Keras Models Performance

  • The top-k errors were obtained using Keras Applications with the TensorFlow backend on the 2012 ILSVRC ImageNet validation set and may slightly differ from the original ones.

The input size used was 224x224 for all models except NASNetLarge (331x331), InceptionV3 (299x299), InceptionResNetV2 (299x299), Xception (299x299),
EfficientNet-B0 (224x224), EfficientNet-B1 (240x240), EfficientNet-B2 (260x260), EfficientNet-B3 (300x300), EfficientNet-B4 (380x380), EfficientNet-B5 (456x456), EfficientNet-B6 (528x528), and EfficientNet-B7 (600x600).

notice

  • Top-1: single center crop, top-1 error
  • Top-5: single center crop, top-5 error
  • 10-5: ten crops (1 center + 4 corners and those mirrored ones), top-5 error
  • Size: rounded the number of parameters when include_top=True
  • Stem: rounded the number of parameters when include_top=False
