Wavelet Thresholding for Non (Necessarily) Gaussian Noise
… coefficients. <br>In the second approach the risk of an estimator is compared to the risk of <br>an ``ideal'' estimator. This ``estimator'' is ``ideal'' because it has some <br>knowledge of the wavelet coefficients of the function to estimate, so it is <br>not really an estimator. <br>The …

l0 Sparse signal processing and model selection with applications
… commonly used model selection methods, the SURE (Stein's unbiased risk estimator) estimator stands out as one which does not suffer from the limitations of other methods. Most model selection criterion are developed based on signal or prediction mean squared error. The last section of this thesis …

Simultaneous estimation approaches to large-scale multivariate regression
Large-scale multivariate regression has various applications in machine learning fields, especially in image recognition, gene expression prediction and multivariate time series prediction. Numerous approaches have been developed to solve this problem. Some popular statistical methods are group …
