说明：  实现了一个用于多币种之间汇率转换的程序。用户可在左侧的下拉框中选择需要转换的两种币种，在上方输入框内输入需要转换的金额，点击“汇率转换”按钮后，下方输出框中显示转换出的对应金额并保留两位小数；点击“清空”按钮后两个文本框内容清空。且输出框内容不可修改。(A program for exchange rate conversion between multiple currencies is implemented. Users can select two currencies to be converted in the drop-down box on the left, enter the amount to be converted in the input box above, click the "exchange rate conversion" button, and display the corresponding amount in the output box below with two decimal digits retained; after clicking the "empty" button, the contents of the two text boxes are empty. And the contents of the output box can not be modified.)

说明：  16QAM、QPSK的MATLAB调制解调源代码(16QAM, QPSK MATLAB modulation demodulation source code)

《Python数据挖掘入门与实践》 本书为数据挖掘入门读物，介绍了数据挖掘的基础知识、基本工具和实践方法，通过循序渐进地讲解算法，带你轻松踏上数据挖掘之旅。本书采用理论与实践相结合的方式，呈现了如何使用决策树和随机森林算法预测美国职业篮球联赛比赛结果，如何使用亲和性分析方法推荐电影，如何使用朴素贝叶斯算法进行社会媒体挖掘，等等。本书也涉及神经网络、深度学习、大数据处理等内容。(Introduction and Practice of Python Data Mining)

盒计数法，差分盒计数法，毯子法，来实现分形维数的计算(Box counting method, differential box counting method and blanket method are used to calculate fractal dimension.)

说明：  蝙蝠算法合集，包括几个测试函数，适合新手学习(The bat algorithm collection, including several test functions, suitable for beginners to learn)

使用SVM分类器来预测乳腺癌病人的预后(特征选择；分类器构建)，评价模型时使用无被交叉验证，性能评价指标包括准确率，AUC，灵敏度，特异度。学会最基本的机器学习方法。可查看分发给大家的代码，以后遇到类似的问题，可用相似的思路和代码。(The SVM classifier was used to predict the prognosis of breast cancer patients (feature selection; classifier construction), and the model was used without cross-validation. Performance evaluation indicators included accuracy, AUC, sensitivity, and specificity. Learn the most basic machine learning methods. You can view the code distributed to everyone, and later encounter similar problems, similar ideas and code can be used.)

主要包括盲信号的检测程序，还包含实验报告和结果(It is mainly used to denoise seismic signals and data, construct seismic data and then denoise the contrast results.)
