Widely Linear Quaternion-Valued Least-Mean Kurtosis Algorithm [PDF]
IEEE Transactions on Signal Processing, 2020 A widely linear quaternion-valued least-mean kurtosis (WL-QLMK) algorithm is introduced for adaptive filtering of quaternion-valued circular and noncircular signals. In the design, kurtosis-based cost function is first defined in the quaternion domain by integrating the widely linear model, and augmented statistics, and then minimized using the ...

Spatiotemporal dynamics of diffusional kurtosis, mean diffusivity and perfusion changes in experimental stroke [PDF]
Brain Research, 2012 Diffusional kurtosis imaging (DKI), which measures the non-Gaussianity of water diffusion, has been demonstrated to be a sensitive biomarker in many neuropathologies. The goal of this study was to longitudinally examine the spatiotemporal dynamics of DKI in cerebral ischemia in an animal model of permanent and transient (45 min) middle cerebral artery ...

Sparsity-aware complex-valued least mean kurtosis algorithms [PDF]
Signal ProcessingComplex-valued least mean kurtosis (CLMK) algorithm and its augmented version (ACLMK) have recently become popular as workhorse tools in the processing of complex-valued signals due to their superior performances. Unfortunately, they are not yet suitable for sparse system identification problems.

An Augmented Complex-Valued Least-Mean Kurtosis Algorithm for the Filtering of Noncircular Signals [PDF]
IEEE Transactions on Signal Processing, 2018 In this paper, a novel augmented complex-valued least-mean kurtosis (ACLMK) algorithm is proposed for processing complex-valued signals. The negated kurtosis of the complex-valued error signal is defined as a cost function by using augmented statistics.

Experimentally and computationally fast method for estimation of a mean kurtosis
Magnetic Resonance in Medicine, 2013AbstractPurposeResults from several recent studies suggest the magnetic resonance diffusion‐derived metric mean kurtosis (MK) to be a sensitive marker for tissue pathology; however, lengthy acquisition and postprocessing time hamper further exploration.
