决策树算法实现

解析读取excel工具，主要用于跟excel文件相关的处理，能根据需求读取excel相关key的值，eg：#useAge:#import excelReader#reader = excelReader.getReader();#reader.Read(excelPath);#excelInfo = reader.GetExcelInfoByPathAndSheetName(excelPath,"Main");#excelRows = excelInfo.GetExcelRows();#for row in excelRows:#     rowCells = row.GetRowCells();#     for cell in rowCells:#         print("key = %s,v = %s,type=%s"%(cell.GetKey(),cell.GetValue(),cell.GetType()));

说明：  朴素贝叶斯是经典的机器学习算法之一，也是为数不多的基于概率论的分类算法。朴素贝叶斯原理简单，也很容易实现，多用于文本分类，比如垃圾邮件过滤。(Naive Bayes is one of the classical machine learning algorithms, and is also one of the few classification algorithms based on probability theory. Naive Bayesian principle is simple and easy to implement. It is mostly used for text categorization, such as spam filtering.)

用决策树来训练数据，并测试准确率。将数据进行拆分，分成训练数据和测试数据，用训练数据所预测的结果，来与测试数据进行比较，相同即为准确，正确的数量比测试数据总量就是准确率。并查看内存利用率。

基于树莓派B+版本的车牌识别设计，辨识部分以树莓派3B+/3B为核心处理器，基于Linux平台，通过python3.5和OpenCV来对含有车牌信息的图片，进行高斯去噪、灰度化、边缘检测、二值化、闭操作、字符分割、字符识别匹配等一系列图像处理操作最终实现车牌识别这个系统。(Based on the design of license plate recognition of raspberry pie B+version, the recognition part takes raspberry pie 3B+/3B as the core processor, and based on Linux platform, uses Python 3.5 and OpenCV to process the image containing license plate information, and carries out a series of image processing operations such as Gaussian denoising, graying, edge detection, binarization, closed operation, character segmentation, character recognition matching, etc. Finally, the system of license plate recognition is realized)

首先给出了社交网络中热点话题趋势预测的形式化定义和一个话题趋势预测模型，然后提出了一种针对时间序列数据进行特征抽取和构造的新方法，基于提出的新方法构造了三个相互补充的特征子集，最后将这三个特征子集线性组合起来做为支持向量机的输入向量进行话题趋势的预测。为了验证预测模型的性能，本论文釆集了一个高质量的新浪微博数据集。基于获取到的数据，对预测模型进行了完整的测试，取得了良好的效果。
