SONA-0.1.0-release

Spark On Angel (SONA), arming Spark with a powerful Parameter Server, which enable Spark to train very big models

Similar to Spark MLlib, Spark on Angel is a standalone machine learning library built on Spark (yet it does not rely on Spark MLlib, Figure 1). SONA was based on RDD APIs and only included model training step in previous versions. In Angel 3.0, we introduce various new features to SONA:

• add spark feature engineering
• add long index support for all feature engineering operator
• new version of LINE and Word2Vec
• spark-fashion APIs for all machine learning algorithms
• automl supported
• extend livsvm format, add two new format libFFM and Dummy
