The invention discloses a method, an arrangement, and a system for ascertaining process variables. The method is characterized by multiple steps. The intensities ascertained by a plurality of detectors from different spectral regions of a measurement operation are combined into one intensity vector ({overscore (I)}). A norm of the intensity vector ({overscore (I)}) is calculated therefrom. Those intensity vectors whose norm is less than a definable threshold value (SW) are then discarded. The intensity vectors ({overscore (I)}) are normalized. Processing of the intensity vectors ({overscore (I)}) is accomplished in a vector quantizer (58). Lastly, code book vectors are read out of the vector quantizer (58).
