Published in Towards Data Science·PinnedMember-onlyLatent Variables & Expectation Maximization AlgorithmBayesian Approach to Machine Learning — ‘Latent’, originated from Latin which means being hidden. Probably you have all known about latent heat, which is the heat energy required for phase transformation keeping the temperature constant. So we observe a change, but the reason behind it is apparently hidden. The motivation for Latent Variable Model (LVM) is…Machine Learning14 min readMachine Learning14 min read
