Predictive technology offered by vendors like RichRelevance, Baynote, ExactTarget and Sailthru will no longer be a secret. PredictionIO, the open source machine learning server, has released a suite of five e-commerce predictive engines, with a complete customizable source code and access to the algorithms. Instead of offering personalized prediction features by a blackbox, PredictionIO disrupts the industry by open sourcing all different prediction engines’ code for e-commerce businesses. Developers and data scientists in e-commerce and mobile commerce companies can use them at no cost. The Silicon Valley-based company has mainly US, Europe and India-based users, and has active users and an open source contributor community in China.
