DuoLM — Books

Paper · GitHub · Usage guide

DuoLM brings language understanding to personalized recommendation. It combines an item encoder with a personalized ranker, using item content, user history, and feedback to model individual preferences. Item representations are computed offline and reused across recommendation requests, making inference more efficient.

This repository provides the Books model from DuoLM: Fast and Effective Personalized Recommendation with Language Models.
