SpletThe anatomy of a learning curve. Learning curves are plots used to show a model's performance as the training set size increases. Another way it can be used is to show the model's performance over a defined period of time. We typically used them to diagnose algorithms that learn incrementally from data. Splet16. okt. 2013 · I have my SVM implemented. But when I want to obtain a ROC curve for 10-fold cross validation or make a 80% train and 20% train experiment I can't find the answer to have multiple points to plot. I understand that sensitivity vs 1-specificity is plotted, but after svm obtain predicted values, you have only one sensitivity and one specificity.
