Boltzmann machine tools

Python tools for analysing Boltzmann machine / Ising spin models. Includes functions for calculating exact moments of small Boltzmann machine models, exact maximum-likelihood gradient based training and various MCMC sampler implementations.

Installation

Requires NumPy, SciPy and CVXPY.

If Cython is installed, the Cython extension modules can be build from the Cython .pyx source files using

python setup.py build_ext -use-cython

If Cython is not installed, the generated C source of the modules is also included and running setup.py without the -use-cython option will use the C source instead.

The following additional optional arguments can also be used with setup.py:

  -debug            Export GDB debug information when compiling.
  -use-gcc-opts     Use GCC compiler optimisations for quicker but less safe
                    mathematical operations.
  -use-cython-opts  Add extra Cython compile directives for quicker but less
                    safe array access. Requires -use-cython to be set to have
                    an effect.
  -use-openmp       Compiles with OpenMP support.
