Stochastic Expansions in an Overcomplete Wavelet Dictionary
We consider random functions defined in terms of members of an overcomplete wavelet dictionary. The function is modelled as a sum of wavelet components at arbitrary positions and scales where the locations of the wavelet components and the magnitudes of their coefficients are chosen with respect to a marked Poisson process model. The relationships between the parameters of the model and the par...
متن کاملLearning an Overcomplete Dictionary using a Cauchy Mixture Model for Sparse Decay
An algorithm for learning an overcomplete dictionary using a Cauchy mixture model for sparse decomposition of an underdetermined mixing system is introduced. The mixture density function is derived from a ratio sample of the observed mixture signals where 1) there are at least two but not necessarily more mixture signals observed, 2) the source signals are statistically independent and 3) the s...
متن کاملCompressed Sensing Using Adaptive Wavelet Transform and Overcomplete Dictionary
In this paper, we present a new compressed sensing implementation process for one dimension signal reconstruction. Firstly, one level wavelet decomposition of the one dimensional signal was finished. For using the adaptive wavelet transform based on lifting wavelet transforms, we can achieve the detail signals being zero (or almost zero) at big probability, so the signal has the better linear a...

Overcomplete Dictionary Design by Empirical Risk Minimization
Recently, there have been a growing interest in application of sparse representation for inverse problems. Most studies concentrated in devising ways for sparsely representing a solution using a given prototype overcomplete dictionary. Very few studies have addressed the more challenging problem of construction of an optimal overcomplete dictionary, and even these were primarily devoted to the ...
