list是Python中的普通列表对象,支持append和attend操作,没有shape属性;array和matrix是numpy数据库中的对象,不支持append和attend操作,具有shape属性。 一个list中可以存放不同类型的数据,如int、float、str,或者布尔型;而array和matrix中只能存放相同类型的数据。 list不支持乘法操作;array和matrix支持乘法操作。 list对象...
Confusion Matrix in Python: plot a pretty confusion matrix (like Matlab) in python using seaborn and matplotlib - wcipriano/pretty-print-confusion-matrix
Write your own programs using the Matrix in C++ or one of the bindings such as Python or C#. Wiring / Boards Please see theAdadpter Boards or Self Wiring. Summary is: Yes you can self wire without level shifters and it will work most of the time, but if you're not in a hurry get...

实现的时候需要注意一点,在Python中取list中的值时,如果索引是负值的话会从后面往前数返回对应的元素,而以前我们用其他语言的时候肯定是提示越界了,所以代码中用来存储结果的数数组是(n+1)x(n+1),而不是nxn的,这样的话就能够保证返回的是0,而不是从后往前数得到的结果。 得到的数组m如下,m[1,6]就是我们...

python3 如何评价模型的表现(分类指标:confusion matrix、ROC、AUC),1.错误率和准确率准确率不是评价模型好坏的标准,如遇到类别不平衡(classimbalance)的数据,典型的垃圾邮件问题,99%的邮件都是非垃圾邮件,1%为垃圾邮件,那分类准确率99%就没有什么意义。错误率=
