WebIn this study, the hyperspherical VAE is used for the CVAE, which is termed as the hyperspherical CVAE (S-CVAE). The network architecture of the S-VAE is nearly identical to that of the N-VAE; the difference is that the S-VAE uses a vMF distribution rather than a normal distribution. WebIn [4], the authors propose a hyperspherical parameterization of the VAE using a von Mises-Fisher distribution, demonstrating the improved results over the especially bad …
