Let P and Q be sets of points in Rd. "! piq · PyPI The Fréchet inception distance (FID) is a metric used to assess the quality of images created by a generative model, like a generative adversarial network (GAN). 1 , where it combines outputs from \(1\times 1\) , \(3\times 3\) and \(5\times 5\) convolutions as well as a maximum pooling operation. 添加评论. Lower is … classifier_fn: A function that takes images and produces activations based on a classifier. Both metrics measure the difference in the generated and training distributions in the representation space of an InceptionV3 network pretrained on ImageNet. the Kernel Inception Distance . Kernel Inception Distance (KID) was proposed as a replacement for the popular Frechet Inception Distance (FID) metric for measuring image generation quality. Data-efficient GANs with Adaptive Discriminator Augmentation We illustrate by examples that this makes diagnosis of model performance difficult. We extend FID by relaxing the Gaussian hypothesis of the related inception features and extend it for non-Gaussian, multimodal distributions. A simple example of a kernel is the Gaussian kernel K(x, y)= exp(kx yk 2 ˙2). generated_images: Generated images to use to compute Kernel Inception distance. The Fréchet distance between two multivariate normal distributions having means μX, μY and covariance matrices ΣX, ΣY is shown to be given by d 2 = |μ X − μ Y | 2 + tr (Σ X + Σ Y − 2 (Σ X Σ Y) 1 2). As an alternative to these automatic metrics, a human-in-the-loop evaluation of model quality has been described Zhou2019HYPE . Kernel (Binkowski et al.´ ,2018) Inception Distances (FID and KID).
