• abstract = "Stemming from complex mechanisms and working conditions of bearings, single degradation models often fail to adequately describe complex degradation process and provide reliable prediction of remaining useful life (RUL). To address this challenge, an adaptive two-stage degradation framework based on Gaussian process regression (GPR) is proposed. This framework dynamically selects the appropriate degradation model based on the observed characteristics of the actual degradation data, resulting in improved prediction accuracy and adaptability. In the process of constructing the degradation model, the suitable detection method is adaptively determined based on change point locations, facilitating real-time monitoring of degradation pattern shifts. Within the two-stage GPR model, matched kernel functions are chosen based on degradation rate and trend changes, and a degradation indicator is constructed using the genetic programming algorithm. This indicator serves as target set for the GPR model to accurately estimate RUL. The reliability of the proposed method is validated through comparison with other alternative models on prognostics and health management (PHM) challenge bearing datasets, confirming its effectiveness, robustness, and superiority.",
