A Multi-Agent Perception-Action Alliance for Efficient Long Video Reasoning

CVPR 2026

This paper presents a multi-agent perception-action exploration alliance, dubbed A4VL, for efficient long-video reasoning. A4VL operates in a multi-round perception-action exploration loop with a selection of VLM agents. In each round, the team of agents performs video question-answer (VideoQA) via

Attention-aware Inference Optimizations for Large Vision-Language Models with Memory-efficient Decoding

CVPR 2026

Large Vision-Language Models (VLMs) have achieved remarkable success in multi-modal reasoning, but their inference time efficiency remains a significant challenge due to the memory overhead during decoding, especially when the query and answer of VLMs consist of long sequences of visual and text tok

Adversarial Attention Perturbations for Large Object Detection Transformers

ICCV 2025poster

Adversarial perturbations are useful tools for exposing vulnerabilities in neural networks. Existing adversarial perturbation methods for object detection are either limited to attacking CNN-based detectors or weak against transformer-based detectors. This paper presents an Attention-Focused Offensi…
