# vit-xray-pneumonia-classification |
|
|
|
This model is a fine-tuned version of [google/vit-base-patch16-224-in21k](https://huggingface.co/google/vit-base-patch16-224-in21k) on the chest-xray-classification dataset. |
|
It achieves the following results on the evaluation set: |
|
- Loss: 0.0868 |
|
- Accuracy: 0.9742 |
|
|
|
