Expanding before Inferring: Enhancing Factuality in Large Language Models through Premature Layers Interpolation

EMNLP 2025

Large Language Models (LLMs) demonstrate remarkable capabilities in text understanding and generation. However, their tendency to produce factually inconsistent outputs—commonly referred to as “hallucinations”—remains a critical challenge. Existing approaches, such as retrieval-based and inference-t

Forgetting before Learning: Utilizing Parametric Arithmetic for Knowledge Updating in Large Language Models

ACL 2024long

Recent advancements in Large Language Models (LLMs) have showcased their remarkable capabilities in text understanding and generation. However, even stronger LLMs are susceptible to acquiring erroneous or obsolete information from the training corpus. Direct secondary fine-tuning with data containin…
