| Abstract: | By using the method of pattern recognition, various features in the preparation of strong earthquakes have been selected and analysed. The relationship between features are tested and the effect of each feature are verified. It is proposed to use a few features to describe the preparation of an earthquake and make classification prediction. The typical features and the typical time intervals are also analysed. It provides basis for bettering the effect of classification. |
