Learning Spatiotemporal Decision Priors for Efficient Path Planning under Partial Observability
Yi Liu, Hongda Zhang, Leyao Zou +7
Path planning under partial observability remains challenging because an agent must make long-horizon navigation decisions from only locally bounded observations. Nevertheless, his…
Pheromone-Focused Ant Colony Optimization algorithm for path planning
Yi Liu, Hongda Zhang, Zhongxue Gan +4
Ant Colony Optimization (ACO) is a prominent swarm intelligence algorithm extensively applied to path planning. However, traditional ACO methods often exhibit shortcomings, such as…
ViG3D-UNet: Volumetric Vascular Connectivity-Aware Segmentation via 3D Vision Graph Representation
Bowen Liu, Chunlei Meng, Wei Lin +4
Accurate vascular segmentation is essential for coronary visualization and the diagnosis of coronary heart disease. This task involves the extraction of sparse tree-like vascular b…
CTA-Net: A CNN-Transformer Aggregation Network for Improving Multi-Scale Feature Extraction
Chunlei Meng, Jiacheng Yang, Wei Lin +4
Convolutional neural networks (CNNs) and vision transformers (ViTs) have become essential in computer vision for local and global feature extraction. However, aggregating these arc…
