Discriminant Independent Component Analysis
IEEE Transactions on Neural Networks, 2009A conventional linear model based on Negentropy maximization extracts statistically independent latent variables which may not be optimal to give a discriminant model with good classification performance. In this paper, a single-stage linear semisupervised extraction of discriminative independent features is proposed. Discriminant independent component

Independent component analysis and beyond
Signal Processing, 2004Independent component analysis (ICA) aims at extracting unknown hidden factors/components from multivariate data using only the assumption that the unknown factors are mutually independent. Since the introduction of ICA concepts in the early 1980s in the context of neural networks and array signal processing, many new successful algorithms have been ...

Multilinear Independent Components Analysis
2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2005Independent components analysis (ICA) maximizes the statistical independence of the representational components of a training image ensemble, but it cannot distinguish between the different factors, or modes, inherent to image formation, including scene structure, illumination, and imaging.

Compressive Independent Component Analysis
2019 27th European Signal Processing Conference (EUSIPCO), 2019In this paper we investigate the minimal dimension statistic necessary in order to solve the independent component analysis (ICA) problem. We create a compressive learning framework for ICA and show for the first time that the memory complexity scales only quadratically with respect to the number of independent sources n, resulting in a vast ...

Research of independent component analysis
2004 IEEE International Conference on Systems, Man and Cybernetics (IEEE Cat. No.04CH37583), 2005Independent component analysis (ICA) is a statistical technique to decompose multivariate data into statistically independent components. It could be applied to mine data of medical, economy or telecommunication systems, and to analyze data of GIS systems for agriculture or environment applications. To solve the problem of blind source separation, this

Least-Squares Independent Component Analysis
Neural Computation, 2011Accurately evaluating statistical independence among random variables is a key element of independent component analysis (ICA). In this letter, we employ a squared-loss variant of mutual information as an independence measure and give its estimation method.

Multidimensional independent component analysis
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002This paper proposes to generalize the notion of independent component analysis (ICA) to the notion of multidimensional independent component analysis (MICA). We start from the ICA or blind source separation (BSS) model and show that it can be uniquely identified provided it is properly parameterized in terms of one-dimensional subspaces.
