This bundle provides easy integration with PredictionIO. PredictionIO is an open source machine learning server for software developers to create predictive features, such as personalization, recommendation and content discovery. Based on Apache Mahout scalable machine learning libraries.

The bundle registers the Endroid PredictionIO client as a service in your Symfony project. This client can then be used to register actions between users and items and to retrieve recommendations provided by any PredictionIO server. Applications range from showing recommended products in a web shop to discovering relevant experts in a social collaboration network.
