| Abstract: | Based on discussing the basic concept of data mining technique and decision tree method,combining with hailstorm disasters data in some areas of Mudanjiang region,using decision tree C4.5 algorithm,agricultural meteorological disaster grade decision tree forecasting model was established. Through the prediction model,direct economic loss was forecasted,which will provide rational mining model in the field. |
