Apache PredictionIO is an open-source machine learning server built on Spark, HBase, Elasticsearch, and Hadoop that lets developers build, train, and deploy predictive engines (recommendation, classification, similar-product) as REST web services. The project has been retired to the Apache Attic and is no longer maintained.
Use cases
- deploy a recommendation engine as a REST API
- build a 'customers who viewed this also viewed' feature
- collect user events and train predictive models on Spark
- serve real-time product recommendations to anonymous visitors
- run text classification with Naive Bayes as a web service
- predict which service plan a user will subscribe to
When to choose
- you are maintaining a legacy deployment already built on PredictionIO
- you need a self-hosted ML server stack on older Spark/HBase/Elasticsearch versions
- you want to study a Lambda Architecture ML server implementation
When to avoid
- you are starting a new project - the project is retired and unmaintained
- you need current Spark, Elasticsearch, or Java versions
- you want modern ML tooling or active community support
