Markov Chain is suitable for short-term forecast of great capacity sample data sequence, but gray system forecast method is suitable for medium-term forecast of few capacity sample data sequence.
马尔柯夫链适用于大样本数据序列的短期预测，而灰色系统预测方法适用于小样本数据的中期预测。
The method of dynamic adjusting data to improve the forecast precision in the small sample field is introduced.
文章介绍了在小样本空间中，采用动态调整样本空间数据的手段来提高预测精度；
The results show that using the GM (1, 1) model to forecast the tax data involves a smaller sample and less information. It's easier to build the model and the prediction precision is better.
结果表明，用GM(1,1)模型对税收数据进行预测，不仅所需样本小、信息少，而且建模简单，具有很好的预测精度。
Taking the model test data as sample, the network architecture is determined by two methods, i. e. AGA-BP system and empirical formulae, to forecast the culvert stress.
以模型试验数据为样本，网络结构是由两种方法，即AGA-BP系统和经验公式，预测涵洞的应力。
The meaning of symbolic regression is that we are searching for a function that closely matches an unknown expression based on a finite set of sample data, in order to analyze and forecast data.
符号回归的含义是找出一个符号形式的数学公式，以指定的精度拟合相关变量的有限样本，以便于分析和预测。
Because the nonlinear evolution of slope could be obtained by learning the sample repeatedly with neural network, the forecast effect of neural network is better than those of traditional methods.
由于神经网络可以通过对样本的反复学习来反映边坡复杂的非线性演化关系，其预测效果要优于传统的预测方法。
