This repo describes the NEO estimator described in the paper NEO: Non Equilibrium Sampling on the orbit of a deterministic transform published at NeurIPS 2021 and available https://papers.nips.cc/paper/2021/file/8dd291cbea8f231982db0fb1716dfc55-Paper.pdf.

Three notebooks describe typical experiments of the main paper.

• Mix_gaussian, the normalizing constant estimation on a mixture of Gaussian distributions
• Sampler the sampling of a mixture of Gaussian distributions or on Funnel distribution.
• Experiments_colab the training of VAE.

Mainly uses pytorch, pyro-ppl. Later tensorboard
