CIFAR-10 Image Classification with CNN Ensemble 🖼️🤖

This project implements an advanced image classification system using Convolutional Neural Networks (CNNs) on the CIFAR-10 dataset. By combining three distinct CNN architectures through ensemble methods, we achieve robust and accurate image classification results. 🎯

Overview 📋

The project consists of:

• 🧠 Three CNN models with different architectures
• 🔄 Advanced data augmentation techniques
• 🤝 Ensemble methods (Simple Averaging and Majority Voting)
• 🌐 A Streamlit web interface for real-time predictions
