Generalised Canonical Correlation Analysis for the interpretation of fluorescence spectral data

The paper reports an application of Generalised Canonical Correlation Analy sis to fluorescence spectral data. Emission fluorescence spectra can be rec orded for several excitation wavelengths and can be presented as 3-way data tables. The objectives of the data treatment are to describe and compare t he samples by taking into account all the emission spectra, and to reveal c haracteristic excitation and emission wavelengths. Generalised Canonical Co rrelation Analysis has been tested on fluorescence emission spectra acquire d for binary mixtures of raw materials in the food domain. The application of the method within the context oi spectral data is presented.
