Learning to Keep Systems Safe Without Knowing How They Work

01.02.2026 by Ray Dalio

A safety filter, learned solely from system transitions, employs a safety critic to map states and constraints to safety valuations and their derivatives, which then inform a quadratic programming solver-in conjunction with initial reference inputs-to generate demonstrably safe control actions, as evidenced by its ability to stabilize an inherently unstable system even when subjected to aggressive [latex] \pm 1 [/latex] reference commands.

A new data-driven approach enables safe control of complex systems, even when their internal dynamics are unknown.
