一、问题：在gitbash中执行gitclonexxx之后，并没有弹出登陆框，而是报以下错误git报错fatal:unabletoaccess‘XXX’:SSLcertificateproblem:certificatehasexpired二、解决方法:打开gitbash，输入gitconfig–globalhttp.sslVerifyfalse不出意外可能会继续报错fatal:notinagitdirectory，如没有报错，请忽略。这个问题解决办法是：1.先打开GitBash所在的文件夹2.找到git-cmd.exe3,依次输入以下代码，不要换顺序4.先输gitconfig–globalu

GeneralizingLinearClassification假设我们有如上图的trainingdata，注意到此时\(\mathcal{X}\subset\mathbb{R}^{2}\)。那么decisionboundary\(g\)：\[g(\vec{x})=w_{1}x_{1}^{2}+w_{2}x_{2}^{2}+w_{0}\]即，decisionboundary为某种椭圆，例如：半径为\(r\)的圆（\(w_{1}=1,w_{2}=1,w_{0}=-r^{2}\)），如上图中的黑圈所示。我们会发现，此时decisionboundarynotlinearin\(\vec{x}\)。但
