RapidMiner (YALE)

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.

          Release Notes: This release focuses on the most requested data analysis, ETL, and BI requirements. It provides more than 50 new operators and a lot of new features including upgraded data pivotings, new aggregation functions, and date and time handling. The usage of function-based attribute construction was simplified, and optimized wizards or new visualizations, including zooming and panning, were added. More powerful processes are now possible due to enhanced macros and the new result storage mechanism. This release also provides fixes for more than 30 bugs.

          •  15 Aug 2008 17:15

            Release Notes: This is a minor bugfix and feature release. In particular, two errors that caused problems in the new parameter optimization wizard for string and integer parameters were fixed. New features include a new 64-bit version for Windows x64 systems, multiple groupings for aggregations, better support for date and time columns, the grouping and ungrouping of models, and an improved attribute subset preprocessing. Additionally, the runtime of several analysis schemes was drastically reduced, in some cases up to a factor of 13.
