Unsupervised representation learning with recognition-parametrised probabilistic models

2 code implementations13 Sep 2022 William I. Walker, Hugo Soulat, Changmin Yu, Maneesh Sahani

We introduce a new approach to probabilistic unsupervised learning based on the recognition-parametrised model (RPM): a normalised semi-parametric hypothesis class for joint distributions over observed and latent variables.

Structured Recognition for Generative Models with Explaining Away

1 code implementation12 Sep 2022 Changmin Yu, Hugo Soulat, Neil Burgess, Maneesh Sahani

A key goal of unsupervised learning is to go beyond density estimation and sample generation to reveal the structure inherent within observed data.

Probabilistic Tensor Decomposition of Neural Population Spiking Activity

1 code implementation NeurIPS 2021 Hugo Soulat, Sepiedeh Keshavarzi, Troy Margrie, Maneesh Sahani

The firing of neural populations is coordinated across cells, in time, and across experimentalconditions or repeated experimental trials; and so a full understanding of the computationalsignificance of neural responses must be based on a separation of these different contributions tostructured activity. Tensor decomposition is an approach to untangling the influence of multiple factors in data that iscommon in many fields.
