Implementation in Julia of a Restricted Boltzmann Machine (RBM) on top of the Ising model sampled with the Metropolis algorithm. (Based on the 2016 paper by Torlai and Melko[1].)

Running

In a Julia prompt in this directory, run

julia> import Pkg
julia> Pkg.activate(".")
julia> Pkg.instantiate()

This installs dependencies. To train the RBM and produce the files kldiv_1D.pdf and pdf_1D.pdf, run

julia> include("run/1D.jl")
julia> IsingBoltzmann1DRun.main()

The parameters of the RBM and the training can be tweaked using the CONFIG variable found in run/1D.jl.

It works now!

I used to have a blurb here about how it doesn't work, but it does work now; for the sake of posterity, that blurb can be found here: README.broken.md
