Hierarchical pachinko allocation
Pachinko allocation was first described by Wei Li and Andrew McCallum in 2006. The idea was extended with hierarchical Pachinko allocation by Li, McCallum, and David Mimno in 2007. In 2007, McCallum and his colleagues proposed a nonparametric Bayesian prior for PAM based on a variant of the hierarchical … Ver mais In machine learning and natural language processing, the pachinko allocation model (PAM) is a topic model.
