Hyperparameters settings for Implicit matrix factorization algorithm.

[RuihongQiu]

New beginner for recommender system. I don't know how to tune the hyperparameters and don't know what is a literally good result. I would like to know what is a proper setting of hyperparameters for the simple Implicit matrix factorization method.

My example codes is like this.

The result is like this.

The MRR and the RMSE scores seem to be not that good for training set or testing, though there is clear overfitting here.

Thanks!

I would encourage you not to use the explicit models. Try the implicit model and see if you can improve MRR?

I will have a try. Thanks!
