Software

Implementations of machine learning algorithms.

• - Sean Eddy's lab, present profile hidden Markov models for biological sequence analysis, a tool used to build HMMs from multiple alignments, and calculate e-scores.
  
• - Supports several inference algorithms and learning algorithms. Allows simulation of static and dynamic networks, including HMMs, IOHMMs, and Kalman filters.

• - Commercial Securities Modeler that uses artificial neural networks and genetic algorithms for customizable prediction
  
• - Tools for learning dependency networks or Bayesian networks from data. [Free]
  
• - Machine learning library for Observable Operator Models (OOMs) suitable for time-series and sequence data classification and prediction. OOMs are similar but more powerful than HMMs. [C++, BSD license]

• - On this page an imlementation of Hidden Markov Models and an application to part-of-speech tagging. Also available a multivariate hypothesis testing software for Gaussian Data and TRUEVIZ: A groundtruth/metadata Editing and Visualizing Toolkit for OCR.
  
• - A program implementing several memory-based learning techniques. These learners store representation of the training set explicitly, and classifies new cases by extrapolation from the most similar stored cases. Free for educational or non-commercial resea
  
• - A library of C++ classes for Bayesian filtering. From the Australian Centre for Field Robotics. [C++, MIT license]
  
• - An architecture for planning and learning. [Free]
  
• - A general purpose library for Bayesian filtering. [C++, LGPL license]
  
• - Takes a database of cases described by a combination of real and discrete valued attributes, and automatically finds the natural classes in that data. It can be seen as a Naive Bayes classifier where the class node is hidden. [Free]
  
• - A learning computer player for the light cycles game in Tron
  
• - Hidden Markov Models software library from the Center of Applied Informatics, Cologne. Includes algorithms such as Viterbi, Baum-Welch, and Forward-Backward. [C, GPL license]
