How is Validation and Test cost calculated in Classification Learner app?
显示 更早的评论
I used SVM for classification with LBP features as input. I used 20 percent data for testing in classification learner app with 10-fold Corss-validation. In the summary tab of output it calculates Total Validation and Total Test cost. How does it calculate these numbers?

Hi Satish
The validation and testing cost refer to the total number of misclassifications. By default, the app assigns a penalty of 0 if the observation is classified correctly and a penalty of 1 if the observation is classified incorrectly. The penalties can also be changed according to model requirements. You can read more about it in the documentation below.
Hope this helps!

Yes, the cost is inversely proportional to the accuracy.
