Description

Hi all,
as I delved further into the topic of recommender systems, the question came up of what the difference is between the two-tower model used here "https://www.tensorflow.org/recommenders/examples/basic_retrieval" and neural collaborative filtering (https://arxiv.org/abs/1708.05031).

Many thanks in advance.

Research direction

Start with the TensorFlow Recommenders basic retrieval example and the linked neural collaborative filtering paper. Compare their architectures and training objectives, then provide a clear explanation of the difference and how each approach is used; completion means the question is answered for readers without requiring further project context.
