Abstract: Feature selection is a very important and difficult problem in the pattern recognition of underground nuclear explosions and natural earthquakes. To solve this problem, a new method for feature selection based on ordinal optimization was presented in this paper, and an experiment based on blind picking rule was carried out. Experiment results and corresponding analysis indicate that this method can reduce the search space greatly and enhance the search efnciency. The blind picking rule is applied to the feature selection of underground nuclear explosions and natural earthquakes, and the recognition rate reaches up to 97.5 % . It may be a novel solution for the feature selection of underground nuclear explosion and natural earthquake events.
