Time-scale wavelet scattering using hyperbolic tangent function for vessel sound classification

Can, Gökmen; Akbaş, Cem Emre; Çetin, A. Enis (IEEE, 2017-08-09)

We introduce a time-frequency scattering method using hyperbolic tangent function for vessel sound classification. The sound data is wavelet transformed using a two channel filter-bank and filter-bank outputs are scattered ...
Use of time-frequency representations in the analysis of stock market data

Sayan, G. T.; Sayan, Serdar (Springer, 2002)

The analysis of economic/financial time series in the frequency domain is a relatively underexplored area of the literature, particularly when the statistical properties of a time series are time-variant (evolutionary). ...
