Starting with a carefully formulated Dirichlet process (DP) mixture model, we derive a generalized product partition model (GPPM) in which the partition process is predictor-dependent. The GPPM generalizes DP clustering to relax the exchangeability assumption through the incorporation of...

Certain species in nature have evolved characteristics that provide protection from predators. Batesian mimicry is a system that describes a model/mimic relationship, in which a palatable organism phenotypically resembles an unpalatable organism. The effectiveness of the mimicry system may...
