Choose a topicznMultinomial(θ).
Each document is a mixture of topics, where Mult(theta) is a the document's distribution over topics. The generative model assumes each word within a document corresponds to a topic (drawn from the multinomial above) which in turn encodes a multinomial distribution over words.
Process models, on the other hand, provide specification ofinternal structure, mechanism, and information flow
predictive processing is a process model that is suggested (or constrained) by the FEP.
during the backward pass, feedback connectionsare used in concert with forward connections to dynamically invert the forward transformation,thereby enabling errors to flow backward
