kernel inception distance

Fréchet Distance 又被稱為 Wasserstein-2 distance ，本身用來量測兩個曲線的相似程度，更具體的例子是比較兩個物體在不同時間的軌跡相似的程度。. Another approach is to train a classier between the real and fake distributions and to use its accuracy on a test set as a proxy for the quality of the samples [ 11 ,17 ]. TorchMetrics in PyTorch Lightning — PyTorch-Metrics 0.8.2 … Standard evaluation metrics for GANs such as Inception Scores, Frechet Distance or Kernel Distance are available inside TF-GAN Evaluation. We showcase this inadvertence in Figure1: here FID and KID are insensitive to the global structure of the data distribution. The key aspect of the kernel distance developed here is its interpretation as an L2 distance between probability measures or various shapes (e.g. point sets, curves, surfaces) embedded in a vector space (specifically an RKHS). This structure enables several elegant and efficient solutions to data analysis problems. In experiments, the MMD GAN is able to employ a smaller critic network than the Wasserstein GAN, resulting in a simpler and faster-training algorithm with matching performance. parent – Flag to control … Both of them can be interpreted as a distance between two distributions P r and P f , which represent real and fake (generated) data transported into a feature (inception) space via the Inception V3 network [31] … kernel_size – The side-length of the sliding window used in comparison. Being an integral probability metric, the MMD benefits from training strategies recently developed for Wasserstein GANs. Salimans2016IS, Fréchet Inception Distance (FID) Heusel2017FID, Kernel Inception Distance (KID) Binkowski2018KID, and Precision/Recall Sajjadi2018PR; Kynkaanniemi2019; Naeem2020PR. Both metrics measure the difference in the generated and training distributions in the representation space of an InceptionV3 network pretrained on ImageNet.
