- # 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

27
- ## Intended Uses & Limitations
28
-
29
- ⚠️ **Important**: This model is for research and educational purposes only. It should **NOT** be used for actual medical diagnosis without proper clinical validation and oversight by qualified medical professionals.
30
-
31
- ### Intended Uses
32
- - Research and development in medical AI
33
- - Educational purposes for learning about medical image classification
34
- - Proof-of-concept applications with proper disclaimers
35
- - Academic studies and benchmarking
36
-
37
- ### Limitations
38
- - Not clinically validated
39
- - Should not replace professional medical diagnosis
40
- - May have biases based on training data
41
- - Performance may vary on different populations or imaging conditions

55
- ## 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

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
- ```
