What is PredictionIO?

PredictionIO is an open source Machine Learning Server built on top of state-of-the-art open source stack for developers and data scientists create predictive engines for any machine learning task. It lets you:

  • quickly build and deploy an engine as a web service on production with customizable templates;
  • respond to dynamic queries in real-time once deployed as a web service;
  • evaluate and tune multiple engine variants systematically;
  • unify data from multiple platforms in batch or in real-time for comprehensive predictive analytics;
  • speed up machine learning modeling with systematic processes and pre-built evaluation measures;
  • support machine learning and data processing libraries such as Spark MLLib and OpenNLP;
  • implement your own machine learning models and seamlessly incorporate them into your engine;
  • simplify data infrastructure management.

PredictionIO can be installed as a full machine learning stack, bundled with Apache Spark, MLlib, HBase, Spray and Elasticsearch, which simplifies and accelerates scalable machine learning infrastructure management.
