Hermes is Lab41's foray into recommender systems. It explores how to choose a recommender system for a new application by analyzing the performance of multiple recommender system algorithms on a variety of datasets.

It also explores how recommender systems may assist a software developer of data scientist find new data, tools, and computer programs.

The Wiki associated with this project has details on many references that we utilized when implementing this framework. It also details the datasets used in this base framework, as well as some resources to help you get started in recommender systems and Spark.

For tips on how to get started, see the wiki page: Running Hermes.
