Multiplicative Orthogonal Sequential Editing for Language Models

AAAI 2026technical

Knowledge editing aims to efficiently modify the internal knowledge of large language models (LLMs) without compromising their other capabilities. The prevailing editing paradigm, which appends an update matrix to the original parameter matrix, has been shown by some studies to damage key numerical

Orthogonal Concept Erasure for Diffusion Models

ICML 2026oral

Concept erasure has emerged as a promising approach to mitigate undesired or unsafe content in diffusion models, yet existing methods still face significant limitations. While training-based methods are effective, their high computational cost limits scalability. Editing-based methods are more effic…

TangleScore: Tangle-Guided Purge and Imprint for Unstructured Knowledge Editing

ICLR 2026poster

Large language models (LLMs) struggle with inaccurate and outdated information, driving the emergence of knowledge editing as a lightweight alternative. Despite their effectiveness in modifying structured knowledge, existing editing methods often fail to generalize to unstructured cases, particularl…

Constraining Sequential Model Editing with Editing Anchor Compression

NAACL 2025findings

Large language models (LLMs) struggle with hallucinations due to false or outdated knowledge. Given the high resource demands of retraining these models, there is an increasing focus on developing model editing. However, the general abilities of LLMs across downstream tasks are prone to significant…

Perturbation-Restrained Sequential Model Editing

ICLR 2025poster

Model editing is an emerging field that focuses on updating the knowledge embedded within large language models (LLMs) without extensive retraining. However, current model editing methods significantly compromise the general abilities of LLMs as the number of edits increases, and this trade-off pose…

Model Editing Harms General Abilities of Large Language Models: Regularization to the Rescue

EMNLP 2024main

Model editing is a technique that edits the large language models (LLMs) with updated knowledge to alleviate hallucinations without resource-intensive retraining. While current model editing methods can effectively modify a model’s behavior within a specific area of interest, they often overlook the…
