Parameter-Adaptive TVF-EMD Feature Extraction Method Based on Improved GOA

Parameter-Adaptive TVF-EMD Feature Extraction Method Based on Improved GOA

In order to separate the sub-signals and extract the feature frequency in the signal accurately, we proposed a parameter-adaptive time-varying filtering empirical mode decomposition (TVF-EMD) feature extraction method based on the improved grasshopper optimization algorithm (IGOA). The method not on...
