Hallucination Reduction with CASAL: Contrastive Activation Steering for Amortized Learning

ICLR 2026poster

Large Language Models (LLMs) exhibit impressive capabilities but often hallucinate, confidently providing incorrect answers instead of admitting ignorance. Prior work has shown that models encode linear representations of their own knowledge and that activation steering can reduce hallucinations. Th…

FuncGenFoil: Airfoil Generation and Editing Model in Function Space

NeurIPS 2025poster

Aircraft manufacturing is the jewel in the crown of industry, in which generating high-fidelity airfoil geometries with controllable and editable representations remains a fundamental challenge. Existing deep learning methods, which typically rely on predefined parametric representations (e.g., Bézi…

Towards Understanding the Fragility of Multilingual LLMs against Fine-Tuning Attacks

NAACL 2025findings

Recent advancements in Large Language Models (LLMs) have sparked widespread concerns about their safety. Recent work demonstrates that safety alignment of LLMs can be easily removed by fine-tuning with a few adversarially chosen instruction-following examples, i.e., fine-tuning attacks. We take a fu…
