WebThis means that the dataset will be divided into (8000/32) = 250 batches, having 32 samples/rows in each batch. The model weights will be updated after each batch. one epoch will train 250 batches or 250 updations to the model. here steps_per_epoch = no.of batches. With 50 epochs, the model will pass through the whole dataset 50 times. WebMar 30, 2024 · However in general curve keeps improving. Red curve indicates the moving average accuracy. Moreover, if Early Stopping callback is set-up it will most probably halt the process even before epoch 100, because too many epochs before the improvement happens really! And it happens after 200th epoch.
