Variational Autoencoder

Variational Autoencoders are a type of generative model that are excellent at learning latent representations of data, allowing for efficient data encoding and generation. We've demonstrated a 50% improvement over Matrix Factorization/Linear models in recall accuracy. This model is very lightweight and fast to train, requiring only user IDs and item ID interactions as input. Its simplicity and efficiency make it an attractive choice for recommendation tasks where computational resources and training time are limited.
