sequential access is a method of data access where information in a storage device is accessed in a sequence or order. it's like listening to songs on a cassette tape; you must go through each song to reach the one you want. this is different from random access where any data can be ...
Fits the model on data yielded batch-by-batch by a Python generator. The generator is run in parallel to the model, for efficiency. For instance, this allows you to do real-time data augmentation on images on CPU in parallel to training your model on GPU. The use of keras.utils.Sequenc...
