RapidMiner (formerly YALE) is a flexible Java environment for knowledge discovery in databases, machine learning, and data mining. Many nestable learning and preprocessing operators (including Weka) are provided. It features an XML-based graphical user interface, a plugin mechanism, and high-dimensional plotting, and provides an easy-to-use extension mechanism that makes it possible to integrate new operators and adapt the system to your personal requirements. A command line version is also included.


The project was renamed from YALE to RapidMiner. It offers a completely revised and more intuitive user interface. The huge amount of new data mining operators include outlier detection, association rule mining, and many new preprocessing and ETL methods. The API was also revised to enhance the integration of RapidMiner into other applications. The former clustering plugin is now part of the RapidMiner core. This version also provides many bugfixes and the latest Weka version.
