README.md

Efficient Variational Inference for Gaussian Process Regression Networks package.

This package implements the two variational inference methods for GPRNs of Nguyen and Bonilla [1].

Author:

Trung V. Nguyen (trung.ngvan@gmail.com)

Last update: 03/04/2013

Main Content

  1. meanfield/mf_train.m : train a GPRN model with mean-field inference method
  2. meanfield/mf_predict.m : predict using a trained mean-field model obtained from mf_train.m
  3. npv/npv_train.m : train a GPRN model with npv inference method
  4. npv/npv_predict.m : predict using a trained npv model obtained from npv_predict.m
  5. demo.m : A script demonstrating the use of mean-field and npv on a toy dataset.

Dependencies

This code uses two external libraries: the gpml package [2] and the code in [3] with modifications by Trung V. Nguyen to handle high-dimensional datasets.
