Taking advantage of context features

into our models, but we haven't explored whether those features improve model accuracy. Data sparsity: using non-id features may be critical if data is sparse. However, we change it slightly to allow us to turn timestamp features on or off. query_embeddings = self.query_model({ "user_id": features["user_id"], "timestamp": features the result change if we add time features?

Using side features: feature preprocessing

Numerical features need to be normalized so that their values lie in a small interval around 0. The MovieLens dataset Let's first have a look at what features we can use from the MovieLens dataset: The first two are categorical features; timestamps are a continuous feature. Continuous features also need normalization. Processing text features We may also want to add text features to our model.
