Benchmarking stylegan_plus
- [X] ResNet
- [X] image loss using logcosh (VGG16 perceptual model)
- [X] MS-SIM loss (VGG16 perceptual model)
- [X] LPIPS loss (VGG16 perceptual model)
- [ ] floating point 16bit
- [ ] face mask
- [ ] tiled dlatents
Status:
- [X] Stochastic clipping and best latent
- [ ] Serve resnet and/or stylegan_encoder in different standalone processes

Conclusion: Seems like the difference is not prominent. Run time was also not drastically improved ,but I should try testing with less iterations. I would choose a variation of the
