The spin interaction terms s is j thus be-come s is j = (hs ii+ s i)(hs ji+ s j) = hs ...
WebStarting with a carefully formulated Dirichlet process (DP) mixture model, we derive a generalized product partition model (GPPM) in which the parti- tion process is predictor-dependent. The GPPM generalizes DP clustering to relax the exchangeability assumption through the incorporation of predictors, resulting in a generalized Polya urn scheme.
