🌟 Introduction

Convolutional Neural Networks are powerful deep learning models used for image processing, computer vision, and more. This repository demonstrates:

• Applying zero-padding to input images.
• Performing a single convolution step.
• Conducting forward propagation in a convolutional layer.
• Implementing pooling operations (max and average pooling).

These examples are implemented in Python using NumPy and Matplotlib, providing a step-by-step guide to the foundational aspects of CNNs. 📊📸

🔍 Core Concepts

1️⃣ Zero-Padding

Zero-padding adds borders of zeros around input images to preserve spatial dimensions during convolution operations.

2️⃣ Single-Step Convolution

A single convolution step applies a filter (weight matrix) to a slice of the input data, producing an output scalar.

3️⃣ Forward Propagation

This involves applying filters and biases across the input data to produce feature maps for the next layer.

4️⃣ Pooling Layers

Pooling layers downsample feature maps, reducing their size while retaining important information. Supported modes: max pooling and average pooling.
