Adaptive DCTNet for Audio Signal Classification
Yin Xian, Yunchen Pu, Zhe Gan +2
In this paper, we investigate DCTNet for audio signal classification. Its output feature is related to Cohen's class of time-frequency distributions. We introduce the use of adapti…
The Cascading Haar Wavelet algorithm for computing the Walsh-Hadamard Transform
Andrew Thompson
We propose a novel algorithm for computing the Walsh-Hadamard Transform (WHT) which consists entirely of Haar wavelet transforms. We prove that the algorithm, which we call the Cas…
Compressive imaging using fast transform coding
Andrew Thompson, Robert Calderbank
We propose deterministic sampling strategies for compressive imaging based on Delsarte-Goethals frames. We show that these sampling strategies result in multi-scale measurements wh…
Quantitative recovery conditions for tree-based compressed sensing
Coralia Cartis, Andrew Thompson
As shown in [Blumensath and Davies 2009, Baraniuk et al. 2010], signals whose wavelet coefficients exhibit a rooted tree structure can be recovered using specially-adapted compress…
DCTNet and PCANet for acoustic signal feature extraction
Yin Xian, Andrew Thompson, Xiaobai Sun +2
We introduce the use of DCTNet, an efficient approximation and alternative to PCANet, for acoustic signal classification. In PCANet, the eigenfunctions of the local sample covarian…
