Bayesian Decomposition:
Bayesian Decomposition is a pattern recognition algorithm which uses Bayesian statistics and Markov chain Monte Carlo sampling to determine the physically significant basis vectors for a data set. Mathematically a matrix factorization is performed, creating a matrix defining the basis vectors (patterns) and the distributions of the patterns within the data. The Bayesian statistics allow for incorporation of prior knowledge through the encoding of correlations between data points. The software is presently available in a form for spectroscopy, a form for studying exponential distributions, and a form which encodes no correlations between data points.

This extension allows the user to define expected coregulated sets of genes, such as linked by a transcription factor (TF), which BD will use as prior information.
