CIFAR-10和CIFAR-100是8000万微型图像数据集的子集。它们由亚历克斯·克里日夫斯基、维诺德·奈尔和杰弗里·辛顿收集。
CIFAR-10 数据集
CIFAR-10数据集包含10个类,总共有60000张32x32彩色图像,每个类包含6000张图像。培训图片50000张,测试图片10000张。
数据集分为5个训练集和1个测试集,每个集包含10000张图像。测试组恰好包含每个类中随机选择的1000张图像。训练组则随机地包含其余的图像,但是一些训练组可能包含来自一个类的图像多于另一个类的图像。在它们之间,训练组包含每个类的5000个图像。
10个类包括:
airplane 、automobile、bird、cat、deer、dog、frog、horse、ship、truck
CIFAR-100数据集
这个数据集与CIFAR-10类似,只是它有100个类,每个类包含600张图像。每班有500张训练图片和100张测试图片。CIFAR-100中的100个类被分为20个超类。每个图像都带有一个“精细”标签(它所属的类)和一个“粗”标签(它所属的超类)。
