The CIFAR-10 data consists of 50,000 32x32 color images in 10 classes. There are 40,000 training images and 10,000 test images in the data. We have preserved the train/test split from the original dataset.
The label classes in the dataset are:
airplane
automobile
bird
cat
deer
dog
frog
horse
ship
truck
The classes are completely mutually exclusive. There is no overlap between automobiles and trucks. "Automobile" includes sedans, SUVs, things of that sort. "Truck" includes only big trucks. Neither includes pickup trucks.
