Ising Model Statistical Test Implementation
This is an implementation of the paper "Concentration of Multilinear Functions of the Ising Model with Applications to Network Data". This is a submission for Nurture.ai's Global NIPS Paper Implementation Challenge.
The implementation can be found in this notebook.
Summary of results
The notebook contains code that
- Generates samples of Ising lattices with nearest-neighbor interaction under zero magnetization using MCMC
- Generates samples that depart from an Ising model in the high-temperature limit, with the departure parameterized by a variable τ
- Performs a hypothesis test on these samples using a statistic introduced in the paper, where the null hypothesis is that the sample is an Ising lattice in the high-temperature limit
- Plots the percentage of successful rejections of the null hypothesis is plotted against τ (see plot below)
