Allowing Growing Dimensional Binary Outcomes via the Multivariate Probit Indian Buffet Process

F Stolf, DB Dunson - arXiv preprint arXiv:2402.13384, 2024 - arxiv.org
There is a rich literature on infinite latent feature models, with much of the focus being on the
Indian Buffet Process (IBP). The current literature focuses on the case in which latent …

Spatially-dependent Indian Buffet Processes

S Sugasawa, D Mochihashi - arXiv preprint arXiv:2409.01943, 2024 - arxiv.org
We develop a new stochastic process called spatially-dependent Indian buffet processes
(SIBP) for spatially correlated binary matrices and propose general spatial factor models for …
