摘要：

Pattern Recognition is one of main methods that can resolve structure of chemistry and classification of compounds. In chemistry, K-Nearest Neighbor method (KNN) is mostly used for recognition of compounds that are not classified by a linear method. ALKNN (Alternative KNN) is an improvement of KNN. The method is based on the classification rules which are produced by using standards and knowledge. The unknown samples are,then, classified with the aid of the rules.
