Natural gradient works efficiently in learning

SI Amari - Neural computation, 1998 - ieeexplore.ieee.org
When a parameter space has a certain underlying structure, the ordinary gradient of a
function does not represent its steepest direction, but the natural gradient does. Information …

Blind beamforming for non-Gaussian signals

JF Cardoso, A Souloumiac - IEE proceedings F (radar and signal processing), 1993 - IET
The paper considers an application of blind identification to beamforming. The key point is to
use estimates of directional vectors rather than resort to their hypothesised value. By using …

A fast fixed-point algorithm for independent component analysis

A Hyvärinen, E Oja - Neural computation, 1997 - direct.mit.edu
We introduce a novel fast algorithm for independent component analysis, which can be used
for blind source separation and feature extraction. We show how a neural network learning …

Equivariant adaptive source separation

JF Cardoso, BH Laheld - IEEE Transactions on signal …, 1996 - ieeexplore.ieee.org
Source separation consists of recovering a set of independent signals when only mixtures
with unknown coefficients are observed. This paper introduces a class of adaptive …

Blind separation of sources: Methods, assumptions and applications

A Mansour, AK Barros, N Ohnishi - IEICE Transactions on …, 2000 - search.ieice.org
The blind separation of sources is a recent and important problem in signal processing.
Since 1984, it has been studied by many authors whilst many algorithms have been …

Blind source separation based on time-frequency signal representations

A Belouchrani, MG Amin - IEEE transactions on signal …, 1998 - ieeexplore.ieee.org
Blind source separation consists of recovering a set of signals of which only instantaneous
linear mixtures are observed. Thus far, this problem has been solved using statistical …

Blind separation of mixture of independent sources through a quasi-maximum likelihood approach

DT Pham, P Garat - IEEE transactions on Signal Processing, 1997 - ieeexplore.ieee.org
We propose two methods for separating mixture of independent sources without any precise
knowledge of their probability distribution. They are obtained by considering a maximum …

Source separation in post-nonlinear mixtures

A Taleb, C Jutten - IEEE Transactions on signal Processing, 1999 - ieeexplore.ieee.org
We address the problem of separation of mutually independent sources in nonlinear
mixtures. First, we propose theoretical results and prove that in the general case, it is not …

Adaptive blind separation of independent sources: a deflation approach

N Delfosse, P Loubaton - Signal processing, 1995 - Elsevier
In this paper, we address the adaptive blind source separation of independent sources
using higher order statistics. Although this problem was considered in numerous works …
