[NEW!] Check out our latest work involution accepted to CVPR'21 that introduces a new neural operator, other than convolution and self-attention.

PyTorch implementation of EfficientNet V2

Reproduction of EfficientNet V2 architecture as described in EfficientNetV2: Smaller Models and Faster Training by Mingxing Tan, Quoc V. Le with the PyTorch framework.

Models

| Architecture | # Parameters | FLOPs | Top-1 Acc. (%) | | ----------------- | ------------ | ------ | -------------------------- | | EfficientNetV2-S | 22.10M | 8.42G @ 384 | | | EfficientNetV2-M | 55.30M | 24.74G @ 480 | | | EfficientNetV2-L | 119.36M | 56.13G @ 480 | | | EfficientNetV2-XL | 208.96M | 93.41G @ 512 | |

Stay tuned for ImageNet pre-trained weights.
