Wavelet-based feature extraction methods for classification applications
Ozhan Duzenli, Monique P. Fargues · 2002
This work discusses feature extraction and dimension-reduction issues in the context of classification applications. A new type of projection pursuit algorithm is presented. This scheme is designed to reduce the number of class features obtained from the wavelet packet decomposition of the signals to be classified. Results show the simple scheme can be used to classify various types of signals in a noisy environment.
