NCF-for-Implicit-Feedback

Neural collaborative filtering (NCF) method is used for Microsoft MIND news recommendation dataset.
Our approach:

construct a rating dataset from the original raw MIND dataset. Each row of the rating dataset: [User ID, Item ID, Rating Score] .
negative sampling.
we treat the positive feedback as 5, and the negative feedback as 3.
NCF implement by keras.
