Two pervasive issues compromise prediction fidelity: (1) domain heterogeneity caused by batch\u2011to\u2011batch variations, and (2) non\u2011monotonic capacity regeneration events. This talk focuses on our dual contributions: a robust transfer\u2011learning ensemble that leverages early\u2011cycle kernel regression with domain\u2011distance-based weighting and transfer component analysis for cross\u2011batch alignment; and a monotone decomposition technique that segregates the capacity signal into a monotonically decreasing component and a regeneration term, each forecasted via Gaussian processes and deep autoregression for uncertainty\u2011aware RUL estimates. Results on multiple datasets demonstrate the efficacy of our approaches in real\u2011world scenarios.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"765\">\nDr. Piao Chen is currently an associate professor at the ZJU-UIUC Institute, Zhejiang University.
