  • WEKA

    Free Mac Windows Linux Website

    Weka is a collection of machine learning algorithms for data mining tasks; with its own GUI.

    (The application is named after a flightless bird of New Zealand that is very inquisitive.)

    The algorithms can either be applied directly to a dataset or called from your own Java code.

    Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes.

  • Vega-Lite

    Free Web Self-Hosted Website

    Vega-Lite provides a higher-level grammar for visual analysis, comparable to ggplot or Tableau, that generates complete Vega specifications. Vega-Lite specifications consist of simple mappings of variables in a data set to visual encoding channels such as x, y, color, and size. These mappings are then translated into detailed visualization specifications in the form of Vega specification language. Vega-Lite produces default values for visualization components (e.g., scales, axes, and legends) in the output Small Vega Visualization Grammar iconVega Visualization Grammar specification using a rule-based approach, but users can explicit specify these properties to override default values.

  • RGraph

    Free Personal Mac Windows Linux Website

    RGraph is a HTML5 canvas graph library. It uses features that became available in HTML5 (specifically, the CANVAS tag) to produce a wide variety of graph types: bar chart, bi-polar chart (also known as an age frequency chart), donut chart, funnel chart, gantt chart, horizontal bar chart, LED display, line graph, meter, odometer, pie chart, progress bar, rose chart, scatter graph and traditional radar chart.

  • Julia

    Free Mac Windows Linux Website

    Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library. The library, largely written in Julia itself, also integrates mature, best-of-breed C and Fortran libraries for linear algebra, random number generation, signal processing, and string processing.

    In addition, the Julia developer community is contributing a number of external packages through Julia’s built-in package manager at a rapid pace. IJulia, a collaboration between the IPython and Julia communities, provides a powerful browser-based graphical notebook interface to Julia.

    It is based on Small libuv iconlibuv

  • ELKI

    Free Mac Windows Linux Website

    ELKI: "Environment for Developing KDD-Applications Supported by Index-Structures" is a development framework for data mining algorithms written in Java. It includes a large variety of popular data mining algorithms, distance functions and index structures.

    Its focus is particularly on clustering and outlier detection methods, in contrast to many other data mining toolkits that focus on classification. Additionally, it includes support for index structures to improve algorithm performance such as R*-Tree and M-Tree.

    The modular architecture is meant to allow adding custom components such as distance functions or algorithms, while being able to reuse the other parts for evaluation.
