Hopformer: Homogeneity-Pursuit Transformer for Time Series Forecasting

Wan Zhang, Qinjie Lin, Chan Lee, Weijian Li, Han Liu, Kai Zhang

Forecasting multiple time-series with high-dimensional covariates presents a core challenge: unifying common temporal patterns while retaining meaningful series-specific information. We introduce Hopformer (Homogeneity-Pursuit Transformer), a two-stage framework that addresses th…

Progress Reward Modeling for Robotic Learning: A Comprehensive Survey

Jianshu Zhang, Keliang Wu, Haoran Lu, Anbang Liu, Ce Zhang, Weijie Yin, et al.

Robotic learning takes place in dynamic environments with large behavior spaces. A terminal success signal only tells the robot whether the task is completed. It does not explain whether the current behavior is making progress, remaining unchanged, or undoing earlier progress. Fo…

SPINE: Bridging the Cyber-Physical Gap with Agentic AI

Minkyu Ham, Dongho Kim, Chan Lee, Jiayi Wang, Min Jun Kim, Yixi Zhang, et al.

Foundation models have given robots a sophisticated brain for complex decision-making, yet deploying that intelligence into a physical platform still demands tedious, expert-driven calibration. This deployment gap, the robot's spinal cord, remains a primary bottleneck to scalable…
