ShardNet: Training Neural Controllers with Hard, Non-Convex Constraints

arXiv:2606.30935v1 Announce Type: cross Abstract: While neural network control policies are powerful, their deployment on safety critical systems depends on ensuring that they obey strict constraints. Existing work often treats safety as a metric to optimize for, which competes with other performance objectives, if training converges at all. Instead, we introduce ShardNet, a neural network architecture that strictly enforces unions of polyhedral constraints by construction, using a differentiable projection layer parameterized by a classification network. The key insight is to embed safety int

Why this matters
Why now

The increasing complexity of AI systems, particularly in safety-critical applications, necessitates robust methods for constraint enforcement, making this development timely for real-world deployment.

Why it’s important

This development addresses a fundamental limitation in deploying AI in sensitive domains by guaranteeing adherence to safety constraints, which is crucial for public trust and regulatory acceptance.

What changes

Neural network controllers can now be designed from the ground up to strictly obey hard, non-convex constraints, moving beyond optimization-based approaches that offer no such guarantees.
