第一次作业_基于分类算法的雷达状态识别
说明: 第一次作业_基于分类算法的雷达状态识别
对于本数据集中的雷达状态识别,数据降维前使用朴素贝叶斯、支持向量机、神经网络的分类算法对于识别的准确率无太大影响;数据降维后使用神经网络算法最优,支持向量机算法其次,朴素贝叶斯算法较差。此外,训练样本越多,分类准确率有小幅度提高。(First Operation Radar State Recognition Based on Classification Algorithms For radar state recognition in this data set, the classification algorithm of Naive Bayesian, Support Vector Machine and Neural Network before data dimension reduction has little effect on the accuracy of recognition; Neural Network algorithm is the best after data dimension reduction, Support Vector Machine algorithm is the second, Naive Bayesian algorithm is the worst. In addition, the more training samples, the smaller the classification accuracy.)

COM_customplot
说明: 自己用的小软件,仿造原子的XCOM功能,加了一下自己用的功能。
1、基本串口通讯,鼠标放入串口选择自动刷新,显示COM口的驱动类型。
2、多条发送界面,可定时发送,可关联数字键盘、右键发送按钮可更改按钮名称,方便记忆。
3、485通讯,数据有十进制和十六进制可选,发送后自动保留记录。
4、CRC校验小工具。
5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制
6、字符格式示波器,例:">P:-1.25",示波器显示曲线名称P,数值-1.25,曲线个数最多8个。
7、类似MODBUS协议截取第2-5位,合成一个int数值,然后示波器显示波形,最多5个曲线
8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)
