7.1 Autoencoders and Variational Autoencoders (VAEs)
In this section, we delve into two powerful unsupervised learning techniques: Autoencoders and Variational Autoencoders (VAEs). These neural network architectures have revolutionized the field of machine learning by enabling efficient data compression, feature extraction, and generative modeling. We'll explore their underlying principles, architectural designs, and practical applications across various domains.
7.1.1 Autoencoders: An Overview
An autoencoder is a sophisticated neural network architecture designed for unsupervised learning. Its primary objective is to learn an efficient, compressed representation (encoding) of input data and subsequently reconstruct the input from this condensed ...
