PAC-Bayesian Certificates for Quadratic Closed-Loop Control

arXiv:2606.28281v1 Announce Type: cross Abstract: PAC-Bayesian bounds provide finite-sample guarantees for data-dependent randomized predictors, but applying them to learning-based control is difficult because the natural objective is a quadratic trajectory cost. Such losses are unbounded, non-Lipschitz , and lead to response-dependent Chernoff terms. We employ System Level Synthesis parameterization, which exposes the closed-loop trajectory map of a linear system directly and makes the quadratic control loss amenable to explicit certification. Moreover, we provide a set of PAC-Bayes-Chernoff

Why this matters
Why now

The increasing complexity and safety requirements of AI in real-world physical systems necessitate more robust methods for certifying performance and safety, moving beyond simulations to guaranteed operational stability.

Why it’s important

This development offers a pathway to provable guarantees for AI-controlled systems, crucial for deployment in high-stakes environments where failures are unacceptable, bridging the gap between theoretical AI and real-world application.

What changes

The ability to formally certify the performance of complex AI control systems with statistical bounds changes the paradigm from 'good enough' to 'guaranteed', potentially accelerating adoption in critical infrastructure and robotics.

Winners
  • · Autonomous systems developers
  • · Robotics industry
  • · Aerospace and defense
  • · Critical infrastructure operators
Losers
  • · Developers relying solely on empirical testing
  • · Industries with low safety standards
  • · Non-certified AI control systems
Second-order effects
Direct

Increased trust and adoption of AI in safety-critical control applications due to verifiable performance guarantees.

Second

New regulatory frameworks and certification bodies will emerge to validate and oversee PAC-Bayesian certified AI systems.

Third

The methodology could extend to other complex AI domains, leading to a broader era of provably safe and reliable AI across various sectors.
