... Classification models A classification model (CM) consists of the following components: Class definitions are given by means of a learning sample, implicitly including the number N and names of the defined classes. ... Optimal loss factors In case of classification aim (3) a set of three optimal loss factors -- weights for di#erent kinds of misclassifications -- has to be stated (Christlieb et al. 1998). ... The classification of spectra of unknown classes can then be carried out under MIDAS. ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...

... Introduction: E-, M- and S-type asteroids are widely considered as remnants of differentiated parent bodies; specifically, Ms might have been their cores [e. g., 1, 2]. The conviction is based on the visible-range albedo (medium to high) and overall spectral curves (slightly reddish to red) of the small planets corresponding to these of metal iron and igneous silicate assemblages. ... It seems the spectral features superimpose to the spectral characteristics of metal iron and igneous silicates. ...
