Why make my own ResNet50 training data set out of the question, is the effect on the training set and validation set are good, 99.99% on the training set, validation set is 99%, but at the time of epoch=50 test set accuracy is 88%, epoch accuracy test set for 93=100, there are two questions first, why the data accuracy test set and validation set differ?? Large, I think should be the same ah, your second question, the epoch, the more the better the results, in the training set and validation set effect is the same, why the effect of the test set was also higher
