Motivated by Chernoff’s bound on asymptotic probability of error we propose the alpha-divergence measure and a surrogate, the alpha-Jensen difference, for feature classification, indexing and retrieval in image and other databases. The alpha-divergence, also known as Renyi divergence, is a generalization of the Kullback-Liebler divergence and the Hellinger affinity between the probability densi...

The α-stable family of distributions constitutes a generalization of theGaussian distribution, allowing for asymmetry and thicker tails. Its practicalusefulness is coupled with a marked theoretical appeal, given that it stemsfrom a generalized version of the central limit theorem in which the assump-tion of the finiteness of the variance is replaced by a much less restrictiv...

Real-time estimation of weld quality from process data is one of the key objectives in current weld control systems for resistance spot-welding processes. This task can be alleviated if the weld controller is equipped with a voltage sensor in the secondary circuit. Replacing the goal of quantifying the weld quality in terms of button size by the more modest objective of indirect estimation of t...

Background: Human resources are considered the most valuable capital of every healthcare system, and the quality of care is closely related to the quantity and skill of this group. Therefore, the proper estimation of the required nursing staff in different wards can help improve the quality of nursing care. The purpose of this study was to determine the hours of provided care by nursing staff i...
