We are using Orange and have 2 files (training and testing). We apply different Learners (kNN, AdaBoost...) and get the Evaluation Results. But we have some doubts about some options in the Test & Score window.
When we apply the option "Test on train data" does it generate for each Learner a model and then applies it to the training population?
And the same about the "Test on test data", does it generate the model with the training data and this option applies it to the testing population?
Because when we get the confusion matrices and we calculate accuracy, sensitivity and specificity the values differ from the ones in the Evaluation Results.
