Supervised Classification and Unsupervised Classification
some clustering algorithm to classify an image data [Richards, 1993, p8 5]. These procedures can be used to determine the number and location of the unimodal spectral classes. One of the most commonly used unsupervised classifications is the migrating means clustering classifier (MMC). This method is based on labeling each

Comments from students on teaching evaluation forms
lweb.cfa.harvard.eduComments from students on teaching evaluation forms: • I found Søren to be a wonderful TA. The things that he taught me helped me a great deal in this class as well as in my lecture. Because of his explanations I am doing very well in both my Astronomy classes. Because of the help and attention
