DaViT
Category: ViT · Code: timm/models/davit.py · Architectures: 8 · Pretrained weights: 5 (3 with ImageNet-1k results)
Dual Attention Vision Transformers (DaViT) combine spatial window attention and channel group attention, both linear in the number of tokens, in a hierarchical design.

- Florence-2: Advancing a Unified Representation for a Variety of Vision Tasks
Usage
See the Quickstart for loading pretrained weights, image preprocessing and fine-tuning, and Feature Extraction for using the models as backbones.
>>> import timm
>>> model = timm.create_model('davit_tiny.msft_in1k', pretrained=True)
>>> data_config = timm.data.resolve_model_data_config(model)Model API support
✓ supported, ✓ (square) works for square sizes only, ✗ not supported, – not needed (the model already accepts any input
size). Checked by running each feature on a randomly initialized model (DaVit with davit_tiny at 224), other
architectures of the same class are expected to behave the same. See the Model API page for details.

davit_small | 49.75 | 8.80 | 224 | 1 |
davit_tiny | 28.36 | 4.54 | 224 | 1 |
GMACs and parameter counts are for the default input size and classifier of each architecture, from the benchmark results.
Pretrained weights
Top-1 is ImageNet-1k validation accuracy from results-imagenet.csv at
the listed eval size, - if the weight has no ImageNet-1k result (e.g. pretraining or image-text weights). Classes is the
size of the pretrained classifier, none for weights without one.
Weights are grouped by source: the paper or origin given in the pretrained config, else a Hub organization other than timm, else the first part of the pretrained tag (architecture.tag). Sources with a single weight are listed under
other.
