Traduki is a free machine translation system written in C/Lua. It works by creating an interlinguistic representation of text in Lua tables, the representation being somewhat modelled on the generative grammar of Noam Chomsky. Traduki aims to feature support for less common languages.
Charlemagne is a versatile genetic programming application. It includes a commandline client and an interactive console mode. It is written in Python and Lisp, and is user extensible to some degree in both languages. It features built-in input-output mapping support and provides the ability to define complex fitness calculations in Lisp or Python.
The Kolmogorov project provides tools for machine perception and tutorials for machine learning, machine perception, and statistics. It supports fast face detection in images and information on Hidden Markov models, Gabor filters, Multivariate Logistic Regression, and Stochastic Differential Equations. It includes MPISearch, a library for detecting objects in images very quickly (real-time in some cases).
The Robot Auto Racing Simulator (RARS) consists of a simulation of the physics of cars racing on a track, a graphic display of the race, and a separate control program (robot "driver") for each car. The goal of the game is to implement such a control program in order to compete against other programmers. An official formula one season is held every year.
Kalyp is a fantasy-based roguelike game written in Java. Its design is based on traditions set by popular roguelike games, especially Nethack. It is single player and runs in a text terminal. The project focuses mostly on the Artificial Intelligence engine for the non-player characters. Most of the game design will be done in scripting, as the core engine written in Java will handle user interface, rulesets, basic actions, and try to hold it all together.
Maximum entropy is a powerful method for constructing statistical models of classification tasks, such as part-of-speech tagging in Natural Language Processing. The Quipu Maximum Entropy Package is a Java implementation of the maximum entropy framework. It allows you to train, evaluate, and use maxent models.
