(2) (1 pt) Suppose we have data about 5 people shown below. phase 1 name Magda Valerie Kumar Octavia Dorete level 1 5 2 6 6 trials 10 20 15 30 5 -1 1 1 -1 Suppose we want to model the level of each person using the following constant model: f(x) = 0. What is that minimizes the average L2 loss? O (a) 3.5 O (b) 4.0 O(C) 4.5 O (d) 5.0 O (e) 5.5 (3) (1 pt) (Continued) What is ê that minimizes the average Li loss? O (a) 3.5 O (b) 4.0 O (C) 4.5 O (d) 5.0 0 (0) 5.5 (4) (2 pt) (Continued) What is ên that minimizes the following Huber loss (a = 2). 1 ) y - <a La(0,y) = 360-032 ( |a(lu – 01 - otherwise O (a) ên = 4.0 O (b) 4.0 < B < 5.0 O (c) â = 5.0 O (d) 5.0 <ên < 6.0 (5) (3 pt) Consider the following loss function. Given a sample 11,...In, which value of 6 minimizes the average loss? S (6 – x) L(0,2) = 14(x – 0) θΣΥ <r (b) 25th percentile O (c) 50th percentile O (d) 75th percentile (a) 20th percentile O (e) 80th percentile
