A probabilistic population code based on neural samples

NeurIPS 2018oral

Sensory processing is often characterized as implementing probabilistic inference: networks of neurons compute posterior beliefs over unobserved causes given the sensory inputs. How these beliefs are computed and represented by neural responses is much-debated (Fiser et al. 2010, Pouget et al. 2013)…

Weighted Theta Functions and Embeddings with Applications to Max-Cut, Clustering and Summarization

NeurIPS 2015poster

We introduce a unifying generalization of the Lovász theta function, and the associated geometric embedding, for graphs with weights on both nodes and edges. We show how it can be computed exactly by semidefinite programming, and how to approximate it using SVM computations. We show how the theta fu…
