This a Bayesian Ica algorithm for the linear instantaneous mixing model with additive Gaussian noise

This a Bayesian Ica algorithm for the linear instantaneous mixing model with additive Gaussian noise [1]. The inference problem is solved by ML-II, i.e. the sources are found by integration over the source posterior and the noise covariance and mixing matrix are found by maximization of the marginal likelihood [1]. The sufficient statistics are estimated by either variational mean field theory with the linear response correction or by adaptive TAP mean field theory [2,3]. The mean field equations are solved by a belief propagation method [4] or sequential iteration. The computational complexity is N M^3, where N is the number of time samples and M the number of sources.

The Ica/BSS algorithms are pure mathematIcal formulas, powerful, but rather mechanIcal procedures: There is not very much left for the user to do after the machinery has been optimally implemented. The successful and efficient use of the IcaLAB strongly depends on a priori knowledge, common sense and appropriate use of the preprocessing and postprocessing tools. In other words, it is preprocessing of data and postprocessing of models where expertise is truly ne

Ica can be used in brain activation studies to reduce the number of dimension and filter out independent and interesting activations. This demonstration shows two studies. One provided by Hvidovre Universitets Hospital, Denmark, that consists of fMRI scannings of humans. Another provided by the EU sponsored MAPAWAMO project from fMRI scannings of monkeys. In the demo comparison between IcaMS, IcaML, IcaMF, IcaMF (positive sources) and PCA can be made. More detailes can found in [2].

Ica is used to classify text in extension to the latent semantic indexing framework. Ica show to align the context grouping structure well in a human sense [1], thus can be used for unsupervised classifIcation. The demonstration shows this on medIcal abstracts (MED dataset), that uses BIC to estimate the number of classes and produces keywords for each class. The IcaML algorithm is used.
