The first step to create a new engine is to browse PredictionIO template gallery where you could find Engine Templates for all kinds of machine learning tasks. Choose an engine template that matches your use case the best. You can further customize the engine later if you like.
To download a template, run:
$ pio template get <template-repo-path> <new-engine-directory>
For example, to download the template “PredictionIO/template-scala-parallel-recommendation” to your directory “MyRecommendation”, run:
$ pio template get PredictionIO/template-scala-parallel-recommendation MyRecommendation
NOTE: pio is a command available in the bin/ of the installed PredictionIO directory. You may add the installed Prediction's bin/ directory path to you environment PATH.
Please browse the PredictionIO template gallery to choose an engine template.
