2.5 Evaluation of the Model
In each epoch, the loss value of the model on the training set and the test set were obtained simultaneously. Overfitting was determined when the training loss value decreased and the validation loss value increased. We then tested the performance of the model in the test set. Each lesion of vocal cord leukoplakia was considered as a unit for the evaluation of the performance. The subsequent DL workflow used by MaskR-CNN is demonstrated in Figure 2.
