What are GANs?
GAN is a type of machine learning model called a neural network, specially designed to imitate the structure and function of a human brain. For this reason, neural networks in machine learning are sometimes referred to as artificial neural networks (ANNs).
GANs, introduced by Ian Goodfellow and his colleagues in 2014, are a type of generative model that consists of two neural networks: a generator and a discriminator. The generator network takes a random noise vector as input and produces a synthetic data point, while the discriminator network evaluates the generated data point and tells the generator whether it’s realistic or not.
The generator’s goal is to produce data points that are indistinguishable from real data, while the discriminator’s goal is to correctly identify generated data points. The training process of GANs involves a two-player game between the generator and discriminator. The generator tries to produce realistic data points, while the discriminator tries to correctly classify them as real or fake. This adversarial process leads to both networks improving in performance, resulting in highly realistic generated data. This technology is the basis of deep learning, a subcategory of machine learning (ML) capable of recognizing complex patterns in varying data types such as images, sounds, and text.
Generative Models in AI: A Comprehensive Comparison of GANs and VAEs
The world of artificial intelligence has witnessed a significant surge in the development of generative models, which have revolutionized the way we approach tasks like image and video generation, data augmentation, and more. Among the most popular and widely used generative models are Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs).
GANs consist of a generator and a discriminator network that compete against each other in a two-player minimax game. The generator tries to generate realistic samples from random noise, while the discriminator aims to distinguish between real and fake samples. On the other hand, VAEs are probabilistic models that learn a latent representation of the input data. In this article, we’ll delve into the intricacies of GANs and VAEs, exploring their key differences, similarities, and real-world applications.
