Approximate sampling and estimation of partition functions using neural networks

1 code implementation21 Sep 2022 George T. Cantwell

We consider the closely related problems of sampling from a distribution known up to a normalizing constant, and estimating said normalizing constant.

Belief propagation for permutations, rankings, and partial orders

no code implementations1 Oct 2021 George T. Cantwell, Cristopher Moore

Many datasets give partial information about an ordering or ranking by indicating which team won a game, which item a user prefers, or who infected whom.

Belief propagation for networks with loops

no code implementations23 Sep 2020 Alec Kirkley, George T. Cantwell, M. E. J. Newman

Belief propagation is a widely used message passing method for the solution of probabilistic models on networks such as epidemic models, spin models, and Bayesian graphical models, but it suffers from the serious shortcoming that it works poorly in the common case of networks that contain short loops.

Bayesian inference of network structure from unreliable data

1 code implementation7 Aug 2020 Jean-Gabriel Young, George T. Cantwell, M. E. J. Newman

Most empirical studies of complex networks do not return direct, error-free measurements of network structure.

Recovering the past states of growing trees

2 code implementations10 Oct 2019 George T. Cantwell, Guillaume St-Onge, Jean-Gabriel Young

In principle one can reconstruct the past states of a growing network from only its current state.

Improved mutual information measure for classification and community detection

no code implementations29 Jul 2019 M. E. J. Newman, George T. Cantwell, Jean Gabriel Young

The information theoretic quantity known as mutual information finds wide use in classification and community detection analyses to compare two classifications of the same set of objects into groups.

Mixing patterns and individual differences in networks

1 code implementation2 Oct 2018 George T. Cantwell, M. E. J. Newman

We study mixing patterns in networks, meaning the propensity for nodes of different kinds to connect to one another.
