The PILGRIM project relies on and encapsulates the ProBT platform, developped by ProbaYes. ProBT allows to model, learn and make inference in Bayesian networks and PILGRIM reuses many of its classes defining basic concepts in probabilistic programming, while extending its capabilities in terms of Bayesian networks structure learning and in terms of relational datasets support.
The ProBT library is distributed with the different PILGRIM projects as a binary file, and is the property of ProbaYes. Using ProBT separately for other purposes is subject to the ProBT licence agreement.

NMF with KL-divergence (Insight Journal 152)
Some classes also use the work of Pathak et al. in the Insight Journal paper number 152, available under the Creative Commons 3.0 licence with Attribution. This work has been updated by replacing VXL library matrix types and computations by Boost UBLAS ones. In addition, this work has been used as a starting point to implement also other NMF methods.
