A Direct Semi-Exhaustive Search Method for Robust, Partial-to-Full Point Cloud Registration

no code implementations31 Jan 2025 Richard Cheng, Chavdar Papozov, Dan Helmick, Mark Tjersland

Point cloud registration refers to the problem of finding the rigid transformation that aligns two given point clouds, and is crucial for many applications in robotics and computer vision.

Human Preference-Based Learning for High-dimensional Optimization of Exoskeleton Walking Gaits

1 code implementation13 Mar 2020 Maegan Tucker, Myra Cheng, Ellen Novoseller, Richard Cheng, Yisong Yue, Joel W. Burdick, Aaron D. Ames

Optimizing lower-body exoskeleton walking gaits for user comfort requires understanding users' preferences over a high-dimensional gait parameter space.

Control Regularization for Reduced Variance Reinforcement Learning

1 code implementation14 May 2019 Richard Cheng, Abhinav Verma, Gabor Orosz, Swarat Chaudhuri, Yisong Yue, Joel W. Burdick

We show that functional regularization yields a bias-variance trade-off, and propose an adaptive tuning strategy to optimize this trade-off.

End-to-End Safe Reinforcement Learning through Barrier Functions for Safety-Critical Continuous Control Tasks

1 code implementation21 Mar 2019 Richard Cheng, Gabor Orosz, Richard M. Murray, Joel W. Burdick

Reinforcement Learning (RL) algorithms have found limited success beyond simulated applications, and one main reason is the absence of safety guarantees during the learning process.
