What are deepfakes?
Deepfakes are manipulated media, including videos, images, or audio, that have been created or altered using artificial intelligence (AI) and deep learning techniques. The term “deepfake” is derived from the combination of “deep learning” (a subset of machine learning) and “fake.”
Deepfakes leverage powerful AI algorithms, particularly generative adversarial networks (GANs), diffusion models, or AI algorithms based on neural radiance fields (NeRF), to replace or superimpose the original content with new content that appears realistic but is actually synthesised or manipulated. These algorithms analyze and learn from large datasets of images or videos to understand patterns, features, and context. They then generate new content by combining and altering elements from the source material.
