Efficient Motion Planning for Manipulators with Control Barrier Function-Induced Neural Controller

no code implementations1 Apr 2024 Mingxin Yu, Chenning Yu, M-Mahdi Naddaf-Sh, Devesh Upadhyay, Sicun Gao, Chuchu Fan

Our method combines the strength of CBF for real-time collision-avoidance control and RRT for long-horizon motion planning, by using CBF-induced neural controller (CBF-INC) to generate control signals that steer the system towards sampled configurations by RRT.

Targeted collapse regularized autoencoder for anomaly detection: black hole at the center

no code implementations22 Jun 2023 Amin Ghafourian, Huanyi Shui, Devesh Upadhyay, Rajesh Gupta, Dimitar Filev, Iman Soltani Bozchalooi

In practice, however, it is observed that autoencoders can generalize beyond the normal class and achieve a small reconstruction error on some of the anomalous samples.

FIR-based Future Trajectory Prediction in Nighttime Autonomous Driving

1 code implementation31 Mar 2023 Alireza Rahimpour, Navid Fallahinia, Devesh Upadhyay, Justin Miller

In order to minimize false collision warnings, in our multi-step framework, first, the large animal is accurately detected and a preliminary risk level is predicted for it and low-risk animals are discarded.
