Towards Implementing ML-Based Failure Detectors

Abstract: Most existing failure detection algorithms rely on statistical methods, and very few use ML. This paper explores the viability of ML in the field of failure detection: is it possible to implement an ML-based detector that achieves a satisfactory quality of service? We implement a prototype that uses a basic long short-term memory neural network algorithm, and study its behavior with real traces. Although ML model has comparatively longer computing time, our prototype performs well in terms of accuracy and detection time.
