Abstract

Heuristic evolving latent projections (HELP) are proposed as a new method to resolve two-way bilinear multicomponent data into spectra and chromatograms of the pure constituents. The method is founded on four elements: (I) the use of the so-called zero-component regions in order to establish the detection limit for the chemical species, (II) the use if latent-projective graphs (datascope) to reveal selective (one-component) chormatographic and/or spectral regions, (III) local rank analysis in order to check the selectivity of the regions found by visual detection, and (IV) the use of the selective information for unique resolution into spectra and chromatograms of the pure chemical constituents
