Selective ensemble modeling load parameters of ball mill based on multi-scale frequency spectral features and sphere criterion
The ball mill shell vibration and acoustical signals are adaptively decomposed. A new adaptive multi-scale spectral feature selection approach is proposed. The feature selection parameters of candidate sub-models are selected simultaneously. The single-scale frequency spectrum model is extended to multi-scale frequency spectra.
