## Model description |
|
|
|
This model is a fine-tuned version of [google/vit-base-patch16-224](https://huggingface.co./google/vit-base-patch16-224), which is a Vision Transformer (ViT) |
|
|
|
ViT model is originaly a transformer encoder model pre-trained and fine-tuned on ImageNet 2012. |
|
It was introduced in the paper "An Image is Worth 16x16 Words: Transformers for Image Recognition at Scale" by Dosovitskiy et al. |
|
The model processes images as sequences of 16x16 patches, adding a [CLS] token for classification tasks, and uses absolute position embeddings. Pre-training enables the model to learn rich image representations, which can be leveraged for downstream tasks by adding a linear classifier on top of the [CLS] token. The weights were converted from the timm repository by Ross Wightman. |
|
|
|
## Intended uses & limitations |
|
|
|
This must be used for classification of x-ray images of the brain to diagnose of brain tumor. |
|
|
|
## Training and evaluation data |
|
|
|
The model was fine-tuned in the dataset [Mahadih534/brain-tumor-dataset](https://huggingface.co./datasets/Mahadih534/brain-tumor-dataset) that contains 253 brain images. This dataset was originally created by Yousef Ghanem. |
|
|
|
The original dataset was splitted into training and evaluation subsets, 80% for training and 20% for evaluation. |
|
For robust framework evaluation, the evaluation subset is further split into two equal parts for validation and testing. |
|
This results in three distinct datasets: training, validation, and testing |
|
