ActiShade: Activating Overshadowed Knowledge to Guide Multi-Hop Reasoning in Large Language Models

AAAI 2026technical

In multi-hop reasoning, multi-round retrieval-augmented generation (RAG) methods typically rely on LLM-generated content as the retrieval query. However, these approaches are inherently vulnerable to knowledge overshadowing—a phenomenon where critical information is overshadowed during generation.

Reasoning-Driven Anomaly Detection and Localization with Image-Level Supervision

CVPR 2026

Multimodal large language models (MLLMs) have recently demonstrated remarkable reasoning and perceptual abilities for anomaly detection. However, most approaches remain confined to image-level anomaly detection and textual reasoning, while pixel-level localization still relies on external vision mod

Towards Training-free Anomaly Detection with Vision and Language Foundation Models

CVPR 2025poster

Anomaly detection is valuable for real-world applications, such as industrial quality inspection. However, most approaches focus on detecting local structural anomalies while neglecting compositional anomalies incorporating logical constraints. In this paper, we introduce LogSAD, a novel multi-modal…
