BaNU generates adaptable naive Bayesian networks from a database. The generated knowledge can be exported as Notation3 rules. Another feature is the ability to link with ILP systems such as Toplog and Aleph to find premises for the adaptable NBN's.

BabyTALK is to add another brick in the wall of natural languages learning. The baby needs to structure a corpus of texts when his tutor points and talks about a particular part of the corpus. The baby is also to describe any selected part of the corpus.

Java/XML toolkit for research using Bayesian networks and other graphical models of probability (exact and approximate inference, structure learning, etc.)

Bayesian Network tools in Java (BNJ) is an open-source suite of software tools for research and development using graphical models of probability. It is published by the Kansas State University Laboratory for Knowledge Discovery in Databases (KDD).

Belief merging aims at combining several pieces of (possibly inconsistent) information coming from different sources. The goal is to produce a single consistent set of information, trying to keep the most of the information of the sources. A belief merging operator is the responsible for making the belief merging. With this tool you can compare the ΔΣ, ΔGMax and the Δps (PS-Merge) operators.

Belief revision is a central topic in knowledge representation and reasoning. It consists in incorporating a new belief, changing as few as possible of the original beliefs while preserving consistency. Revision always considers new evidence as a better belief. Such new evidence is usually represented in the form of a propositional formula which must be preserved after the revision. Here, the Δps (PS-Merge) belief merging operator is extended in order to consider constraints, and this extension is used as a strategy for belief revision. The new evidence is treated as a constraint so the extended merging operator can obtain the revised belief base.

A fast and flexible explorer for various types of fractals

Uses MathSciNet to search for bibtex references. The matching references can then be edited and added to a local file. For information on how to use this software please consult the wiki. Requires a MathSciNet subscription.

Boolean Expression Solver is a command-line utility that generates a truth table for a given Boolean expression.

Applications for mobile phones with Java installed (KVM MIPS 2), which functions as a calculator to solve basic problems offered to scientists of computing.

===== Project moved to https://github.com/fpetitjean/Chordalysis ===== Log-linear analysis is the statistical method used to capture multi-way relationships between variables. However, due to its exponential nature, previous approaches did not allow scale-up to more than a dozen variables. We present here Chordalysis, a log-linear analysis method for big data. Chordalysis exploits recent discoveries in graph theory by representing complex models as compositions of triangular structures, also known as chordal graphs. Chordalysis makes it possible to discover the structure of datasets with thousands of variables on a standard desktop computer. Associated papers at ICDM 2013, ICDM 2014 and SDM 2015 can be found at http://www.francois-petitjean.com/Research/ YourKit is supporting Chordalysis open source project with its full-featured Java Profiler.

Clados is a java package that implements a multivector in a Clifford Algebra. Algebras (over real numbers) with any signatures may be used. A calculator and associated documentation is also included to help users learn how things work.

Goal of Coatie3D project is the development of a 3D graph drawer/ viewer. The purpose of graph drawing is the identification of a pleasant layout for a given graph.

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm

A java program for exploring cubic fractals, similar to the Mandelbrot set but exhibiting a higher level of dynamical complexity. CubicBrowser provides the ability to explore the 4D Cubic Locus (and associated Julia sets) by viewing arbitrary 2D slices.

Implementation of various mathematical curves that define themselves over a set of control points. The API is written in Java. The curves supported are: Bezier, B-Spline, Cardinal Spline, Catmull-Rom Spline, Lagrange, Natural Cubic Spline, and NURBS.

Distributed Java Fractal Generator. DJFractals can computes fractals in arbitrary precision using any CPU available from high performance multi-processors clusters of computers to grid of JavaCards and even at the same time.

Depth Explorer is a visual interactive tool for learning about Statistical Data Depth and evaluating depth measures.

An EDM calibration baseline is used to derive specific instrument errors of the electronic distance measurement (EDM) unit of a total station. EDMFit is a simple adjustment tool to estimate the EDM calibration parameters (addition constant and/or scale parameter). The adjustment process is according to ISO 17123-4. The parameters are checked for significance, to avoid an overestimation. Based on two classical hypothesis testing, EDMFit provides a reliable outlier detection. For uncertainties budgeting, EDMFit makes use of Monte-Carlo simulations and supports different distribution function: - Uniform distribution, - Triangular distribution and - Gaussian (normal) distribution. For refractive index determination, the application supports the following models: - Barrel and Sears (1939), - Edlen (1953, 1966), - Owens (1967), - IAG (1999) and - Ciddor (1996, 2002). The results of the adjustment are reported in a template-based and valid HTML5/CSS3 report.
