Building a recommendation system that is high-quality, high-performance, and hallucination-free can be a challenge. In this video, Yufeng Guo introduces Keras Recommenders (KerasRS), a library designed to help developers build reliable ranking and retrieval models with ease.
We’ll walk through a complete code example using the MovieLens dataset to build a Sequential Retrieval model. Using a Gated Recurrent Unit (GRU) to analyze a user's watch history, we will predict exactly which movie they are likely to watch next.
Because KerasRS is built on Keras 3, this workflow is compatible with your choice of backend: TensorFlow, JAX, or PyTorch.
In this video, you will learn:
- What Keras Recommenders is and why it’s useful
- How to prepare sequential data (using the "snake" method) for training
- How to build a two-tower architecture with a query tower (GRU) and candidate tower
- How to use the BruteForceRetrieval layer for accurate predictions
