QLPO: Quadrant-weighted Sampling for Length-aware Policy Optimization
Siwei Chen, Siqi Chen, Xupeng Miao +1
Recent large reasoning models often develop long chain-of-thought responses during reinforcement learning (RL), resulting in high inference latency and deployment cost. Existing me…
Conditionally Whitened Generative Models for Probabilistic Time Series Forecasting
Yanfeng Yang, Siwei Chen, Pingping Hu +6
Probabilistic forecasting of multivariate time series is challenging due to non-stationarity, inter-variable dependencies, and distribution shifts. While recent diffusion and flow…
Do Graph Diffusion Models Accurately Capture and Generate Substructure Distributions?
Xiyuan Wang, Yewei Liu, Lexi Pang +2
Diffusion models have gained popularity in graph generation tasks; however, the extent of their expressivity concerning the graph distributions they can learn is not fully understo…
WHALES: A Multi-Agent Scheduling Dataset for Enhanced Cooperation in Autonomous Driving
Yinsong Wang, Siwei Chen, Ziyi Song +1
Cooperative perception research is hindered by the limited availability of datasets that capture the complexity of real-world Vehicle-to-Everything (V2X) interactions, particularly…
Differentiable Particles for General-Purpose Deformable Object Manipulation
Siwei Chen, Yiqing Xu, Cunjun Yu +2
Deformable object manipulation is a long-standing challenge in robotics. While existing approaches often focus narrowly on a specific type of object, we seek a general-purpose algo…
