It was introduced in the paper [Dilated Neighborhood Attention Transformer](https://arxiv.org/abs/2209.15001) by Hassani et al. and first released in [this repository](https://github.com/SHI-Labs/Neighborhood-Attention-Transformer). ## Model description DiNAT is a hierarchical vision transformer based on Neighborhood Attention (NA) and its dilated variant (DiNA). Neighborhood Attention is a restricted self attention pattern in which each token's receptive field is limited to its nearest neighboring pixels. NA and DiNA are therefore sliding-window attention patterns, and as a result are highly flexible and maintain translational equivariance. They come with PyTorch implementations through the [NATTEN](https://github.com/SHI-Labs/NATTEN/) package. ![model image](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/dilated-neighborhood-attention-pattern.jpg) [Source](https://paperswithcode.com/paper/dilated-neighborhood-attention-transformer) ## Intended uses & limitations You can use the raw model for image classification. See the [model hub](https://huggingface.co/models?search=dinat) to look for fine-tuned versions on a task that interests you. ### Example Here is how to use this model to classify an image from the COCO 2017 dataset into one of the 1,000 ImageNet classes: ```python from transformers import AutoImageProcessor, DinatForImageClassification from PIL import Image import requests url = "http://images.cocodataset.org/val2017/000000039769.jpg" image = Image.open(requests.get(url, stream=True).raw) feature_extractor = AutoImageProcessor.from_pretrained("shi-labs/dinat-tiny-in1k-224") model = DinatForImageClassification.from_pretrained("shi-labs/dinat-tiny-in1k-224") inputs = feature_extractor(images=image, return_tensors="pt") outputs = model(**inputs) logits = outputs.logits # model predicts one of the 1000 ImageNet classes predicted_class_idx = logits.argmax(-1).item() print("Predicted class:", model.config.id2label[predicted_class_idx]) ``` For more examples, please refer to the [documentation](https://huggingface.co/transformers/model_doc/dinat.html#). ### Requirements Other than transformers, this model requires the [NATTEN](https://shi-labs.com/natten) package. If you're on Linux, you can refer to [shi-labs.com/natten](https://shi-labs.com/natten) for instructions on installing with pre-compiled binaries (just select your torch build to get the correct wheel URL). You can alternatively use `pip install natten` to compile on your device, which may take up to a few minutes. Mac users only have the latter option (no pre-compiled binaries). Refer to [NATTEN's GitHub](https://github.com/SHI-Labs/NATTEN/) for more information. ### BibTeX entry and citation info ```bibtex @article{hassani2022dilated, title = {Dilated Neighborhood Attention Transformer}, author = {Ali Hassani and Humphrey Shi}, year = 2022, url = {https://arxiv.org/abs/2209.15001}, eprint = {2209.15001}, archiveprefix = {arXiv}, primaryclass = {cs.CV} } ```
