基于socket及tkinter实现聊天室

说明：  包含实验报告和代码，高级计算机网络的第一次试验(Include lab report and code)

提升方法是将弱学习算法提升为强学习算法的统计学习方法。在分类学习中，提升方法通过反复修改训练数据的权值分布，构建一系列的基本分类器（弱分类器），并将这些基本分类器线性组合，构成强分类器。提升树是建立在决策树上的一种提升方法。针对回归、分类问题，它采用的损失函数不同。对于回归问题，通常使用平方误差损失函数；而对于分类问题，通常使用指数损失函数。代表性的方法主要有AdaBoost算法以及梯度提升树算法（GBDT)。

【实例简介】 这算是一个网络编程，服务端开启服务器后，客户端需输入服务端的主机IP才能开始聊天 注意：服务端不能加入聊天，该为使用GUI界面聊天，所以需要socket及tkinter库

Python机器学习——预测分析核心算法(MICHAEL BOWLES teaches machine learning at Hacker Dojo in Silicon Valley, consults on machine learning projects, and is involved in a number of startups in such areas as bioinformatics and high-frequency trading. Following an assistant professorship at MIT, Michael went on to found and run two Silicon Valley startups, both of which went public. His courses at Hacker Dojo are nearly always sold out and receive great feedback from participants.)

通过各种不同的算法实现室内高精度定位，比如说KNN，随机森林，SVM，等等。(Indoor high-precision positioning is achieved by various algorithms, such as KNN, random forest, SVM, and so on.)

图片转字符画，可以保存为txt等格式（Python语言）(convert picture to character painting by python)

用Python实现了网页数据的抓取，网页动态图的浮现，字体颜色大小的改变，网页数据爬取，制作相关网页，用表格体现，并改变了表格的风格，(Python is used to capture web page data, the emergence of dynamic graph, the change of font size, the crawl of web page data, the production of relevant web pages, which are represented by tables, and the style of tables is changed.)
