I'm glad to have won the hackathon championship this time! The accuracy of our music prediction algorithm reaches RMSE = 13.24598.

The implicit feedbacks of SVD ++ did not play a major role this time. On the contrary, 86 feature columns in words are of great help and used in logistic regression. In addition, the combination of various profiles, items, and artist of users also brings good results.

The competition is described as follows:
