Toward Holistic Evaluation of Recommender Systems Powered by Generative Models

Yashar Deldjoo, Nikhil Mehta, Maheswaran Sathiamoorthy +3

Recommender systems powered by generative models (Gen-RecSys) extend beyond classical item ranking by producing open-ended content, which simultaneously unlocks richer user experie…

A Review of Modern Recommender Systems Using Generative Models (Gen-RecSys)

Yashar Deldjoo, Zhankui He, Julian McAuley +7

Traditional recommender systems (RS) typically use user-item rating histories as their main data source. However, deep generative models now have the capability to model and sample…

Aligning Large Language Models with Recommendation Knowledge

Yuwei Cao, Nikhil Mehta, Xinyang Yi +5

Large language models (LLMs) have recently been used as backbones for recommender systems. However, their performance often lags behind conventional methods in standard tasks like…

Better Generalization with Semantic IDs: A Case Study in Ranking for Recommendations

Anima Singh, Trung Vu, Nikhil Mehta +9

Randomly-hashed item ids are used ubiquitously in recommendation models. However, the learned representations from random hashing prevents generalization across similar items, caus…

Do LLMs Understand User Preferences? Evaluating LLMs On User Rating Prediction

Wang-Cheng Kang, Jianmo Ni, Nikhil Mehta +4

Large Language Models (LLMs) have demonstrated exceptional capabilities in generalizing to new tasks in a zero-shot or few-shot manner. However, the extent to which LLMs can compre…

Recommender Systems with Generative Retrieval

Shashank Rajput, Nikhil Mehta, Anima Singh +10

Modern recommender systems perform large-scale retrieval by first embedding queries and item candidates in the same unified space, followed by approximate nearest neighbor search t…
