Classification and analysis of emission-line galaxies using mean field independent component analysis [PDF]

open access: yes, 2013
We present an analysis of the optical spectra of narrow emission-line galaxies, based on mean field independent component analysis (MFICA). Samples of galaxies were drawn from the Sloan Digital Sky Survey (SDSS) and used to generate compact sets of ...

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 ...

A Constrained EM Algorithm for Independent Component Analysis [PDF]

open access: yes, 2001
We introduce a novel way of performing independent component analysis using a constrained version of the expectation-maximization (EM) algorithm. The source distributions are modeled as D one-dimensional mixtures of gaussians.

Independent component approach to the analysis of EEG and MEG recordings [PDF]

open access: yes, 2000
Multichannel recordings of the electromagnetic fields emerging from neural currents in the brain generate large amounts of data. Suitable feature extraction methods are, therefore, useful to facilitate the representation and interpretation of the data ...

Meta-Analysis of Esophageal Cancer Transcriptomes Using Independent Component Analysis

open access: yesFrontiers in Genetics, 2021
Independent Component Analysis is a matrix factorization method for data dimension reduction. ICA has been widely applied for the analysis of transcriptomic data for blind separation of biological, environmental, and technical factors affecting gene ...

Background Subtraction Approach Based on Independent Component Analysis

open access: yesSensors, 2010
In this work, a new approach to background subtraction based on independent component analysis is presented. This approach assumes that background and foreground information are mixed in a given sequence of images.

aNy-way Independent Component Analysis [PDF]

open access: yes2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2020
AbstractMultimodal data fusion is a topic of great interest. Several fusion methods have been proposed to investigate coherent patterns and corresponding linkages across modalities, such as joint independent component analysis (jICA), multiset canonical correlation analysis (mCCA), mCCA+jICA, disjoint subspace using ICA (DS-ICA) and parallel ICA.

Independent component analysis: algorithms and applications [PDF]

open access: yes, 2000
A fundamental problem in neural network research, as well as in many other disciplines, is finding a suitable representation of multivariate data, i.e. random vectors.

Complex Independent Component Analysis of Frequency-Domain Electroencephalographic Data

open access: yes, 2003
Independent component analysis (ICA) has proven useful for modeling brain and electroencephalographic (EEG) data. Here, we present a new, generalized method to better capture the dynamics of brain signals than previous ICA algorithms.

Assessing material densities by vibration analysis and independent component analysis [PDF]

open access: yes, 2013
The aim of this study was to investigate vibration analysis and independent component analysis (ICA) to assess the density of multiple materials making up a single structure.
