  author={Dan Geiger and Christopher Meek},
We provide a classification of graphical mod­ els according to their representation as sub­ families of exponential families. Undirected graphical models with no hidden variables are linear exponential families (LEFs), directed acyclic graphical models and chain graphs with no hidden variables, including Bayesian networks with several families of local dis­ tributions, are curved exponential families (CEFs) and graphical models with hidden variables are stratified exponential families (SEFs… CONTINUE READING
