smote过采样方法对不平衡数据集进行人工数据合成(smote oversampling and classification)

提出基于高速公路收费站进出口数据推算OD矩阵的一般方法。在缺乏初始OD矩阵的条件下,结合指数平滑法和无约束重力模型思想,通过VB编程反复迭代进行初始OD矩阵推算 利用组合模型预测高速公路各收费站出入口流量,通过弗雷特法进行OD分布推算。以沪宁高速公路为例证实此方法具有较高的精度。(Proposed highway toll station-based import and export data projections general OD matrix method. Lack of initial OD matrix conditions, combined with the exponential smoothing and unconstrained gravity model of thinking, through the VB Programming iterative initial OD Matrix Estimation flow of the use of a combination of model predictions highway toll station entrances and exits through Fratar Method for OD distribution projections. Shanghai-Nanjing Expressway, for example to confirm that this method has higher accuracy.)

主要用来计算抛物型偏微分方程的数值解，而且通过调用边界函数来计算方程，采用差分编程方式(Mainly used to calculate the parabolic partial differential equations numerical solution, and by calling the function to calculate the equation of the border, using differential programmatically)

F-K域偏移法和相移法偏移程序（C语言）(FK domain migration method and the phase- shift method migration program (C language))

是用MATLABA编写的遗传运算发的一个小程序 挺好用的 大家(MATLABA is prepared by the genetic operator issued a small procedure very well, we try to use)

该程序实现的是计算器功能，包含简单的加减乘除，以及取余、求倒等功能计算。(The program is a calculator function, contain simple addition and subtraction, multiplication and division, and modulo, seeking poured functions calculation.)
