Dataset ART

Three-way artificial dataset constituted by 50 samples that simulate mixtures of two chemicals. Data structure: 50 rows = concentrations 100 columns = spectra 100 tubes = elution profiles The original signal is the product of the three real matrices with two columns (two factors), concentrations, spectra, elution profiles. A Gaussian noise was added to the product, at five levels, with mean absolute error equal to 2, 5, 20, 50 and 100 thousands of the maximum signal, so that ART is actually a family of five datasets, from ART1 to ART5.
