Constructing Good Abelian Codes via Shift Bounds and Genetic Algorithms
Cong Yu, Hao Chen, Zhonghua Sun +1
This paper investigates the construction of linear codes via abelian codes over finite fields. By exploiting the algebraic structure of multivariate polynomial quotient rings, we d…
Backward Layout Search for Sequence-Constrained Robotic Assembly
Xi Zhang, Jiancong Dai, Hao Chen +3
Robotic assembly layout planning must determine the assembly site and the initial pose of each part while ensuring collision-free execution of a prescribed assembly sequence. This…
HarvestPoint-ACT: Explicit Target Selection and Harvest-Point Conditioning for Robotic Fruit Harvesting under Occlusion
Hanying Hu, Weipeng Li, Yikun Huang +4
End-to-end imitation learning avoids hand-made robot motion for approaching and grasping, but the policy must still decide which fruit to pick and where to close the gripper. Occlu…
EgoCITE: Context-Augmented Indexing and Time-Aware Retrieval for Long-Horizon Egocentric Memory
Le Zhang, Hao Chen, Vlad Roznyatovskiy +2
Long-horizon egocentric memory transforms continuous first-person video and audio into a searchable record of past experiences. We demonstrate two bottlenecks in existing systems:…
