ADMM for maximum correntropy criterion [PDF]

open access: yes2016 International Joint Conference on Neural Networks (IJCNN), 2016
The correntropy provides a robust criterion for outlier-insensitive machine learning, and its maximisation has been increasingly investigated in signal and image processing. In this paper, we investigate the problem of unmixing hyperspectral images, namely decomposing each pixel/spectrum of a given image as a linear combination of other pixels/spectra ...

Complex Correntropy with Variable Center: Definition, Properties, and Application to Adaptive Filtering

open access: yesEntropy, 2020
The complex correntropy has been successfully applied to complex domain adaptive filtering, and the corresponding maximum complex correntropy criterion (MCCC) algorithm has been proved to be robust to non-Gaussian noises.

Correntropy based Robust Decomposition of Neuromodulations [PDF]

open access: yes2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019
Neuromodulations as observed in the extracellular electrical potential recordings obtained from Electroencephalograms (EEG) manifest as organized, transient patterns that differ statistically from their featureless noisy background. Leveraging on this statistical dissimilarity, we propose a noniterative robust classification algorithm to isolate, in ...

State estimation for dynamic systems with higher-order autoregressive moving average non-Gaussian noise

open access: yesFrontiers in Energy Research, 2022
The classical Kalman filter is a very important state estimation approach, which has been widely used in many engineering applications. The Kalman filter is optimal for linear dynamic systems with independent Gaussian noises.

Local Matrix Feature-Based Kernel Joint Sparse Representation for Hyperspectral Image Classification

open access: yesRemote Sensing, 2022
Hyperspectral image (HSI) classification is one of the hot research topics in the field of remote sensing. The performance of HSI classification greatly depends on the effectiveness of feature learning or feature design. Traditional vector-based spectral–

Generalized Correntropy for RobustAdaptive Filtering [PDF]

open access: yesIEEE Transactions on Signal Processing, 2016
As a robust nonlinear similarity measure in kernel space, correntropy has received increasing attention in domains of machine learning and signal processing. In particular, the maximum correntropy criterion (MCC) has recently been successfully applied in robust regression and filtering. The default kernel function in correntropy is the Gaussian kernel,

Correntropy based Granger causality [PDF]

open access: yes2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
We propose a novel nonlinear extension to Granger causality. It is derived from a nonlinear mapping of a stochastic process using the recently introduced generalized correlation measure called correntropy. The method is demonstrated by detecting the direction of coupling in a chaotic system where the original Granger causality failed.

Evolved-Cooperative Correntropy-Based Extreme Learning Machine for Robust Prediction

open access: yesEntropy, 2019
In recent years, the correntropy instead of the mean squared error has been widely taken as a powerful tool for enhancing the robustness against noise and outliers by forming the local similarity measurements.

Two-Channel Information Fusion Weak Signal Detection Based on Correntropy Method

open access: yesApplied Sciences, 2022
In recent years, as a simple and effective method of noise reduction, singular value decomposition (SVD) has been widely concerned and applied. The idea of SVD for denoising is mainly to remove singular components (SCs) with small singular value (SV ...
