Variational Autoencoders (VAEs) are complex models that have two parts - an encoder and a decoder - working together to generate new, realistic data points from learned patterns.

VAEs were first introduced in 2013 by Diederik P. Kingma and Max Welling, and have since become a popular type of generative model.

A VAE's encoder converts given input into a smaller and denser representation of the data, preserving only the essential features that the decoder needs to successfully reconstruct the original input.

VAEs excel in tasks like image and sound generation, as well as image denoising, thanks to their ability to encode input data into a lower-dimensional latent space.

This latent space is like the DNA of an organism, containing the fundamental elements of data that allow the model to regenerate the original information from this encoded essence.

VAEs can also be used for data compression, anomaly detection, and even drug discovery, showcasing their versatility across various domains.

With practical applications in image generation, data compression, and more, VAEs have come a long way since their emergence in the 1990s, and continue to be a popular choice for generative AI tasks.
