Human-in-the-Loop Optimization of Shared Autonomy in Assistive Robotics. [PDF]

IEEE Robot Autom Lett, 2017
In this paper, we propose a mathematical framework which formalizes user-driven customization of shared autonomy in assistive robotics as a nonlinear optimization problem. Our insight is to allow the end-user, rather than relying on standard optimization techniques, to perform the optimization procedure, thereby allowing us to leave the exact nature of

Human-in-the-Loop Optimization for Deep Stimulus Encoding in Visual Prostheses. [PDF]

Adv Neural Inf Process Syst, 2023
Neuroprostheses show potential in restoring lost sensory function and enhancing human capabilities, but the sensations produced by current devices often seem unnatural or distorted. Exact placement of implants and differences in individual perception lead to significant variations in stimulus response, making personalized stimulus optimization a key ...
