. 38:47frequently asked questions pretty much
  964. 38:49answered your
  965. 38:50questions.
  966. 38:52Okay, and
  967. 38:56back to the slides.
  968. 38:58Yes, we have attendance survey but no
  969. 39:01homework today, okay?
  970. 39:03And homework for today is I think this
  971. 39:07is pretty much mistaken but yeah, so
  972. 39:09this this is the same as
  973. 39:12always, okay?
  974. 39:15Okay, so that's it for the
  975. 39:19today. So, thank you very much everyone
  976. 39:22and I hope you guys do your best in the
  977. 39:24competition of final assignment.
  978. 39:26Bye.
