DOI: 10.1080/00949655.2020.1739286
Abstract: For the analysis of high-dimensional data, regularization methods based on penalized likelihood have been extensively studied over the last few decades. But, they commonly require the optimal choice of tuning parameters to select relevant variables.… read more here.

DOI: 10.1109/access.2022.3215082
Abstract: One of today’s inspiring issues is the 2D histogram-based multilevel threshold selection which is used for segmenting images into several regions. The image analysis warrants exploration of multiclass thresholding techniques using various entropy-based objective functions.… read more here.

DOI: 10.1111/biom.13048
Abstract: Thresholding is a regularization method commonly used for covariance estimation, which provides consistent estimators if the population covariance satisfies certain sparsity condition (Bickel and Levina, 2008a; Cai and Liu, 2011). However, the performance of the… read more here.
