title: Predictive Analysis using Java
body: <p>I am working on a Spring based Web application which performs Predictive Analysis based on the user historical data and come up with offers to users. I need to implement a Predictive Analysis or any regression kind of functionality which gives a confidence score/prediction to present those offers. I am a Java developer and looked at Weka, Mahout to get the desired result. But both the tools dont provide good documentation and it is highly difficult to proceed with them. I need a suggestion regarding Java based analytics API to process my data using regression or Neural Networks or Decision Trees and provides a confidence score depicting customers probablity on buying the product in future.</p>
  
  <p>Any help in this regard is highly appreciable.</p>
