Posterior Contraction Rates of the Phylogenetic Indian Buffet Processes

31 Jul 2013Mengjie ChenChao GaoHongyu Zhao

By expressing prior distributions as general stochastic processes, nonparametric Bayesian methods provide a flexible way to incorporate prior knowledge and constrain the latent structure in statistical inference. The Indian buffet process (IBP) is such an example that can be used to define a prior distribution on infinite binary features, where the exchangeability among subjects is assumed... (read more)
