SAGE: Spuriousness-Aware Guided Prompt Exploration for Mitigating Multimodal Bias

AAAI 2026technical

Large vision-language models such as CLIP have shown strong zero-shot classification performance by aligning images and text in a shared embedding space. However, CLIP models often develop multimodal spurious biases, the undesirable tendency to rely on spurious features. For example, CLIP may infer

Toward Faithful Retrieval-Augmented Generation with Sparse Autoencoders

ICLR 2026poster

Retrieval-Augmented Generation (RAG) improves the factuality of large language models (LLMs) by grounding outputs in retrieved evidence, but faithfulness failures, where generations contradict or extend beyond the provided sources, remain a critical challenge. Existing hallucination detection method…

Online Reasoning Video Segmentation with Just-in-Time Digital Twins

ICCV 2025poster

Reasoning segmentation (RS) aims to identify and segment objects of interest based on implicit text queries. As such, RS is a catalyst for embodied AI agents, enabling them to interpret high-level commands without requiring explicit step-by-step guidance. However, current RS approaches rely heavily…
