Dr. Seg: Revisiting GRPO Training for Visual Large Language Models through Perception-Oriented Design

CVPR 2026

Following the success of Group Relative Policy Optimization (GRPO) in foundation LLMs, an increasing number of works have sought to adapt GRPO to Visual Large Language Models (VLLMs) for visual perception tasks (e.g., detection and segmentation). However, much of this line of research rests on a lon

Rethinking KV Cache Eviction via a Unified Information-Theoretic Objective

ICML 2026poster

Key–value (KV) caching is essential for large language model inference, yet its memory overhead poses a critical bottleneck for long-context generation. Existing eviction policies predominantly rely on empirical heuristics, lacking a rigorous theoretical foundation. This work rethinks KV cache evict…

S3Net: Spatiotemporally Separated Sparse Network for Neuromorphic Vision Processing

AAAI 2026technical

Dynamic Vision Sensor (DVS) asynchronously records sparse events triggered by changes in pixel intensity, offering high temporal resolution and low latency. Existing frame-based methods process event data densely, violating its inherent sparsity and introducing computational redundancy. While asynch

PALA: Class-imbalanced Graph Domain Adaptation via Prototype-anchored Learning and Alignment

IJCAI 2025

Graph domain adaptation is a key subfield of graph transfer learning that aims to bridge domain gaps by transferring knowledge from a label-rich source graph to an unlabeled target graph. However, most existing methods assume balanced labels in the source graph, which often fails in practice and lea

Zero-Shot Aerial Object Detection with Visual Description Regularization

AAAI 2024technical

Existing object detection models are mainly trained on large-scale labeled datasets. However, annotating data for novel aerial object classes is expensive since it is time-consuming and may require expert knowledge. Thus, it is desirable to study label-efficient object detection methods on aerial im…
