Robust Hyperspectral Unmixing With Correntropy-Based Metric

open access: yesIEEE Transactions on Image Processing, 2015
Hyperspectral unmixing is one of the crucial steps for many hyperspectral applications. The problem of hyperspectral unmixing has proven to be a difficult task in unsupervised work settings where the endmembers and abundances are both unknown. What is more, this task becomes more challenging in the case that the spectral bands are degraded with noise ...

Diffusion Logarithm-Correntropy Algorithm for Parameter Estimation in Non-Stationary Environments over Sensor Networks

open access: yesSensors, 2018
This paper considers the parameter estimation problem under non-stationary environments in sensor networks. The unknown parameter vector is considered to be a time-varying sequence.

A new compensation method for sensor-drift effect based on the cross-correntropy concept

open access: yes, 2011

Fractional time delay estimation method based on the minimum CIM and the Farrow structure

open access: yesTongxin xuebao, 2015
A fractional time delay estimation algorithm is proposed which is based on the minimum CIM and the Farrow structure (referred to as MCIMFarrow).The proposed MCIMFarrow algorithm performs well in symmetric Alpha stable noise conditions.And it needs little

Correntropy coefficients between ΔCVF and BVF (IJVs and VVs) data.

open access: yes, 2013
The interaction between ΔCVF and BVF (IJVs and VVs) for MS group and CTR group behaved almost in the same way at the VVs flow recording, as revealed by the magnitudes of the correntropy coefficients (first and second rows of the table).The variable ΔCVF ...

Variable step-size LMP algorithm based on correntropy induced metric

open access: yes
For the problem of underwater sparse channel estimation under α-stable distributed impulsive noise, correntropy induced metric variable step-size least mean p-power (CVSS-LMP) algorithm was proposed.

Multiplicative Algorithm for Correntropy-Based Nonnegative Matrix Factorization

open access: yes, 2013
Nonnegative matrix factorization (NMF) is a popular dimension reduction technique used for clustering by extracting latent features from highdimensional data and is widely used for text mining.

Correntropy coefficient analysis of fMRI using reference model

open access: yes, 2012
A non-invasive functional MRI (fMRI) has emerged effective in the investigation of the functionality of human brain. However, detection of functional activation is often complicated by the presence of noise. In this paper, we propose an approach based on

Distribution-Aware, Risk-Sensitive (DA-RS-FxNLMS) Active Noise Control for Non-Gaussian Acoustic Environments

open access: yesAcoustics
Active noise control (ANC) in real-world acoustic environments frequently faces impulsive and heavy-tailed noise disturbances, which degrade the performance significantly and lead to slow convergence.
