# Brain Tumor Detection
|
| 18 |
-
|
| 19 |
-
## Model Description
|
| 20 |
-
|
| 21 |
-
|
| 22 |
-
This model is a ConvNeXt Tiny architecture trained with FastAI for detecting brain tumors in MRI scans.
|
| 23 |
-
It can classify brain MRI images as either showing signs of a tumor or being normal (no tumor detected).
|
| 24 |
-
Note: This model uses FastAI format and requires specific loading procedures.
|
| 25 |
-
|

## Usage
|
| 56 |
-
|
| 57 |
-
```python
|
| 58 |
-
from transformers import AutoModelForImageClassification, AutoImageProcessor
|
| 59 |
-
from PIL import Image
|
| 60 |
-
import torch
|
| 61 |
-
|
| 62 |
-
# Load model and processor
|
| 63 |
-
model = AutoModelForImageClassification.from_pretrained("your-username/brain-tumor-detection")
|
| 64 |
-
processor = AutoImageProcessor.from_pretrained("your-username/brain-tumor-detection")
|
| 65 |
-
|
| 66 |
-
# Load and process image
|
| 67 |
-
image = Image.open("path_to_image.jpg")
|
| 68 |
-
inputs = processor(image, return_tensors="pt")
|
| 69 |
-
|
| 70 |
-
# Make prediction
|
| 71 |
-
with torch.no_grad():
|
| 72 |
-
outputs = model(**inputs)
|
| 73 |
-
predicted_class_id = outputs.logits.argmax().item()
|
| 74 |
-
predicted_class = model.config.id2label[predicted_class_id]
|
| 75 |
-
|
| 76 |
-
print(f"Predicted class: {predicted_class}")
|
| 77 |
-
```
|
| 78 |
-
|
| 79 |
-
## Training Details
|
| 80 |
-
|
| 81 |
-
This model was fine-tuned from pre-trained vision transformers on medical image datasets. For detailed training information, please refer to the original model documentation.
|
| 82 |
-
|
| 83 |
-
## Evaluation
|
| 84 |
-
|
| 85 |
-
The model has been tested on held-out validation sets with the reported accuracy metrics. However, clinical evaluation and validation are required before any medical application.
|
| 86 |
-
|
| 87 |
-
## Ethical Considerations
|
| 88 |
-
|
| 89 |
-
- Medical AI models can have significant impact on human health
|
| 90 |
-
- Proper validation and regulatory approval required for clinical use
|
| 91 |
-
- Potential for bias in training data and model predictions
|
| 92 |
-
- Should be used responsibly with appropriate medical oversight

## FastAI Usage
|
| 104 |
-
|
| 105 |
-
This model uses FastAI format. To use it:
|
| 106 |
-
|
| 107 |
-
```python
|
| 108 |
-
from fastai.vision.all import load_learner
|
| 109 |
-
import pathlib
|
| 110 |
-
import platform
|
| 111 |
-
|
| 112 |
-
# Fix for cross-platform compatibility
|
| 113 |
-
if platform.system() == 'Windows':
|
| 114 |
-
pathlib.PosixPath = pathlib.WindowsPath
|
| 115 |
-
|
| 116 |
-
# Load the model
|
| 117 |
-
model = load_learner('model.pkl')
|
| 118 |
-
|
| 119 |
-
# Make prediction
|
| 120 |
-
prediction, pred_idx, probs = model.predict(image)
|
| 121 |
-
print(f"Prediction: {prediction}")
|
| 122 |
