Decision support system may use data mining techniques for solving problem. Astronomy is an area where Data Mining has been playing a major role. As the astronomical data is very huge, the classification of celestial bodies is the main issue of concern. To improve the classification accuracy a new improved weighted random Forest algorithm is suggested. A decision support system is designed using Weighted Random forest algorithm. The algorithm is implemented in Java. It is observed that weighted random forest performs better than random forest and other tree based data mining classification techniques. 收起
