It's necessary for us to make a systematic analysis of the characteristics and teaching model of the competitive mathematics.

因此，我们有必要系统地分析竞赛数学的特征及其教学模式。

Neural network need not establish accurate mathematics model, it sums up the relation implicit in the systematic input output through studying input output training sample data.

神经网络不需要建立精确的数学模型，只是通过学习输入输出训练样本数据，就可归纳出隐含在系统输入输出中的关系；
