决策向量

Take a casting company as an example to research the optimization of master production scheduling.

在生产计划决策时，运用统计学建立产品市场需求预测模型，利用支持向量机回归预测的优点进行预测。

The weight vector of triangular fuzzy complementary judgement matrix is obtained by solving the model.

通过求解该模型得到三角模糊数互补判断矩阵的权重向量，并利用已有的三角模糊数排序公式求得决策方案的排序。

This model uses nonlinear mapping to map samples into high dimensional feature space, and compares the distribution of each type of samples in the high dimensional space. So that a binary decision tree is constructed through clustering, which can make the more separable classes classified at the upper node of the binary decision tree. The model overcomes the accumulation of misclassification and avoids the condition of impartibility efficiently. At the same time, each node of decision tree uses binary least squares wavelet support vector machine to obtain higher generalization ability.

该模型利用非线性映射将样本投影到高维特征空间，比较每类样本在高维空间的分布情况，进行聚类构造出一个二叉决策树，使容易区分的类别从根节点逐层分类出来，有效克服了错分积累和避免不可分情况；同时，各个节点采用二值最小二乘小波支持向量机，以获得较高的泛化能力。

After analysis and study on email, by disperseing and charactering email, my paper use vector to express email. And then bring forward a determination tree classifying model base on information entropy. At last I do a series of experiment and testing.

本文通过对电子邮件的分析和研究，提出对邮件结构字段信息和邮件正文信息加以离散和特征化处理，用向量的方式表示电子邮件；接着针对向量化的邮件表示，建立了一种基于信息熵的决策树邮件分类识别模型；论文最后通过编程对该模型作了一系列的实验和测试。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
