CE {0,1} d=1 You will begin by estimating the parameters of . P(Y) . p(X[d]|Y = c) Vce {0, 1}, de {1, 2 } from the labeled dataset, using Maximum Likelihood Estimation (MLE). Note that, p(Y) is a Bernoulli distribution; p(X[1][Y = c) is a Bernoulli distribution of X[1]; p(X[2]|Y = c) is a Gaussian distribution of X [2]. (a) Prior distributions [2 points] What is p(Y = 1)? The answer is a real number. (b) Conditional distributions [5 points] What is p(X[1] = 1/Y = 0)? What is p(X [1] = 1/Y = 1)
