DSCA: Dynamic Subspace Concept Alignment for Lifelong VLM Editing

Dimensions overall score 8.0

• DSCA offers a novel approach to lifelong VLM editing by structurally separating concepts into orthogonal semantic subspaces, enabling precise, non-interfering edits with state-of-the-art stability. Lifelong editing is a challenging task, prone to disrupting previously learned concepts, especially for Vision Language Models (VLMs), because sequential edits can lead to degraded reasoning and cross modal misalignment.problem 35%

• ScienceToStartup currently rates this 8.0/10 on the public viability pass. With the base model frozen, our method achieves 98 percent single edit success, remains over 95 percent after 1000 sequential edits, lowers hallucination by 3 to 5 percent, and achieves the best backward transfer (BWT) scores on continual instruction tuning benchmarks. A public repository is linked, so build verification can inspect implementation evidence instead of treating the paper as PDF-only.result 35%
