A straightforward and intuitive method for evaluating a classification model is to measure the total or average misclassification cost that is associated with the prediction errors that are made by a classification model. The average misclassification cost is independent of the number of observations in the test set.

WebWhen the initial learning rate was set to 0.1, after 60 epochs of training, the model accuracy was only 16.06%, and the corresponding loss was 0.259, both of which show significant variations.
