NONLINEAR BLIND SOURCE SEPARATION OF MECHANICAL FAULT BASED ON QUANTUM GENETIC ALGORITHM
Jixie qiangdu, 2015 Based on the deficiency in the traditional nonlinear blind separation method of mechanical fault sources,i. e. the separation matrix parameter and nonlinear mixing parameter in the nonlinear blind source separation are usually optimized separately,which ...

Arthritis Care &Research, Accepted Article.Objective We aimed to estimate the prevalence and cumulative incidence of hydroxychloroquine retinopathy (HCQ‐R) and its risk factors among long‐term HCQ users with rheumatic diseases through a systematic review and meta‐analysis of observational studies that used spectral‐domain OCT (SD‐OCT) for screening. Methods A systematic search of PubMed, Scopus,

Stationary Points of a Kurtosis Maximization Criterion for Noisy Blind Source Extraction
IEEE Access, 2017 Blind source extraction (BSE) is often posed as the maximization of a statistical criterion under a unitary constraint. This paper addresses the convergence problem of a kurtosis-based criterion in the presence of noise.

High Healthcare Utilization Preceding Diagnosis with Juvenile Idiopathic Arthritis
Arthritis Care &Research, Accepted Article.Objective Though early diagnosis improves long‐term outcomes, Juvenile Idiopathic Arthritis (JIA) patients often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize healthcare utilization in the year preceding diagnosis.

Denoising Using Blind Source Separation for Pyroelectric Sensors
EURASIP Journal on Advances in Signal Processing, 2001 This paper deals with a process of denoising based on a Blind Source Separation (BSS) method. This technique is inserted in an experimental device of nondestructive testing. Its excitation is a laser beam and its detectors are pyroelectric sensors.

Blind source separation with optimal transport non-negative matrix factorization
EURASIP Journal on Advances in Signal Processing, 2018 Optimal transport as a loss for machine learning optimization problems has recently gained a lot of attention. Building upon recent advances in computational optimal transport, we develop an optimal transport non-negative matrix factorization (NMF ...
