CIFAR-100 Dataset is an image classification dataset used in the field of machine vision. It has 20 major categories and a total of 100 minor categories. Each minor category contains 600 images (500 training images and 100 test images) and each image has a small label and a large label. The dataset was released in 2009 by Alex Krizhevsky, Vinod Nair, and Geoffrey Hinton from the Department of Computer Science at the University of Toronto.
