TL;DR. Synthetic media in which a person in an existing image or video is replaced with someone else's likeness.

Technical Definition

Synthetic media in which a person in an existing image or video is replaced with someone else's likeness.

How it works

Deepfakes are created using deep learning techniques, typically generative adversarial networks (GANs), to produce highly realistic manipulated media. While they have creative applications, concerns exist regarding misinformation, fraud, and privacy. Detection of deepfakes is an active area of research.

Related Concepts

• Generative Adversarial Network (GAN) — Two neural networks — a generator and discriminator — compete against each other to produce increasingly realistic synthetic data.
• Synthetic Data — Artificially generated data mimicking real-world properties, used for training augmentation or privacy protection.
• Generative AI — An AI field focused on creating models that can generate novel and complex content, such as text, images, audio, and video, that is coherent and original.
