85. 4:15is 433.
86. 4:19So, this is the lead current leader
87. 4:21board.
88. 4:23Our leader Farhana1,
89. 4:27okay.
90. 4:28So, next quiz.
91. 4:32Which of these train test score
92. 4:34indicates that the model is over fitting
93. 4:37on the training data?
94. 4:41So, again, the score is calculated based
95. 4:44on how fast you can answer as well.
96. 4:525 seconds left.
97. 4:553 2 1 boom.
98. 4:59So, the correct answer is 80% uh {slash}
99. 5:0250%.
100. 5:03All right, so let's see our leader
101. 5:05board.
102. 5:07Still Oh, okay. Elda came first.
103. 5:12All right, so next question.
104. 5:16Question number three, what is printed?
105. 5:345 4 3
106. 5:392 1
107. 5:43So, from over 500 participant
108. 5:47choose the correct answer. So, let's see
109. 5:50the leader board. Yalakti 190.
110. 5:53All right. Next question, question
111. 5:56number four, I guess.
112. 5:58You have altitude and temperature of
113. 6:004200 weather stations in Japan. Which
114. 6:03plot best shows their relationship?
115. 6:17All right, 5 seconds left. 4 3 2 1 0.
116. 6:24So, the correct answer is a scatter
117. 6:26plot.
118. 6:27So, more than 700 participants choose
119. 6:31the correct answer. So, let's see the
120. 6:33leaderboard.
121. 6:35So, leader has just changed to IB the
122. 6:39saint.
123. 6:40So, he got I don't know. They got 3,431
124. 6:44points. So, let's move on to the next.
125. 6:51These are the prediction error for two
126. 6:53different
127. 6:54model. Which statement about MAE and MSE
128. 6:58is true?
129. 7:143 2 1 boom.
130. 7:18Oh, I think it seems like this is a
131. 7:20tough one.
132. 7:21So, the correct answer is both
133. 7:26Let's see.
134. 7:28Let's see. Let's see.
135. 7:30Both has equal MAE but A has higher MSE.
136. 7:34All right. So, let's see leaderboard.
137. 7:37Oh, leader has just changed to Hannah E
138. 7:40Jacob. All right. So, question number
139. 7:44six.
140. 7:45Only 1% of Japan train trips are
141. 7:48delayed. What is the recall for delays
142. 7:51for other model that always
143. 7:54predicts on time?
144. 7:58Oh, this seems like this is a tricky
145. 8:00question again.
146. 8:0310 seconds left.
147. 8:085 4 3 2 1 boom
148. 8:14Okay, this is also tough one.
149. 8:18So the the correct answer is 0%.
150. 8:21So let's see our leaderboard.
151. 8:25Still Hana E Jacob got the first place.
152. 8:29All right.
153. 8:30So question number seven.
154. 8:35Oh, it's hard to read.
155. 8:37But this is the quiz number seven.
156. 8:44It's getting I think the harder and
157. 8:46harder.
158. 8:47>> [music]
159. 8:50>> 10 seconds left.
160. 8:555 4 3 2 1 0
161. 9:02Oh, okay. It seems like it's
162. 9:04all right. So more than 400 participant

170. 9:25Quiz number eight. How many of Japan's
171. 9:27prefecture have no coastline? This is
172. 9:30the I think one of the difficult
173. 9:32[laughter]

175. 9:37So again, uh the score is calculated
176. 9:40based on how fast you can answer as
177. 9:41well. So if you don't know the answer, I
178. 9:44think I would recommend you to do uh as
179. 9:46quickly as possible. 3 2 1 0
180. 9:51Okay. Okay. We have kind of smarter uh
181. 9:54participant as well. Uh so more than uh
182. 9:56700 participant choose the correct

192. 10:35Okay.
193. 10:36Okay, so uh 287 uh participants who got
