Machine learning models achieve remarkable performance when large amounts of training data are available. However, data is often limited for many real-world systems such as biological systems and space exploration robots. Additionally, many real-world systems are safety-critical, and learning-based models usually do not exhibit safety guarantees, especially for out-of-distribution data.

In this talk, I will introduce provably safe reinforcement learning (RL) approaches that ensure hard safety guarantees for RL both during training and deployment by leveraging formal methods. In particular, we will discuss a safeguard for nonlinear system dynamics in dynamic environment that ensures collision avoidance, and continuous action masking that leverages domain knowledge encoded in convex action sets to focus RL exploration.
