Datumbox

The Datumbox Machine Learning Framework is an open-source framework written in Java which allows the rapid development Machine Learning and Statistical applications. The main focus of the framework is to include a large number of machine learning algorithms & statistical methods and to be able to handle large sized datasets.

Copyright & License

Copyright (C) 2013-2016 Vasilis Vryniotis.

The code is licensed under the Apache License, Version 2.0.

Version

The latest version is 0.7.0 (Build 20160319).

The master branch is the latest stable version of the framework. The devel branch is the development branch. All the previous stable versions are marked with tags.

The releases of the framework follow the Semantic Versioning approach. For detailed information about the various releases check out the Changelog.

Installation

Datumbox Framework is available on Maven Central Repository.

Maven:

    <dependency>
        <groupId>com.datumbox</groupId>
        <artifactId>datumbox-framework-lib</artifactId>
        <version>0.7.0</version>
    </dependency>

Note: A couple of classes which use Linear Programming require installing an external C library called lpsolve. Most users won't use these classes and thus installing the binary library can be considered optional; please check the Detailed Installation Guide for more info.

Documentation and Code Examples

All the public methods and classes of the Framework are documented with Javadoc comments. Moreover for every model there is a JUnit Test which clearly shows how to train and use the models. Finally for more examples on how to use the framework checkout the Code Examples or the official Blog.

Technical Details

The framework requires Java 8, it uses a Maven Project Structure and it is separated in different modules.

Which methods/algorithms are supported?

The Framework currently supports performing multiple Parametric & non-parametric Statistical tests, calculating descriptive statistics on censored & uncensored data, performing ANOVA, Cluster Analysis, Dimension Reduction, Regression Analysis, Timeseries Analysis, Sampling and calculation of probabilities from the most common discrete and continues Distributions. In addition it provides several implemented algorithms including Max Entropy, Naive Bayes, SVM, Bootstrap Aggregating, Adaboost, Kmeans, Hierarchical Clustering, Dirichlet Process Mixture Models, Softmax Regression, Ordinal Regression, Linear Regression, Stepwise Regression, PCA and several other techniques that can be used for feature selection, ensemble learning, linear programming solving and recommender systems.

Bug Reports

Despite the fact that parts of the Framework have been used in commercial applications, not all classes are equally used/tested. Currently the framework is in Alpha version, so you should expect some changes on the public APIs on future versions. If you spot a bug please submit it as an Issue on the official Github repository.

Contributing

The Framework can be improved in many ways and as a result any contribution is welcome. By far the most important feature missing from the Framework is the ability to use it from command line or from other languages such as Python. Other important enhancements include improving the documentation, the test coverage and the examples, improving the architecture of the framework and supporting more Machine Learning and Statistical Models. If you make any useful changes on the code, please consider contributing them by sending a pull request.
