Probabilistic graphical models, to a certain extent, serve such a purpose. We explore a new graphical model (probabilistic multi-graph decomposition) to incorporate multiple networks and inference hidden block state variables, by which we identify local cliques among the graphs. Probabilistic graphical models (PGMs) are a rich framework for encoding probability distributions over complex domains: joint (multivariate) distributions over large numbers of random variables that interact with each other. A standard training method for probablistic graphical models often involves using Expectation Maximization (EM) for Maximum a Posteriori (MAP) training, approaximate inference and approximate decoding.

Larry Wasserman – Fall 2014. The probability of a word is assumed to be dependent only on the words preceding it This probability model for word sequences is as accurate as the earlier whole-word-sequence model, in theory It has the advantage that the probabilities of words are applied left to right –this is perfect for speech recognition. Many of the problems in artificial intelligence, statistics, computer systems, computer vision, natural language processing, and computational biology, among many other fields, can be viewed as the search for a coherent global conclusion from local information.
