Smart Mobility Connection Seminar
April 21 @ 12:30 pm - 1:30 pm
Our last Smart Mobility Connection of spring semester on Friday, April 21 from 12:30 – 1:30 PM eastern. Yorie Nakahira, Assistant Professor, Electrical and Computer Engineering at Carnegie Mellon University will speak on her work, Safety of Intelligent Systems Operating in Uncertain and Interactive Environments.
Autonomous systems using learning-based techniques must safely operate in uncertain and interactive environments. One aspect of safe decision-making is accounting for strategic human behavior, which can exploit conservative safe control methods and result in greater risks. We propose a framework to investigate these situations and suggest rethinking safe control methods. Another critical aspect is dealing with latent risks and extreme situations. We introduce a probabilistic safety certificate that mediates behaviors based on latent risks and interaction models. The certificate guarantees long-term safety and allows multiple agents to ensure system-wide safety specifications despite limited communication. Finally, we show that physics-informed neural networks can be used to efficiently estimates long-term risk probabilities using samples of shorter-term trajectories and do so with theoretical guarantees. Such risk quantification methods can be useful in many safe control and learning techniques.
