Recommendation engines are powerful tools that make browsing content easier. Moreover, a great recommendation system helps users find things they wouldn’t have thought to look for on their own. For these reasons, recommendation tools can dramatically boost e-commerce turnover. Here we show how we — at Decathlon France — implemented a RNN (recurrent neural network) recommendation system that outperforms our previous model (ALS, alternating least square) by more than 20% on Precision metric (off-line).
