Time-Frequency Localization Deep Neural NetworksConvolutional Neural NetworksSpeech RecognitionMaxoutDropoutIn this paper, a CNN-based structure for the time-frequency localization of information is proposed for Persian speech recognition. Research has shown that the receptive fields' spectrotemporal plasticity...
Time-frequency localization operators are a quantization procedure that maps symbols on to operators and depends on two window functions. We study the range of this quantization and its dependence on the window functions. If the If the short-time Fourier transform of the windows does not have any...
Time-frequency localization operators of Cohen's class. Summary: A technique of producing signals whose energy is concentrated in a given region of the time-frequency plane is examined. The degree to which a particular signal is concentrated is measured by integrating a time- frequency distri......

In this chapter, we consider properties that are related to the geometry of the WD and to the TF localization of a space. For example, we study the relation between the orthogonality of two spaces and the TF disjointness of their WDs. We introduce a distinction between "simple" and "...

We study functions whose time-frequency content are concentrated in a compact region in phase space using time-frequency localization operators as a main tool. We obtain approximation inequalities for such functions using a finite linear combination of eigenfunctions of these operators, as well as a ...
