Ghavamipour, Ali Reza (author), Turkmen, Fatih (author), Wang, Rui (author), Liang, K. (author)Synthetic data generation plays a crucial role in many areas where data is scarce and privacy/confidentiality is a significant concern. Generative Adversarial Networks (GANs), arguably one of the most widely used data synthesis techniques, allow for the training of a model (i.e., generator) that can generate real-looking data by playing a min...conference paper 2023

Du, D. (author), Han, S. (author), Qi, Naiming (author), Ammar, Haitham Bou (author), Wang, Jun (author), Pan, W. (author)Reinforcement learning (RL) exhibits impressive performance when managing complicated control tasks for robots. However, its wide application to physical robots is limited by the absence of strong safety guarantees. To overcome this challenge, this paper explores the control Lyapunov barrier function (CLBF) to analyze the safety and reachability...conference paper 2023

Wang, Weiying (author), Kemmeren, A.C. (author), Son, Daniel (author), Alonso-Mora, J. (author), Gil, Stephanie (author)In this paper we propose a novel algorithm, Wi-Closure, to improve the computational efficiency and robustness of loop closure detection in multi-robot SLAM. Our approach decreases the computational overhead of classical approaches by pruning the search space of potential loop closures, prior to evaluation by a typical multi-robot SLAM pipeline....conference paper 2023

Balim, Haldun (author), Park, Seonwook (author), Wang, Xi (author), Zhang, X. (author), Hilliges, Otmar (author)Despite the recent development of learning-based gaze estimation methods, most methods require one or more eye or face region crops as inputs and produce a gaze direction vector as output. Cropping results in a higher resolution in the eye regions and having fewer confounding factors (such as clothing and hair) is believed to benefit the final...conference paper 2023
