Greedy learning of binary latent trees
WebGreedy Learning of Binary Latent Trees. Inferring latent structures from observations helps to model and possibly also understand underlying data generating processes. A rich class of latent structures is the latent trees, i.e., tree-structured distributions involving latent variables where the visible variables are leaves.
