The Generator's aim is to create new fake data samples that are indistinguishable from real data samples in the training set Photo by TowardsDataScience. Generative Adversarial Networks includes a generator model which is capable of generating new plausible fake samples that can be considered to be coming from an existing distribution of samples and a discriminator model that would classify the given sample as real or fake

Abstract. Recently GAN generated face images are more and more realistic with high-quality, even hard for human eyes to detect. On the other hand, the forensics community keeps on developing methods to detect these generated fake images and try to ensure the credibility of visual contents Generative adversarial networks (GANs) enable computers to learn complex data distributions and sample from these distributions. When applied to the visual domain, this allows artificial, yet photorealistic images to be synthesized. Their success at this very challenging task triggered an explosion of research within the field of artificial intelligence (AI), yielding various new GAN findings.

Generative Adversarial Networks (GANs): An Overview

Fulfillment lies in the creating something by Abhinav

It is becoming increasingly easy to automatically replace a face of one person in a video with the face of another person by using a pre-trained generative adversarial network (GAN). Recent public scandals, e.g., the faces of celebrities being swapped onto pornographic videos, call for automated ways to detect these Deepfake videos. To help developing such methods, in this paper, we present. the use of generative adversarial networks (GAN), which are generative models that learn the distribution of data without supervision. GANs are an updated framework for estimating generative models using an adversarial approach in which two models are trained at the same time.
