NeuralDB: Scaling Knowledge Editing in LLMs to 100,000 Facts with Neural KV Database

Weizhi Fei, Hao Shi, Jing Xu +7

Efficiently editing knowledge stored in large language models (LLMs) enables model updates without large-scale training. One possible solution is Locate-and-Edit (L\&E), allowing s…

Efficient and Scalable Neural Symbolic Search for Knowledge Graph Complex Query Answering

Weizhi Fei, Zihao Wang, hang Yin +3

Complex Query Answering (CQA) is a crucial reasoning task over Knowledge Graphs (KGs), which aims to answer first-order logical queries from incomplete KGs. While existing neural-s…
