[Pytorch] Generative retrieval model using semantic IDs from "Recommender Systems with Generative Retrieval"

[Pytorch] Unofficial Implementation of "Recommender Systems with Generative Retrieval"

Updating curated list of research advancements on item identification and item tokenization in generative recommender systems. The survey is titled "A Survey of Item Identifiers in Generative Recommendation: Construction, Alignment, and Generation"

Official Implementation of GENIUS: A Generative Framework for Universal Multimodal Search, CVPR 2025

We introduce the direct document relevance optimization (DDRO) for training a pairwise ranker model. DDRO encourages the model to focus on document-level relevance during generation
