Human Motor Learning Dynamics in High-dimensional Tasks

no code implementations20 Apr 2024 Ankur Kamboj, Rajiv Ranganathan, Xiaobo Tan, Vaibhav Srivastava

Conventional approaches to enhancing movement coordination, such as providing instructions and visual feedback, are often inadequate in complex motor tasks with multiple degrees of freedom (DoFs).

Back-stepping Experience Replay with Application to Model-free Reinforcement Learning for a Soft Snake Robot

no code implementations21 Jan 2024 Xinda Qi, Dong Chen, Zhaojian Li, Xiaobo Tan

In this paper, we propose a novel technique, Back-stepping Experience Replay (BER), that is compatible with arbitrary off-policy reinforcement learning (RL) algorithms.

Derivative-Based Koopman Operators for Real-Time Control of Robotic Systems

no code implementations12 Oct 2020 Giorgos Mamakoukas, Maria L. Castano, Xiaobo Tan, Todd D. Murphey

This paper presents a generalizable methodology for data-driven identification of nonlinear dynamics that bounds the model error in terms of the prediction horizon and the magnitude of the derivatives of the system states.

Expedited Multi-Target Search with Guaranteed Performance via Multi-fidelity Gaussian Processes

no code implementations18 May 2020 Lai Wei, Xiaobo Tan, Vaibhav Srivastava

Based on the sensing model, we design a novel algorithm called Expedited Multi-Target Search (EMTS) that (i) addresses the coverage-accuracy trade-off: sampling at locations farther from the floor provides wider field of view but less accurate measurements, (ii) computes an occupancy map of the floor within a prescribed accuracy and quickly eliminates unoccupied regions from the search space, and (iii) travels efficiently to collect the required samples for target detection.
