AMP: Assembly Matching Pursuit

Factorization of Overlapping Harmonic Sounds Using Approximate Matching Pursuit

Factorization of polyphonic musical signals remains a difficult problem due to the presence of overlapping harmonics. Existing dictionary learning methods cannot guarantee that the learned dictionary atoms are semantically meaningful. In this paper, we explore the factorization of harmonic musical signals when a fixed dictionary of harmonic sounds is already present. We propose a method called ...

Adaptive matching pursuit with constrained total least squares

Compressive sensing (CS) can effectively recover a signal when it is sparse in some discrete atoms. However, in some applications, signals are sparse in a continuous parameter space, e.g., frequency space, rather than discrete atoms. Usually, we divide the continuous parameter into finite discrete grid points and build a dictionary from these grid points. However, the actual targets may not exa...

PMU-Based Matching Pursuit Method for Black-Box Modeling of Synchronous Generator

This paper presents the application of the matching pursuit method to model synchronous generator. This method is useful for online analysis. In the proposed method, the field voltage is considered as input signal, while the terminal voltage and active power of the generator are output signals. Usually, the difference equation with a second degree polynomial structure is used to estimate the co...

Optimizing DSP and media benchmarks for Pentium 4: hardware and software issues

By examining the speed-up resulting from using SIMD instructions for DSP kernels (FFT) and two different multimedia programs (MPEG2 and a Matching Pursuit video codec), we discuss the hardware and software issues that limit performance. Some features in present implementation of Intel SIMD instructions limit the efficiency of dot products. C programmer’s habits also complicate the compiler task...
