MaxViT is a family of hybrid (CNN + ViT) image classification models, that achieves better performances across the board for both parameter and FLOPs efficiency than both SoTA ConvNets and Transformers. They can also scale well on large dataset sizes like ImageNet-21K. Notably, due to the linear-complexity of the grid attention used, MaxViT is able to ''see'' globally throughout the entire network, even in earlier, high-resolution stages.

MaxViT meta-architecture:

Results on ImageNet-1k train and test:

Results on ImageNet-21k and JFT pre-trained models:

We have released a Google Colab Demo on the tutorials of how to run MaxViT on images. Try it here

We have provided a list of results and checkpoints as follows:

Here are a list of ImageNet-21K pretrained and ImageNet-1K finetuned models:
