Why is my GAN not converging?

A Why is my GAN not converging? GAN models do not converge. Instead, the generator and the discriminator models find a stable equilibrium (hopefully). The generator deceives the discriminator at some level (but not all the time) and the discriminator effectively classifies real and generated images (but not all the time). For more on this […]

How to Implement the Frechet Inception Distance (FID) From Scratch for Evaluating Generated Images

How to Implement the Frechet Inception Distance (FID) for Evaluating GANs

The Frechet Inception Distance score, or FID for short, is a metric that calculates the distance between feature vectors calculated for real and generated images. The score summarizes how similar the two groups are in terms of statistics on computer vision features of the raw images calculated using the inception v3 model used for image […]

How to Implement the Inception Score (IS) for Evaluating GANs

Generative Adversarial Networks, or GANs for short, is a deep learning neural network architecture for training a generator model for generating synthetic images. A problem with generative models is that there is no objective way to evaluate the quality of the generated images. As such, it is common to periodically generate and save images during […]

How to Implement Progressive Growing GAN Models in Keras

The progressive growing generative adversarial network is an approach for training a deep convolutional neural network model for generating synthetic images. It is an extension of the more traditional GAN architecture that involves incrementally growing the size of the generated image during training, starting with a very small image, such as a 4×4 pixels. This […]

How to Develop a CycleGAN for Image-to-Image Translation with Keras

The Cycle Generative Adversarial Network, or CycleGAN, is an approach to training a deep convolutional neural network for image-to-image translation tasks. Unlike other GAN models for image translation, the CycleGAN does not require a dataset of paired images. For example, if we are interested in translating photographs of oranges to apples, we do not require […]

A Gentle Introduction to CycleGAN for Image Translation

Image-to-image translation involves generating a new synthetic version of a given image with a specific modification, such as translating a summer landscape to winter. Training a model for image-to-image translation typically requires a large dataset of paired examples. These datasets can be difficult and expensive to prepare, and in some cases impossible, such as photographs […]

How to Develop a Pix2Pix GAN for Image-to-Image Translation

The Pix2Pix Generative Adversarial Network, or GAN, is an approach to training a deep convolutional neural network for image-to-image translation tasks. The careful configuration of architecture as a type of image-conditional GAN allows for both the generation of large images compared to prior GAN models (e.g. such as 256×256 pixels) and the capability of performing […]
