Description

Vina conducted a comparison test of her rule-based system, BEAGLE, the nearest-neighbor algorithm, and discriminant analysis. BEAGLE is a product available through VRS Consulting, Inc.; 4676 Admiralty Way, Suite 206; Marina Del Ray, CA 90292 (213) 827-7890 and FAX: -3189. The study of the classification of types of glass was motivated by criminological investigation. At the scene of th, the glass left can be used as evidence...if it is correctly identified!
