CCI, AAI, and MHI Joint Seminar Series - Radoslav Ivanov (Rensselaer Polytechnic Institute): Safe and secure autonomy within reach: a verified machine learning and control perspective
Tue, Feb 13, 2024 @ 02:00 PM - 03:00 PM

Speaker: Radoslav Ivanov, Rensselaer Polytechnic Institute
Talk Title: Safe and secure autonomy within reach: a verified machine learning and control perspective
Abstract: In this talk, I will present an integrated approach to assuring the safety and security of cyber-physical systems (CPS) through a combination of offline verification and online monitoring techniques. For offline assurance, I have developed an approach, called Verisig, for verifying the safety of autonomous systems with neural network controllers. I will present an exhaustive evaluation on a neural-network-controlled (1/10-scale) autonomous racing car, in terms of modeling, verification and experiments on the real platform. In the second part of the talk, I will describe my work on run-time monitoring of system safety, with applications to medical CPS. Specifically, I will present a detector for critical drops in the patient's oxygen content during surgery, with guaranteed performance regardless of varying physiological parameters such as metabolism. The detector is evaluated on real-patient data collected from the Children's Hospital of Philadelphia.

Biography: Radoslav Ivanov He is an Assistant Professor in Computer Science at the Rensselaer Polytechnic Institute. Prior to that, he was a postdoc at the PRECISE center at the University of Pennsylvania. Radoslav received the B.A. degree in computer science and economics from Colgate University in 2011, and the Ph.D. degree in computer and information science from the University of Pennsylvania in 2017. His research interests are broadly in the field of safe and secure autonomy, with a focus on verified machine learning, control theory and cyber-physical security. The natural application domains of his work are automotive and medical cyber-physical systems.

CS Colloquium: Parastoo Abtahi (Princeton University) - From Haptic Illusions to Beyond Real Interactions in Virtual Reality
Wed, Feb 14, 2024 @ 02:00 PM - 03:00 PM

Speaker: Parastoo Abtahi, Princeton University
Talk Title: From Haptic Illusions to Beyond Real Interactions in Virtual Reality
Abstract: Advances in audiovisual rendering have led to the commercialization of virtual reality (VR) hardware; however, haptic technology has not kept up with these advances. While haptic devices aim to bridge this gap by simulating the sensation of touch, many hardware limitations make realistic touch interactions in VR challenging. In my research, I explore how by understanding human perception, we can design VR interactions that not only overcome the current limitations of VR hardware but also extend our abilities beyond what is possible in the real world. In this talk, I will present my work on redirection illusions that leverage the limits of human perception to improve the perceived performance of encountered-type haptic devices, such as improving the position accuracy of drones, the speed of tabletop robots, and the resolution of shape displays when used for haptics in VR. I will then present a framework I have developed through the lens of sensorimotor control theory to argue for the exploration and evaluation of VR interactions that go beyond mimicking reality.
