The main issue in NICE-GAN is the coupling of translation with discrimination along the encoder, which could incur training inconsistency when we play the min-max game via GAN. To tackle this issue, we develop a decoupled training strategy by which the encoder is only trained when maximizing the adversary loss while keeping frozen otherwise. The Information Maximizing GAN, or InfoGAN for short, is an extension to the GAN architecture that introduces control variables that are automatically learned by the architecture and allow control over the generated image, such as style, thickness, and type in the case of generating images of handwritten digits.

InfoGAN is a type of generative adversarial network that modifies the GAN objective to encourage it to learn interpretable and meaningful representations. This is done by maximizing the mutual information between a fixed small subset of the GAN's noise variables and the observations. Generative models. This post describes four projects that share a common theme of enhancing or using generative models, a branch of unsupervised learning techniques in machine learning. In addition to describing our work, this post will tell you a bit more about generative models: what they are, why they are important, and where they might be. The Structure of InfoGAN A normal GAN has two fundamental elements: a generator that accepts random noises and produces fake images, and a discriminator that accepts both fake and real images and identifies if the image is real or fake.

Claude Shannon's 1948 paper defined the amount of information which can be transferred in a noisy channel in terms of power and bandwidth. A new research study conducted by Xi Chen and team proposes a GAN-styled neural network which uses information theory to learn "disentangled representations" in an unsupervised manner. InfoGAN The way InfoGAN approaches this problem is by splitting the Generator input into two parts: the traditional noise vector and a new "latent code" vector. The codes are then made meaningful by maximizing the Mutual Information between the code and the generator output. Theory This paper describes InfoGAN, an information-theoretic extension to the Generative Adversarial Network that is able to learn disentangled representations in a completely unsupervised manner. InfoGAN is a generative adversarial network that also maximizes the mutual information between a small subset of the latent variables and the observation. We derive a lower bound to the mutual information. generator becomes G (z;c ). However, in standard GAN, the generator is free to ignore the additional latent code c by nding a solution satisfying P G (x jc) = P G (x ). To cope with the problem of trivial codes, we propose an information-theoretic regularization: there should be high mutual information

InfoGAN, short for Information Maximizing Generative Adversarial Networks, is a powerful machine learning technique that extends the capabilities of traditional Generative Adversarial Networks (GANs). While GANs are known for generating high-quality synthetic data, they lack control over the specific features of the generated samples. Mutual Information. InfoGAN stands for information maximizing GAN. To maximize information, InfoGAN uses mutual information. In information theory, the mutual information between X and Y, I(X; Y ), measures the "amount of information" learned from knowledge of random variable Y about the other random variable X.
Generative Adversarial Networks, or GANs, are deep learning architecture generative models that have seen wide success. There are thousands of papers on GANs and many hundreds of named-GANs, that is, models with a defined name that often includes "GAN", such as DCGAN, as opposed to a minor extension to the method.Given the vast size of the GAN literature and number of models, it can be, at. InfoGAN is designed to maximize the mutual information between a small subset of the latent variables and the observation. A lower bound of the mutual information objective is derived that can.

1. Introduction. InfoGAN was introduced by Chen et al.[1] in 2016. On top of GAN having a generator and a discriminator, there is an auxiliary network called the Q-network. The approach is motivated from the information-theoretic point of view and is based on minimizing the mutual information between the latent codes and the generated images.. For completeness it would be nice to have V(D,G) formulated in terms of x,c,z: it is not 100% clear from equation (1).. However, in pure GAN the learning algorithm.
