We also illustrate several audio applications of sparse atomic modeling. 1. INTRODUCTION Many natural signals can be sparsely represented (or sparsely ap-proximated) if an appropriate basis can be found. For example, a short block of samples from a quasi-periodic sound will have a sparse Fourier transform if the block size is a multiple of the pitch

Agglomerative clustering in sparse atomic decompositions of audio signals (2008) by B L Sturm, J J Shynk, S Gauglitz ... and reviews recent work in the application of such methods to working with audio and music signals. As Fourier analysis is to additive synthesis, DBMs can be seen as the analytical counterpart to a generalized granular ...

use DE to improve the sparse atomic estimation of signals. The rest of this paper is organized as follows. Section II provides an overview of a sparse signal model and briefly reviews MP. In Section III, we present a formal measure of DE and discuss its significance. Section IV presents some empirical results for a set of real audio signals ...

Zhangyang Wang, in Deep Learning Through Sparse and Low-Rank Modeling, 2019. 3.1 Introduction. Sparse signal approximation has gained popularity over the last decade. The sparse approximation model suggests that a natural signal could be compactly approximated by only a few atoms out of a properly given dictionary, where the weights associated with the dictionary …
