报告摘要:

While complex engineering systems incorporate first principles based on physical models, they may not make full use of relevant information from real-time data. Exclusively data-driven approaches to complex engineering systems may lead to incorrect and uninformed decisions as they do not incorporate useful information from the engineering and physical models. A hybrid approach that uses real-time data, in conjunction with basic physical and engineering constraints, has the promise to overcome these limitations and can lead to significantly improved decision capabilities.

In the first part of this talk, I will present an online nonlinear system identification algorithm that can simultaneously identify local linear models as well as their validity zones with minimum calibration efforts. It is enabled by integrating an online clustering algorithm with recursive least squares. In the second part of this talk, I will present a safe Reinforcement Learning framework where we learn a safe policy safely by exploiting system dynamics for training supervision. It has the great potential to enable real-time learning with safety-critical systems like process control systems. I will also talk about a recent project on AI-enabled apple robotic harvesting.
