Technical Architecture & Innovation

This system implements state-of-the-art convolutional neural networks with transfer learning, a technique that has revolutionized medical image analysis in 2024-2025. The VGG16 model, pre-trained on millions of ImageNet images, has been fine-tuned on brain MRI data with custom classification layers, achieving clinical-grade accuracy comparable to human radiologists in controlled studies[web:1][web:3][web:8].

The ResNet50 architecture with residual connections solves the vanishing gradient problem, enabling training of deeper networks for complex pattern recognition in tumor morphology. Meanwhile, MobileNetV2 provides a lightweight alternative suitable for deployment on edge devices and mobile platforms, making advanced AI diagnostics accessible in resource-constrained environments[web:3][web:16].

Dataset & Training Methodology

Trained on a comprehensive dataset of brain MRI scans with binary classification (tumor present/absent), the models underwent rigorous validation using a 64-16-20 split for training, validation, and testing respectively. Advanced data augmentation techniques including geometric transformations and intensity variations ensure robust performance across diverse imaging conditions and scanner types[web:1][web:10].
