🧠 Backpropagation in Convolutional Neural Networks (CNNs)

CNN

🌟 What is it?

This repository provides an in-depth exploration of Backpropagation in Convolutional Neural Networks (CNNs). It covers the architectural details of CNNs, the process of backpropagation in various layers (convolutional, pooling), and the mathematical foundations behind the backpropagation algorithm. The project includes practical examples, experiments, and a detailed breakdown of CNN components.

🎯 Why do we do it?

CNNs are the cornerstone of modern computer vision tasks such as image classification, object recognition, and segmentation. Understanding how backpropagation works within CNNs is crucial for optimizing and improving model performance. This project aims to demystify the backpropagation process, helping students and professionals gain a deep understanding of how CNNs learn from data.
