2. (10 points) Recall that in the Question 3 of homework 1, we implemented a two-class Gaussian discriminant. In this question, answer the following about k-class Gaussian discriminant: (a) Given mean Hi, covariance matrix ; and prior P(C) of the i-th class, write down the discriminant function gi (b) Briefly explain how to predict the label of a new data point with discriminant functions. 2.
