Machine Learning 1 TU Berlin, WiSe 2020/21 Expectation-Maximization In this programming exercise we will apply the Expectation-Maximization method to estimate the parameters of the latent variable model presented in the theoretical part. The analysis will be performed on one dimension of the Boston Housing dataset, where input values are integers between 0 and 24. In

Machine Learning 1 TU Berlin, WiSe 2020/21 Training a Restricted Boltzmann Machine In this exercise, we implement and train an RBM to model the distribution of MNIST digits 3. The following code loads some libraries, extracts the MNIST digits 3, and converts them to binary vectors. In [1]: import matplotlib %matplotlib inline from matplotlib import
