Creating a Convolutional Autoencoder in Keras: A Step-by-Step Guide

When delving into the world of deep learning, Convolutional Autoencoders present a powerful tool for dimensionality reduction and feature learning. Implementing these in Keras, a high-level neural networks API, is both intuitive and efficient. Here's how you can build one step-by-step.

Step 1: Import Necessary Libraries
Begin by importing the essential libraries. Keras, along with its components, will be at the heart of our model.

Step 2: Define the Model Architecture
A Convolutional Autoencoder consists of two parts: the encoder and the decoder.

Encoder
This part compresses the input image into a latent space representation.
