Myriad of virtues of Weka data mining toolkit

Weka is the swiss knife for data miners, with support for classification, clustering, regression, features selection and filtering. Data Mining book by Ian H. Witten and Eibe Frank discusses the 2005 version of Weka. I suggest using Weka for a rapid evaluation of your data mining protototypes and then a c++ robust implementation of the specific algorithm chosen.
Here you have the Weka documentation available on line with the Weka 3.6.0 manual.
