The question is:
Since P(w1) = P(w2) = P(w3), the posterior probabilities P(wi|x); i = 1; 2; 3; are determined by the class-conditional densities p(x|wi); i = 1; 2; 3. Hence, we first estimate/train p(x|wi); i = 1; 2; 3 with MLE approach. Assume that p(x|wi)~N(MUi,SIGMAi)
Use the fi rst 1000 samples of each category to estimate p(x|wi) and plot the resulting class-conditional densities.
My question:
should i write a matlab code? how am i supposed to estimate p(x|wi)?
Thank you.
