CiteSeerX — Citation Query Independent component analysis ...
New and emerging applications, such as data mining, web searching, retrieval of multimedia data, face recognition, and cursive handwriting recognition, require robust and efficient pattern recognition techniques. ... Independent component analysis (ICA) is a statistical method for transforming an observed multidimensional random vector into ......
ICA for dummies – Arnaud Delorme
Now, if one want to remove component number 2 from the data (for instance if component number 2 proved to be an artifact), one can simply subtract the matrix above (XC2) from the original data X. Note that in the matrix computed above (XC2) all the columns are proportional, which mean that the scalp activity is simply scaled. For this reason, we denote the columns of the W-1 matrix, the scalp ...
Independent Component Analysis - an overview ...
jICA is an extension of the popular independent component analysis (ICA). Briefly, ICA is a technique for revealing hidden factors that underlie a set of observable data. ICA has been widely used to solve blind source separation problems (Fig. 16.3); these include, for example, the problem of deriving brain waves recorded using multiple sensors and the problem of removing interfering radio ...

Independent component analysis: an introduction ...
Independent component analysis (ICA) is a method for automatically identifying the underlying factors in a given data set. This rapidly evolving technique is currently finding applications in analysis of biomedical signals (e.g. ERP, EEG, fMRI, optical imaging), and in models of visual receptive fields and separation of speech signals.
Independent Principal Component Analysis for biologically ...
Independent Principal Component Analysis (IPCA) makes the assumption that biologically meaningful components can be obtained if most noise has been removed in the associated loading vectors. In IPCA, PCA is used as a pre-processing step to reduce the dimension of the data and to generate the loading vectors.
Learning Modewise Independent Components from Tensor Data ...
Independent component analysis (ICA) is a popular unsupervised learning method. This paper extends it to multilinear modewise ICA (MMICA) for tensors and explores two architectures in learning and recognition. MMICA models tensor data as mixtures generated from modewise source matrices that encode statistically independent information....
Independent Component Analysis based on multiple data ...
Independent Component Analysis based on multiple data-weighting. 05/31/2019 ∙ by Andrzej Bedychaj, et al. ∙ 0 ∙ share . Independent Component Analysis (ICA) - one of the basic tools in data analysis - aims to find a coordinate system in which the components of the data are independent....
