ANKHOR is a revolutionary platform for in-memory processing of data from diverse sources and in variable data formats.

CloudStat is the cloud environment for building statistical applications collaboratively.

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.

Calculation Laboratory is an online environment for numerical computations. By using this site you get fast access to the easy-to-use tool for computing from anywhere. Calculation Lab is perfect for engineering students.

Main features:- Performing a wide range of operations on data, such as sampling, joining datasets, dividing into testing/training/validating sets, assigning roles to attributes- Graphical and interactive data exploration- Outlier filtering, supplying missing values, PCA, various data transformations, etc.- Building association models, clustering analyses, variable importance analyses, etc.- Constructing various analytical models with the use of diverse Data Mining and statistical algorithms (such as classification trees, neuron networks, linear and logistic regression, K-means)- Creation of scoring code so that the models can be integrated with other IT applications (scoring code may include the models as well as data transformations)- Model quality evaluation and comparison of Data Mining models (LIFT, ROK, K-S, Confusion Matrix)- Generation of model quality reports (MS Office) »

Powerful forecasting software for small businesses, traders and scientists. GMDH Shell is the easiest way to accurately forecast time series, create classifiers and regression models. Based on artificial neural networks, it allows you easily create predictive models, as well as preprocess data with dead simple point-and-click interface. Unlike other tools based on neural networks - GMDH Shell is very fast because of state-of-the-art parallel processing and great optimization of core algorithms.

QIWare is an agile analytics solution that delivers a complete suite of capabilities to support end-to-end data mining cycle. Simplify data preparation and modeling while increasing business productivity, minimizing human error, and significantly improving usability.

KEEL is an open source (GPLv3) Java software tool to assess evolutionary algorithms for Data Mining problems including regression, classification, clustering, pattern mining and so on. It contains a big collection of classical knowledge extraction algorithms, preprocessing techniques (training set selection, feature selection, discretization, imputation methods for missing values, etc.), Computational Intelligence based learning algorithms, including evolutionary rule learning algorithms based on different approaches (Pittsburgh, Michigan and IRL, ...), and hybrid models such as genetic fuzzy systems, evolutionary neural networks, etc. It allows us to perform a complete analysis of any learning model in comparison to existing ones, including a statistical test module for comparison. Moreover, KEEL has been designed with a double goal: research and educational. »
