EconGym: A Scalable AI Testbed with Diverse Economic Tasks

NeurIPS 2025poster

Artificial intelligence (AI) has become a powerful tool for economic research, enabling large-scale simulation and policy optimization. However, applying AI effectively requires simulation platforms for scalable training and evaluation—yet existing environments remain limited to simplified, narrowly…

IPNet: Interpretable Prototype Network for Multi-Source Domain Adaptation

ICASSP 2025accepted

Multi-source domain adaptation (MSDA) borrows intrinsic knowledge from well-annotated source domains to identify target visual signals. The main challenges are effectively mitigating cross-domain shift and extracting discriminative target features via the suitable source semantics. To overcome them,…

Internal Chain-of-Thought: Empirical Evidence for Layer‐wise Subtask Scheduling in LLMs

EMNLP 2025

We show that large language models (LLMs) exhibit an internal chain-of-thought : they sequentially decompose and execute composite tasks layer-by-layer. Two claims ground our study: (i) distinct subtasks are learned at different network depths, and (ii) these subtasks are executed sequentially acros

PSHuman: Photorealistic Single-image 3D Human Reconstruction using Cross-Scale Multiview Diffusion and Explicit Remeshing

CVPR 2025poster

Photorealistic 3D human modeling is essential for various applications and has seen tremendous progress. However, existing methods for monocular full-body reconstruction, typically relying on front and/or predicted back view, still struggle with satisfactory performance due to the ill-posed nature o…

RoBiFusion: A Robust and Bidirectional Interaction Camera-LiDAR 3D Object Detection Framework

ICRA 2025

Camera-LiDAR 3D object detection is currently becoming a crucial component in the field of autonomous driving perception. However, previous models only performed feature fusion in the deep-level BEV hierarchy when dealing with camera-LiDAR feature fusion. This approach lacks interaction with the sha

Supportive Negatives Spectral Augmentation for Source-Free Cross-Domain Segmentation

AAAI 2025technical

Source-free domain adaptation (SFDA) aims to transfer knowledge from the well-trained source model and optimize it to adapt target data distribution. SFDA methods are suitable for medical image segmentation task due to its data-privacy protection and achieve promising performances. However, cross-do…

UniMLVG: Unified Framework for Multi-view Long Video Generation with Comprehensive Control Capabilities for Autonomous Driving

ICCV 2025poster

The creation of diverse and realistic driving scenarios has become essential to enhance perception and planning capabilities of the autonomous driving system. However, generating long-duration, surround-view consistent driving videos remains a significant challenge. To address this, we present UniML…

Autonomous Generative Feature Replay for Non-Exemplar Class-Incremental Learning

ICASSP 2024accepted

Deep neural networks have been successfully applied in many computer vision tasks. However, these models suffer catastrophic forgetting when learning new knowledge incrementally. To overcome the stability-plasticity dilemma, class incremental learning (CIL) has been widely discussed recently. The st…

Discriminative Pattern Calibration Mechanism for Source-Free Domain Adaptation

CVPR 2024poster

Source-free domain adaptation (SFDA) assumes that model adaptation only accesses the well-learned source model and unlabeled target instances for knowledge transfer. However cross-domain distribution shift easily triggers invalid discriminative semantics from source model on recognizing the target s…

Hand-3d-Studio: A New Multi-View System for 3d Hand Reconstruction

ICASSP 2020accepted

This paper proposes a new system named as Hand-3D-Studio to capture the 3D hand pose and shape information. Our system includes 15 synchronized DSLR cameras, which can acquire high quality multi-view 4K resolution color images in a circular manner. We then introduce a 2D hand keypoints guided iterat…
