Controllable Exploration in Hybrid-Policy RLVR for Multi-Modal Reasoning

ICLR 2026poster

Reinforcement Learning with verifiable rewards (RLVR) has emerged as a primary learning paradigm for enhancing the reasoning capabilities of multi-modal large language models (MLLMs). However, during RL training, the enormous state space of MLLM and sparse rewards often leads to entropy collapse, po…

Segment-Aligned Policy Optimization for Multi-Modal Reasoning

ICML 2026poster

Existing reinforcement learning approaches for Large Language Models typically perform policy optimization at the granularity of individual tokens or entire response sequences. However, such formulations often misalign with the natural step-wise structure of reasoning processes, leading to suboptima…

EraseAnything: Enabling Concept Erasure in Rectified Flow Transformers

ICML 2025poster

Removing unwanted concepts from large-scale text-to-image (T2I) diffusion models while maintaining their overall generative quality remains an open challenge. This difficulty is especially pronounced in emerging paradigms, such as Stable Diffusion (SD) v3 and Flux, which incorporate flow matching an…

JTD-UAV: MLLM-Enhanced Joint Tracking and Description Framework for Anti-UAV Systems

CVPR 2025poster

Unmanned Aerial Vehicles (UAVs) are widely adopted across various fields, yet they raise significant privacy and safety concerns, demanding robust monitoring solutions. Existing anti-UAV methods primarily focus on position tracking but fail to capture UAV behavior and intent. To address this, we int…

ScalaLog: Scalable Log-Based Failure Diagnosis Using LLM

ICASSP 2025accepted

As Industrial Internet of Things (IIoT) software systems become increasingly complex, precise failure diagnosis has become both essential and challenging. Current log-based failure diagnosis methods lack scalability for different failure types. In IIoT software systems, the number of failure types i…

Panoptic Compositional Feature Field for Editable Scene Rendering With Network-Inferred Labels via Metric Learning

CVPR 2023poster

Despite neural implicit representations demonstrating impressive high-quality view synthesis capacity, decomposing such representations into objects for instance-level editing is still challenging. Recent works learn object-compositional representations supervised by ground truth instance annotation…

Semi-attention Partition for Occluded Person Re-identification

AAAI 2023technical

This paper proposes a Semi-Attention Partition (SAP) method to learn well-aligned part features for occluded person re-identification (re-ID). Currently, the mainstream methods employ either external semantic partition or attention-based partition, and the latter manner is usually better than the fo…

Matching on Sets: Conquer Occluded Person Re-identification Without Alignment

AAAI 2021technical

Occluded person re-identification (re-ID) is a challenging task as different human parts may become invisible in cluttered scenes, making it hard to match person images of different identities. Most existing methods address this challenge by aligning spatial features of body parts according to seman…

A Similarity Inference Metric for RGB-Infrared Cross-Modality Person Re-identification

IJCAI 2020poster

RGB-Infrared (IR) cross-modality person re-identification (re-ID), which aims to search an IR image in RGB gallery or vice versa, is a challenging task due to the large discrepancy between IR and RGB modalities. Existing methods address this challenge typically by aligning feature distributions or i…

Multiple Expert Brainstorming for Domain Adaptive Person Re-identification

ECCV 2020poster

Often the best performing deep neural models are ensembles of multiple base-level networks, nevertheless, ensemble learning with respect to domain adaptive person re-ID remains unexplored. In this paper, we propose a multiple expert brainstorming network (MEB-Net) for domain adaptive person re-ID, o…
