能够对一天之中每隔15min的电力负荷数据进行预测(load forecast based on BP neural network)

说明：  用到的数据是2015微博用户画像比赛提供的数据，数据包含在文件中。这份代码能够实现完整的提取特征到训练模型，从而的出预测结果的功能。用到了sklearn及panda包。(The data used is provided by the user portrait competition of microblog in 2015. This code can complete the function of extracting features to the training model, thus producing the prediction results. Sklearn and panda packages are used.)

学生选课、查看成绩，老师修改提交学生成绩。(student manage system)

说明：  matlab语言实现单目标优化，采用遗传算法(Single objective optimization)

：提出安全协议本质上是协议主体利用密码学手段通过挑战一响应来对协议另一方的存在做出判断，并同 时完成对一些数据例如会话密钥等的协商。依据这种思想，结合认证逻辑中的一些成果，提出了一种新的安全协 议关联性的分析方法，该方法对协议认证目标进行了基于线空间模型语义的定义，并将关联性分析归结为Strand 的存在关系和Strand参数一致性的分析问题。-: proposed security agreement on the nature of the agreement is the main means of the use of cryptography through the response to a challenge to the existence of other agreements made judgment and be completed at the same time on some key data such as the oral consultations. Based on this idea and certification of some logical outcome, a new security agreement relevance of the analysis method, The objective of the agreement for the certification based on linear space model semantic definition, Correlation analysis will be reduced to the existence of relations between the Strand and Strand parameters consistency of the problem.

说明：  实现粒子滤波的函数，它可以用于参数估计时候调用.(It can be used in parameter estimation.)
