Abstract

The huge number of descriptive features is often a problem in data mining. We analyzed structure activity data for dopamine antagonists, which involves selecting useful features from numerous fragments extracted from their chemical structures. Correlation coefficients among categorical variables were used to select attributes. Chemists evaluated the rules obtained by the cascade model, and the importance of attribute selection was confirmed.
