AlphaTransit: Learning to Design City-scale Transit Routes
Bibek Poudel, Sai Swaminathan, Weizi Li
Designing a transit network requires many sequential route extension decisions, but their quality is often visible only after the full network is assembled. This delayed-feedback c…
DeCoR: Design and Control Co-Optimization for Urban Streets Using Reinforcement Learning
Bibek Poudel, Lei Zhu, Kevin Heaslip +2
Modern vision systems can detect, track, and forecast urban actors at scale, yet translating perception outputs to urban design remains limited. We introduce DeCoR, a two-stage rei…
MVB-Grasp: Minimum-Volume-Box Filtering of Diffusion-based Grasps for Frontal Manipulation
Bibek Poudel, Abdul Basit, Muhammad Shafique
State-of-the-art 6-DoF grasp generators excel on tabletop benchmarks with overhead cameras but struggle in frontal grasping scenarios on low-cost manipulators with constrained work…
Learning-Guided Sparsification of Dynamic Graphs in Robotic Exploration
Adithya V. Sastry, Bibek Poudel, Weizi Li
Many robotic exploration algorithms rely on graph structures for frontier-based exploration and dynamic path planning. However, these graphs grow rapidly, accumulating redundant in…
Learning to Design City-scale Transit Routes
Bibek Poudel, Weizi Li
Designing efficient transit route networks is an NP-hard problem with exponentially large solution spaces that traditionally relies on manual planning processes. We present an end-…
Joint Pedestrian and Vehicle Traffic Optimization in Urban Environments using Reinforcement Learning
Bibek Poudel, Xuan Wang, Weizi Li +2
Reinforcement learning (RL) holds significant promise for adaptive traffic signal control. While existing RL-based methods demonstrate effectiveness in reducing vehicular congestio…
