A Zero-Inflated Latent Dirichlet Allocation Model for Microbiome Studies [PDF]
Frontiers in Genetics, 2021 The human microbiome consists of a community of microbes in varying abundances and is shown to be associated with many diseases. An important first step in many microbiome studies is to identify possible distinct microbial communities in a given data set

A Spectral Algorithm for Latent Dirichlet Allocation [PDF]
Algorithmica, 2014 The problem of topic modeling can be seen as a generalization of the clustering problem, in that it posits that observations are generated due to multiple latent factors (e.g., the words in each document are generated as a mixture of several active topics, as opposed to just one).
