AI Frameworks for Scala

Deep Learning/Neural Networks

Machine Learning

  • SMILE, Haifeng Li’s Statistical Machine Intelligence and Learning Engine, includes a Scala API and relies on ND4J/ND4S for numerical computation.

  • Cortex - Twitter uses Scala for much of its big data stack.

  • MLlib is part of Apache Spark. While it includes several popular machine learning algorithms, it is not archtected to perform computation efficiently. For better architectures using Spark for machine learning, here is Deeplearning4j’s integration with Apache Spark for distributed neural net training.

  • MxNet has a Scala API.


  • For natural language processing in Scala, see Scala NLP.

Numerical Computing

  • Breeze is a numerical computing library written in Scala. Unlike ND4J/ND4S, it does not support n-dimensional arrays, or tensors.
