The design of matching pursuit filters

Network: Computation in Neural Systems, 1998
This paper presents a new technique for creating efficient and compact models from data, called matching pursuit filters. The design of a matching pursuit filter is based on an adapted wavelet expansion, where the expansion is adapted to both the data and the pattern recognition problem being addressed.

Covariance-Assisted Matching Pursuit

IEEE Signal Processing Letters, 2016
We consider the problem of greedy sparse approximation in the presence of noise, given a-priori knowledge of the sparse coefficients’ covariance and mean. The proposed Covariance-Assisted Matching Pursuit (CAMP) combines the a-priori knowledge by leveraging the Gauss-Markov theorem, and provides significantly better performance than the classical ...

Online search Orthogonal Matching Pursuit

2012 IEEE Statistical Signal Processing Workshop (SSP), 2012
The recovery of a sparse signal x from y= Φx, where Φ is a matrix with more columns than rows, is a task central to many signal processing problems. In this paper we present a new greedy algorithm to solve this type of problem. Our approach leverages ideas from the field of online search on state spaces.

Distortion of Matching Pursuit: Modeling and Optimization

Data Compression Conference (DCC'06), 2006
Summary form only given. The distortion of matching pursuit is expressed in terms of MP encoder parameters for uniformly distributed signals and dictionaries. Under certain conditions, the distortion caused by matching pursuit decomposition of the signal can be calculated in terms of the norm of the signal, signal dimension, dictionary size, and the ...

In Pursuit of a ‘Good’ Match

2020
The fixation of finding a ‘good match’ was famously described in Vikram Seth’s A Suitable Boy (1993). A narrative of post-partition India, the novel revolves around Rupa Mehra’s obsession of finding a suitable spouse for her youngest daughter Lalita, from amongst four ‘candidates’ or prospective grooms.
