RobustNCL: Robustifying Neuromorphic Continual Learning under Transient Faults with Lightweight Detect-and-Cure Strategy

RobustNCL is a lightweight framework that enhances the reliability of neuromorphic continual learning (NCL) systems against transient hardware faults. It detects faults during weight access from off‑chip memory and cures affected weights using one of three strategies—zero replacement, min/max value, or most‑probable value—storing curing values in radiation‑hardened memory. Experiments on Split MNIST, Split Fashion‑MNIST, Split CIFAR‑10, and Split CIFAR‑100 show that RobustNCL maintains accuracy within 0.5% of fault‑free models and significantly outperforms baseline NCL methods while adding negligible latency and energy overhead.

Exploring the Trade-Off Between Structured Pruning and Fault Tolerance in Deep Neural Networks for Space Applications

The study examines how reducing the width of deep neural networks through structured pruning affects their robustness to Single Event Upsets (SEUs). By iteratively pruning baseline models and conducting fault-injection tests at each stage, the authors find that while pruning increases per-inference sensitivity to bit-flips, the shorter execution time offsets this, lowering the overall SEU probability. Consequently, structured pruning can deliver energy and latency savings without compromising reliability for space-based AI systems.
