ExPO-HM: Learning to Explain-then-Detect for Hateful Meme Detection

ICLR 2026poster

Hateful memes have emerged as a particularly challenging form of online abuse, motivating the development of automated detection systems. Most prior approaches rely on direct detection, producing only binary predictions. Such models fail to provide the context and explanations that real-world modera…

FlowCut: Rethinking Redundancy via Information Flow for Efficient Vision-Language Models

NeurIPS 2025poster

Large vision-language models (LVLMs) excel at multimodal understanding but suffer from high computational costs due to redundant vision tokens. Existing pruning methods typically rely on single-layer attention scores to rank and prune redundant visual tokens to solve this inefficiency. However, as t…

LAKE-RED: Camouflaged Images Generation by Latent Background Knowledge Retrieval-Augmented Diffusion

CVPR 2024poster

Camouflaged vision perception is an important vision task with numerous practical applications. Due to the expensive collection and labeling costs this community struggles with a major bottleneck that the species category of its datasets is limited to a small number of object species. However the ex…

Decouple Before Interact: Multi-Modal Prompt Learning for Continual Visual Question Answering

ICCV 2023poster

In the real world, a desirable Visual Question Answering model is expected to provide correct answers to new questions and images in a continual setting (recognized as CL-VQA). However, existing works formulate CLVQA from a vision-only or language-only perspective, and straightforwardly apply the un…

Prompt Switch: Efficient CLIP Adaptation for Text-Video Retrieval

ICCV 2023poster

In text-video retrieval, recent works have benefited from the powerful learning capabilities of pre-trained text-image foundation models (e.g., CLIP) by adapting them to the video domain. A critical problem for them is how to effectively capture the rich semantics inside the video using the image en…
