We propose a novel method based on Bayesian inference of maximum entropy models for detecting and modeling cell assemblies from population activity. The family of statistical models considered is a generalization of the Ising model, with high-order interactions organized in a community-like manner. We call them minimally complex spin models, in reference to their low information theoretic complexity. During this talk, I will explain the method and demonstrate its ability in identifying groups (or “communities’’) of highly correlated variables in artificial data generated from benchmark models with high-order interactions. We will then apply the approach to identify cell assemblies in publicly available data recorded from hundreds of retinal ganglion cells. Finally, we will compare our results with the assemblies obtained from the standard statistical approach based on Principal Component Analysis and discuss some of the advantages offered by our approach.
