Setting Up the AI Pneumonia Detection Model
Step 1: Install Python & Required Libraries
Ensure you have Python 3.8+ installed. Check by running:
python --version
If not installed, download it from: 👉 Download Python
Install the required libraries:
pip install tensorflow keras numpy pandas matplotlib seaborn glob
Step 2: Download the Dataset
Download and extract the Chest X-ray Pneumonia dataset from Kaggle: 👉 Dataset Link
Place the dataset inside your working directory:
/data/chest_xray/
Step 3: Run the Model
Execute the script to start pneumonia detection:
python pneumonia_detection.py
How Does the AI Pneumonia Detection Model Work?
1. Image Preprocessing & Augmentation
- Loads X-ray images and applies data augmentation (flipping, zooming, rescaling) for better training.
- Uses
ImageDataGeneratorto enhance model generalization.
2. Deep Learning with VGG16
- Uses VGG16 as a feature extractor.
- The final classification layer distinguishes between normal and pneumonia cases.
3. Model Training & Evaluation
- The model is trained using Binary Cross-Entropy Loss.
- Uses Exponential Decay Learning Rate for efficient optimization.
- Evaluates performance using accuracy scores and confusion matrices.
4. Real-Time Pneumonia Detection
- After training, the model can classify new X-ray images as normal or pneumonia.
Running Pneumonia Detection in Real-Time
1. Running the Model
To start classifying X-ray images, run:
python pneumonia_detection.py
2. Evaluating Model Performance
Check model accuracy using:
accuracy = model.evaluate(test_ds, 624)[1]
print("Model Accuracy:", accuracy)
3. Classifying New X-Ray Images
Upload an X-ray image and run prediction:
img = load_img('xray_image.jpeg', target_size=(150, 150))
img_array = img_to_array(img) / 255.0
img_array = np.expand_dims(img_array, axis=0)
prediction = model.predict(img_array)
result = "Pneumonia Detected" if prediction > 0.5 else "Normal"
print(result)
Customizing & Fine-Tuning the Model
1. Fine-Tuning VGG16 for Better Accuracy
If you want higher accuracy, unfreeze more layers in VGG16 and retrain:
for layer in model.layers:
layer.trainable = True
2. Train on a Custom Medical Dataset
- Replace the dataset with your own collection of X-ray images.
- Modify the dataset path in the script.
3. Deploy as a Web API for Healthcare Apps
- Use Flask or FastAPI to deploy the AI model as a REST API.
- Allow hospitals to upload X-ray images and receive AI-based diagnoses.
