Improved Bagging Algorithm for Pattern Recognition in UHF Signals of Partial Discharges

Jiang, Tianyan; Li, Jian; Zheng, Yuanbing; Sun, Caixin - In: Energies 4 (2011) 7, pp. 1087-1101

This paper presents an Improved Bagging Algorithm (IBA) to recognize ultra-high-frequency (UHF) signals of partial discharges (PDs). This approach establishes the sample information entropy for each sample and the re-sampling process of the traditional Bagging algorithm is optimized. Four...
