""" The EfficientNet Family in PyTorch
|
|
|
|
An implementation of EfficienNet that covers variety of related models with efficient architectures:
|
|
|
|
* EfficientNet-V2
|
|
- `EfficientNetV2: Smaller Models and Faster Training` - https://arxiv.org/abs/2104.00298
|
|
|
|
* EfficientNet (B0-B8, L2 + Tensorflow pretrained AutoAug/RandAug/AdvProp/NoisyStudent weight ports)
|
|

|
|
- CondConv: Conditionally Parameterized Convolutions for Efficient Inference - https://arxiv.org/abs/1904.04971
|
|
- Adversarial Examples Improve Image Recognition - https://arxiv.org/abs/1911.09665
|
|
- Self-training with Noisy Student improves ImageNet classification - https://arxiv.org/abs/1911.04252
|
|
|
|
* MixNet (Small, Medium, and Large)
|
|
- MixConv: Mixed Depthwise Convolutional Kernels - https://arxiv.org/abs/1907.09595
|
|
|
|
* MNasNet B1, A1 (SE), Small
|
|

|
|
|
|
* Single-Path NAS Pixel1
|
|
- Single-Path NAS: Designing Hardware-Efficient ConvNets - https://arxiv.org/abs/1904.02877
|
|
|
|
* TinyNet
|
|
- Model Rubik's Cube: Twisting Resolution, Depth and Width for TinyNets - https://arxiv.org/abs/2010.14819
|
|
- Definitions & weights borrowed from https://github.com/huawei-noah/CV-Backbones/tree/master/tinynet_pytorch
|
|
|
|
* And likely more...
|
|
|
|
The majority of the above models (EfficientNet*, MixNet, MnasNet) and original weights were made available
|
|
by Mingxing Tan, Quoc Le, and other members of their Google Brain team. Thanks for consistently releasing
|
|
the models and weights open source!
