WebJun 19, 2024 · Dealing With Multi-class Classification Problems. The confusion matrix can be well defined for any N-class classification problem. However, if we have more than 2 classes (N>2), then the above equations (in the confusion matrix figure) do not hold any more. In this article, I show how to estimate all these measures for any number of … WebThe task of growing a classification tree is quite similar to the task of growing a regression tree. Just as in the regression setting, you use recursive binary splitting to grow a classification tree. However, in the classification setting, Residual Sum of Squares cannot be used as a criterion for making the binary splits. Instead, you can use ...
