ICA                     Independent Component Analysis The input data
                        is assumed to be a matrix. ICA decomposes the
                        matrix and extract the components that are
                        statistically independent each other.
MICA                    Multimodal independent component analysis The
                        input datasets are assumed to be two matrices
                        sharing the column space. MICA decomposes the
                        matrices simutanously and extracts the
                        components that maximizes the mutual
                        information between the components.
MultilinearICA          Multilinear independent component analysis The
                        input object is assumed to be a Tensor object
                        defined by rTensor package. In MultilinearICA,
                        ICA function is performed in each mode of the
                        tensor.
