How Reasoning Influences Intersectional Biases in Vision–Language Models (Student Abstract)

AAAI 2026technical

Vision-Language Models (VLMs) are increasingly deployed across downstream tasks, yet their training data often encode social biases that surface in outputs. Unlike humans, who interpret images through contextual and social cues, VLMs process them through statistical associations, often leading to re

LATA: Laplacian-Assisted Transductive Adaptation for Conformal Uncertainty in Medical VLMs

CVPR 2026

Medical vision-language models (VLMs) are strong zero-shot recognizers for medical imaging, but their reliability under domain shift hinges on calibrated uncertainty with guarantees. Split conformal prediction (SCP) offers finite-sample coverage, yet prediction sets often become large (low efficienc

NoMoColor: Unified Noise Modulation for Enhanced Diffusion-based Image Colorization (Student Abstract)

AAAI 2026technical

We present a language-based noise modulation module for diffusion models that improves image color generation under textual guidance. Unlike standard approaches that inject noise uniformly, our method leverages semantic cues from text to selectively control the noise injection process, preserving l

VALIANT: Prompt Instability for Active Learning in Black-Box Medical Imaging

AAAI 2026technical

The deployment of large, black-box foundation models for medical image classification is often hindered by the high cost of acquiring large, task-specific labeled datasets for fine-tuning. While active learning (AL) presents a promising solution, many state-of-the-art AL methods are computationally

Dual-Stage Value-Guided Inference with Margin-Based Reward Adjustment for Fast and Faithful VLM Captioning

NeurIPS 2025poster

Despite significant advances in inference-time search for vision–language models (VLMs), existing approaches remain both computationally expensive and prone to unpenalized, low-confidence generations which often lead to persistent hallucinations. We introduce \textbf{Value-guided Inference with Marg…
