Focusing Where Vision Matters: Selective Training for Large Vision Language Models via Visual Information Gain

ICML 2026poster

Large Vision Language Models (LVLMs) have achieved remarkable progress, yet they often suffer from language bias, producing answers without relying on visual evidence. While prior work attempts to mitigate this issue through decoding strategies, architectural modifications, or curated instruction da…

Localized Concept Erasure in Text-to-Image Diffusion Models via High-Level Representation Misdirection

ICLR 2026poster

Recent advances in text-to-image (T2I) diffusion models have seen rapid and widespread adoption. However, their powerful generative capabilities raise concerns about potential misuse for synthesizing harmful, private, or copyrighted content. To mitigate such risks, concept erasure techniques have em…

APT: Adaptive Personalized Training for Diffusion Models with Limited Data

CVPR 2025poster

Personalizing diffusion models using limited data presents significant challenges, including overfitting, loss of prior knowledge, and degradation of text alignment. Overfitting leads to shifts in the noise prediction distribution, disrupting the denoising trajectory and causing the model to lose se…

Enhanced OoD Detection through Cross-Modal Alignment of Multi-Modal Representations

CVPR 2025poster

Prior research on out-of-distribution detection (OoDD) has primarily focused on single-modality models. Recently, with the advent of large-scale pretrained vision-language models such as CLIP, OoDD methods utilizing such multi-modal representations through zero-shot and prompt learning strategies ha…

Confidence-Aware Learning for Deep Neural Networks

ICML 2020poster

Despite the power of deep neural networks for a wide range of tasks, an overconfident prediction issue has limited their practical use in many safety-critical applications. Many recent works have been proposed to mitigate this issue, but most of them require either additional computational costs in…
