Abstract:A novel nonlinear collaborative modeling method for remaining useful life (RUL) prediction is proposed. This method uses a kernel-based Wiener process (KWP) model, which formulates a nonlinear drift function with the weighted combination of kernel functions. Compared with the existing Wiener process models, this kind of modeling allows characterizing the nonlinearity of degradation more accurately and flexibly. To address the problem of error accumulation and lack of data in long-term prediction, a transfer le… Show more
