Independent Component Analysis Based on Information Bottleneck

open access: yesAbstract and Applied Analysis, 2015
The paper is mainly used to provide the equivalence of two algorithms of independent component analysis (ICA) based on the information bottleneck (IB). In the viewpoint of information theory, we attempt to explain the two classical algorithms of ICA by ...

Non-independent component analysis

open access: yesThe Annals of Statistics
A seminal result in the ICA literature states that for $AY = \varepsilon$, if the components of $\varepsilon$ are independent and at most one is Gaussian, then $A$ is identified up to sign and permutation of its rows (Comon, 1994). In this paper we study to which extent the independence assumption can be relaxed by replacing it with restrictions on ...

Knowledge-guided multi-scale independent component analysis for biomarker identification

open access: yesBMC Bioinformatics, 2008
Background Many statistical methods have been proposed to identify disease biomarkers from gene expression profiles. However, from gene expression profile data alone, statistical methods often fail to identify biologically meaningful biomarkers related ...

Independent Component Analysis (ICA) based-clustering of temporal RNA-seq data. [PDF]

open access: yesPLoS ONE, 2017
Gene expression time series (GETS) analysis aims to characterize sets of genes according to their longitudinal patterns of expression. Due to the large number of genes evaluated in GETS analysis, an useful strategy to summarize biological functional ...

Image metadata estimation using independent component analysis and regression [PDF]

open access: yes, 2006
In this paper, we describe an approach to camera metadata estimation using regression based on Independent Component Analysis (ICA). Semantic scene classification of images using camera metadata related to capture conditions has had some success in the ...

Application of independent component analysis to Fermilab Booster

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2005
Autocorrelation is applied to analyze sets of finite-sampling data such as the turn-by-turn beam position monitor (BPM) data in an accelerator. This method of data analysis, called the independent component analysis (ICA), is shown to be a powerful beam ...

B-spline mutual information independent component analysis [PDF]

open access: yes, 2010
Mutual Information is one of the most natural criteria when developing independent component analysis (ICA). Although utilized to some level it has always been difficult to calculate.
