Deep AutoEncoders for Collaborative Filtering
- jeremynixon 9y agoAccording to the nextflix prize leaderborad at http://www.netflixprize.com/leaderboard.html http://www.netflixprize.com/leaderboard.html, this result wouldn't even be in the top 1000. More than that, due to the absence of compositional structure in the data I wouldn't expect this approach to work well. Would love to hear more insights, I'm digging into the paper now. All that said, open code for running this on arbitrary data is great to have! A thanks to Oleksii Kuchaiev.
- lsorber 9y agoYou're comparing ensemble performance with single model performance. The test set RMSE the authors are able to achieve with their model is pretty impressive to me considering it is a single model that doesn't even exploit the time dimension.
