graphicalmodellearning.jl's Introduction

GraphicalModelLearning.jl

Dev:

Algorithms for Learning Graphical Models

Installation

In julia run,

Pkg.clone("https://github.com/lanl-ansi/GraphicalModelLearning.jl.git")

Quick Start

Try the following commands in julia,

using GraphicalModelLearning

model = FactorGraph([0.0 0.1 0.2; 0.1 0.0 0.3; 0.2 0.3 0.0])
samples = sample(model, 100000)
learned = learn(samples)

err = abs.(convert(Array{Float64,2}, model) - learned)

Note that the first invocation of learn will be slow as the dependent libraries are compiled. Subsequent calls will be fast.
