The Safe and Effective Use of Low-Assurance Predictions in Safety-Critical Systems (04b Atto di convegno in volume)

Kunal Agrawal, Sanjoy Baruah, Bender Michael A., MARCHETTI SPACCAMELA Alberto

The algorithm-design paradigm of algorithms using predictions is explored as a means of incorporating the computations of lower-assurance components (such as machine-learning based ones) into safetycritical systems that must have their correctness validated to very high levels of assurance. The paradigm is applied to two simple example applications that are relevant to the real-time systems community: energy-aware scheduling, and classification using ML-based classifiers in conjunction with more reliable but slower deterministic classifiers. It is shown how algorithms using predictions achieve much-improved performance when the low-assurance computations are correct, at a cost of no more than a slight performance degradation even when they turn out to be completely wrong.
