Cross-condition and cross-platform remaining useful life estimation via adversarial-based domain adaptation [PDF]
Supervised machine learning is a traditionally remaining useful life (RUL) estimation tool, which requires a lot of prior knowledge. For the situation lacking labeled data, supervised methods are invalid for the issue of domain shift in data distribution.
