With Data Augmentation:
- 2 experiments (MSE and DSSIM Loss) for each of the following architectures:
- Shallow residual autoencoder (full-pre)
- Shallow residual autoencoder (full-pre) + L2 reg.
- Skip connection autoencoder
- Skip connection autoencoder + L2 reg.
- Myronenko Autoencoder
- RESIDUAL-UNET (proposed new improved architecture)
- 2 experiments (MSE and DSSIM Loss) for each of the following architectures:
-
Without Data Augmentation:
- MSE Loss
- Shallow residual autoencoder (original)
- Shallow residual autoencoder (full-pre)
- Shallow residual autoencoder (full-pre) + L2 reg.
- Skip connection autoencoder
- Myronenko Autoencoder
- Myronenko Autoencoder + L2 reg.
- MSE Loss
