While I understand that if I train a model using the same data that I test on, then I'll certainly be overfitting, but will the accuracy of that model always be 100%?In other words, is one method of testing whether I've created my model correctly, to test the model by training it on the testing data?
If I train a model using only my testing data, will the accuracy be 100%?
