Mathematical Mechanism of Gini Index Used for Multiple-Impulse Phenomenon Characterization
The Gini index (GI) is widely used for measuring the sparsity of signals and has been proven to be effective in the extraction of fault features. A fault-induced vibration, which involves the obvious phenomenon of multiple impulses, is a kind of sparse signal and the GI has been widely used in the d...
