FOSTER: First-order Dataset Distillation for Text-based Sequential Recommendation

Hung Vinh Tran, Tong Chen, Xinyi Gao +3

Text-based sequential recommender systems, while greatly improving recommendation accuracy by incorporating item contexts, are undeniably more expensive to train. By condensing a l…

GRAFT: Graph-Tokenized LLMs for Tool Planning

Xinyi Gao, Xinyu Ren, Junliang Yu +3

Large language models (LLMs) are increasingly used to complete complex tasks by selecting and coordinating external tools across multiple steps. This requires aligning tool choices…
