Nonparametric Bayesian Factor Analysis for Dynamic Count Matrices
Ayan Acharya, Joydeep Ghosh, Mingyuan Zhou
A gamma process dynamic Poisson factor analysis model is proposed to factorize a dynamic count matrix, whose columns are sequentially observed count vectors. The model builds a nov…
The Poisson Gamma Belief Network
Mingyuan Zhou, Yulai Cong, Bo Chen
To infer a multilayer representation of high-dimensional count vectors, we propose the Poisson gamma belief network (PGBN) that factorizes each of its layers into the product of a…
Gamma Belief Networks
Mingyuan Zhou, Yulai Cong, Bo Chen
To infer multilayer deep representations of high-dimensional discrete and nonnegative real vectors, we propose an augmentable gamma belief network (GBN) that factorizes each of its…
Infinite Edge Partition Models for Overlapping Community Detection and Link Prediction
Mingyuan Zhou
A hierarchical gamma process infinite edge partition model is proposed to factorize the binary adjacency matrix of an unweighted undirected relational network under a Bernoulli-Poi…
