EECE5644 Introduction to Machine Learning and Pattern Recognition HW3

EECE5644 Introduction to Machine Learning and Pattern Recognition HW3 Question 1 (60%) In this exercise, you will train many multilayer perceptrons (MLPs) to approximate class label posteriors. The MLPs will be trained using maximum likelihood parameter estimation (or equiva- lently, minimum average cross-entropy loss). You will then use the trained models to approximate a maximum

EECE5644 Introduction to Machine Learning and Pattern Recognition Assignment 2

EECE5644 Introduction to Machine Learning and Pattern Recognition Assignment 2 Question 1 (50%) The probability density function (pdf) for a 2-dimensional real-valued random vector X is as follows: p(x) = p(L = 0)p(x|L = 0)+ p(L = 1)p(x|L = 1). Here L is the true class label that indicates which class-conditioned pdf generates the data.
