SAII-CLDM Data
This dataset package supports the official SAII-CLDM open-source implementation.
Payload files:
Pwavevelocity.mat
marmousi/marmousi_256_train.npz
overthrust/Overthrust_trueimp.mat
prepare_marmousi_256_train.py
vgg.pth
Pwavevelocity.mat is the official Marmousi velocity model file used by the default Stage 1 VQGAN multi-scale training config and the experimental Diffusers VQGAN trainer.
marmousi_256_train.npz is derived from the official Marmousi model and contains 256 x 256 log-velocity patches with flip and elastic-deformation augmentations. It is used by Stage 2 training and the experimental Diffusers LDDPM trainer.
Overthrust_trueimp.mat is the Overthrust benchmark file used by the evaluation code.
prepare_marmousi_256_train.py is a minimal data preparation script documenting the Marmousi-derived training data recipe. It expects Pwavevelocity.mat and writes the training .npz file.
vgg.pth is the LPIPS linear-weight checkpoint used by the VQGAN perceptual loss. The training code copies it to tmp/vgg.pth automatically when present in this data directory.
