Abstract Background We propose rigorously optimised supervised feature extraction methods for multilinear data based on Multilinear Discriminant Analysis (MDA) and demonstrate their usage on Electroencephalography (EEG) and simulated data. While existing MDA methods use heuristic optimisation procedures based on an ambiguous Tucker structure. we propose a rigorous approach via optimis... https://parisnaturalfoodes.shop/product-category/org-baobab-fruit-powder/
