Annotation-Free Visual Reasoning for High-Resolution Large Multimodal Models via Reinforcement Learning

This paper proposes HART, an annotation-free framework that leverages a novel Advantage Preference Group Relative Policy Optimization (AP-GRPO) algorithm to enable Large Multimodal Models to autonomously identify and verify key high-resolution image regions, thereby improving reasoning performance without requiring costly human grounding labels.

Self-Attention And Beyond the Infinite: Towards Linear Transformers with Infinite Self-Attention

This paper introduces Infinite Self-Attention (InfSA) and its linear-time variant, Linear-InfSA, a spectral reformulation of self-attention as a diffusion process on token graphs that achieves state-of-the-art ImageNet accuracy and enables efficient, memory-free inference at ultra-high resolutions (up to 9216×9216) by replacing the quadratic softmax cost with a Neumann series approximation.

DeAR: Fine-Grained VLM Adaptation by Decomposing Attention Head Roles

The paper proposes DeAR, a fine-grained adaptation framework for Vision-Language Models that decomposes attention heads into functional roles (Attribute, Generalization, and Mixed) using a Concept Entropy metric to selectively isolate task-specific learning from generalization capabilities, thereby achieving superior performance across diverse tasks while preserving zero-shot robustness.

DINOv3 Visual Representations for Blueberry Perception Toward Robotic Harvesting

This paper evaluates DINOv3 as a frozen backbone for blueberry robotic harvesting tasks, finding that while it excels in segmentation through stable patch-level representations, its detection performance is limited by scale variation and spatial aggregation challenges, suggesting it functions best as a semantic backbone requiring downstream spatial modeling tailored to fruit structures.

LDP-Slicing: Local Differential Privacy for Images via Randomized Bit-Plane Slicing

This paper introduces LDP-Slicing, a lightweight, training-free framework that overcomes the utility limitations of applying Local Differential Privacy to high-dimensional images by decomposing pixel values into binary bit-planes and integrating perceptual obfuscation and optimized budget allocation to achieve rigorous privacy with high downstream task performance.

Roots Beneath the Cut: Uncovering the Risk of Concept Revival in Pruning-Based Unlearning for Diffusion Models

This paper reveals that pruning-based unlearning in diffusion models is inherently insecure because the locations of pruned weights act as side-channel signals that enable a novel, data-free, and training-free attack to fully revive erased concepts, prompting a call for safer pruning mechanisms that conceal these locations.
