Hybrid-Policy Self-Editing for Composable Unstructured Knowledge Editing

Tianci Liu, Zihan Dong, Tianchun Li +8

Large language models (LLMs) achieve remarkable performance across natural language tasks, yet they are trained on static corpora and their knowledge quickly becomes outdated in a…

KAMR: Grounding Generation via Knowledge-Aligned Multi-hop Retrieval

Xiaochen Wang, Yuan Zhong, Haoyu Wang +2

The paper presents KAMR, a knowledge‑aligned multi‑hop retriever that first identifies anchor graph triplets strongly tied to a query and then locally expands to connected evidence…

RIMS: Preference Optimization via Smoothed Multi-pair Aggregation for Small-Scale LLM Retrieval-Augmented Generation

Pei Tian, Zihan Dong, Tianci Liu +2

Small-scale language models (SLMs) are attractive for retrieval-augmented generation (RAG) in resource-constrained settings, but their limited capacity makes them highly sensitive…

PEANuT: Parameter-Efficient Adaptation with Weight-aware Neural Tweakers

Yibo Zhong, Haoxiang Jiang, Lincan Li +5

Fine-tuning large pre-trained foundation models often yields excellent downstream performance but is prohibitively expensive when updating all parameters. Parameter-efficient fine-…
