 Description:
JProGraM is an opensource Java library which can be used for learning the following probabilistic models from data: Bayesian networks, Markov random fields, hybrid random fields, probabilistic decision trees, dependency networks, Gaussian mixture models, and Parzen windows. Along with learning algorithms, some simple inference methods are implemented by JProGraM. Principal components analysis and (to some extent) data clustering are also supported.

Version Changelog Date 13.2 JProGraM 13.2  CHANGE LOG
Release date: February 13, 2012
New features:  Support for Fiedler random graphs/random field models for largescale networks (ninofreno.graph.fiedler package);  Various bugfixes and enhancements (especially in the ninofreno.graph and ninofreno.math package).
February 13, 2013, 20:29:38 12.8 JProGraM 12.8  CHANGE LOG
Release date: August , 2012
This is a major update of JProGraM. Most notable additions include:  A basic implementation of multilayer feedforward neural networks (ninofreno.ann package);  ErdősRényi, WattsStrogatz, and BarabásiAlbert random network models (ninofreno.graph.gen package);  Markov and higherorder exponential random graph models for networks, using kstar and ktriangle statistics (ninofreno.graph.ergm package);  Subgraph sampling algorithms for undirected networks (random walk, random jump, snowball, inducent and incident subgraph sampler), along with methods for computing graph spectra (ninofreno.graph package);  Area under the ROC curve calculator (ninofreno.data package);  Lots of bugfixes and enhancements.
JProGraM 10.5  CHANGE LOG
Release date: May 30, 2010
 Support for continuous graphical models has been added: Gaussian, nonparanormal, and kernelbased Markov random fields, hybrid random fields and Bayes nets are now implemented;  Routines for kernelbased conditional density estimation (NadarayaWatson estimators) have been implemented, with support for scalable dualtree recursion techniques (used in the bandwidth selection routines);  Methods for generating arbitrarily shaped multivariate density functions and for sampling datasets from them have been added;  Independent Component Analysis is now also supported (by wrapping the FastICA library);  Gaussian mixture models have been greatly improved by adding support for expectationmaximization, fixing some numerical stability issues and differentiating a simpler version with diagonal covariance matrices from a more complex version with full covariance matrices;  Other minor features have been added, and a number of corrections have been introduced.
Note that the Gaussian and nonparanormal Markov random fields relying on the graphical lasso technique require a working R distribution (http://www.rproject.org/) to be installed on your system, including in particular the external glasso package (http://wwwstat.stanford.edu/~tibs/glasso/). Provided that R and the glasso package are correctly installed, the relevant JProGraM routines are able to exploit the R installation without any manual intervention. This means that users of the JProGraM library can sinmply call the routines executing the graphical lasso within their Java code without the need to manipulate any R code. (This has been tested successfully on several Linux distributions, but not on Windows or Mac OS X).
JProGraM 9.1  CHANGE LOG
