Selective Noise Cancellation Using Independent Component Analysis

​Rank based Least-squares Independent Component Analysis

  In this paper, we propose a nonparametric rank-based alternative to the least-squares independent component analysis algorithm developed. The basic idea is to estimate the squared-loss mutual information, which used as the objective function of the algorithm, based on its copula density version. Therefore, no marginal densities have to be estimated. We provide empirical evaluation of th...

Adaptive Noise Canceling Using Convolved Reference Noise Based on Independent Component Analysis

This paper presents adaptive noise canceling(ANC) using convolved reference noise. In many practical ANC applications, the reference noise has channel distortion, which may degrade its performance. If the distortion includes nonminimum-phase parts, the inverse cannot be implemented as a causal filter. Therefore, the conventional ANC system may not provide a satisfactory performance. In this pap...

Efficiency Measurement of Clinical Units Using Integrated Independent Component Analysis-DEA Model under Fuzzy Conditions

Background and Objectives: Evaluating the performance of clinical units is critical for effective management of health settings. Certain assessment of clinical variables for performance analysis is not always possible, calling for use of uncertainty theory. This study aimed to develop and evaluate an integrated independent component analysis-fuzzy-data envelopment analysis approach to accurate ...

Independent Component Analysis in the presence of Gaussian Noise

The problem of estimating the statistical model of independent component analysis in the presence of Gaussian noise is considered. Because of the additive noise, a combination of factor analysis and a noise-free ICA algorithm doesn't give a consistent estimator of the mixing matrix. In this paper, following the semiparametric statistical approach to the noise-free ICA model by Amari and Cardoso...
