The Shining starring Jim Carrey (2019)
1) Deepfakes (a portmanteau of "deep learning" and "fake") are media that take a person in an existing image or video
and replace them with someone else's likeness using artificial neural networks. They often combine and superimpose existing media onto source media using machine learning techniques known as
autoencoders and generative adversarial networks (GANs). Deepfakes rely on a type of neural network called an autoencoder. These consist of an encoder, which reduces an image to a lower
dimensional latent space, and a decoder, which reconstructs the image from the latent representation. Deepfakes utilize this architecture by having a universal encoder which encodes a person in
to the latent space. The latent representation contains key features about their facial features and body posture. This can then be decoded with a model trained specifically for the target. This
means the target's detailed information will be superimposed on the underlying facial and body features of the original video, represented in the latent space.
2) This video (made by youtube user "Ctrl Shift Face") is replacing Jack Nicholson's face with Jim Carrey's face in the movie "Shining" (1980). It's the most advanced deepfake video today.
