Deeplearning4J Examples for Scala

This project is a simple Scala porting of deeplearning4j-example.

The main purpose of this project is:

  • Show example of how to use deeplearning4j Java API from scala

  • Provide a sbt project template depends on DL4J

Every examples in this demonstration directly calls Java APIs of DL4J. If you strongly want to write codes in the scala manner, you should consider to use deeplearning4s.

Note that currently

are not merged yet.
