Gamma-Minimax Wavelet Shrinkage with Three-Point Priors
Dixon Vimalajeewa, Brani Vidakovic
In this paper we propose a method for wavelet denoising of signals contaminated with Gaussian noise when prior information about the -energy of the signal is available. Assumi…
Robust Wavelet-based Assessment of Scaling with Applications
Erin K. Hamilton, Seonghye Jeon, Pepa Ramirez Cobo +2
A number of approaches have dealt with statistical assessment of self-similarity, and many of those are based on multiscale concepts. Most rely on certain distributional assumption…
Non-decimated 2D Wavelet Spectrum and Its Use in Breast Cancer Diagnostics
Minkyoung Kang, William Auffermann, Brani Vidakovic
To improve diagnostic accuracy of breast cancer detection, several researchers have used the wavelet-based tools, which provide additional insight and information for aiding diagno…
Bayesian Wavelet Shrinkage with Beta Priors
Alex Rodrigo dos Santos Sousa, Nancy Lopes Garcia, Branislav Vidakovic
In wavelet shrinkage and thresholding, most of the standard techniques do not consider information that wavelet coefficients might be bounded, although information about bounded en…
Least Squares Wavelet-based Estimation for Additive Regression Models using Non Equally-Spaced Designs
German A. Schnaidt Grez, Brani Vidakovic
Additive regression models are actively researched in the statistical field because of their usefulness in the analysis of responses determined by non-linear relationships with mul…
Bayesian nonparametric regression using complex wavelets
Norbert Reményi, Brani Vidakovic
In this paper we propose a new adaptive wavelet denoising methodology using complex wavelets. The method is based on a fully Bayesian hierarchical model in the complex wavelet doma…
