Show HN: Gorse – An recommender system back end based on collaborative filtering

Introduction

gorse is an offline recommender system backend based on collaborative filtering written in Go.

This project is aim to provide a high performance, easy-to-use, programming language irrelevant recommender micro-service based on collaborative filtering. We could build a simple recommender system on it, or set up a more sophisticated recommender system using candidates generated by it. It features:

• Implements 7 rating based recommenders and 4 ranking based recommenders.
• Supports data loading, data splitting, model training, model evaluation and model selection.
• Provides the data import/export tool, model evaluation tool and RESTful recomender server.
