SymmAdapt

SymmAdapt checkpoints (abdomen MRI → CT)

Weights for SymmAdapt: source-free domain adaptation of a SymmFlow (SymmFMSD) segmenter.

Code: github.com/tal-grossman/SymmAdapt_public

These files are the paper MRI→CT run (CHAOS MRI → BTCV CT, four organs: spleen, kidneys, liver).

Load them with the public repo (bash scripts/download_checkpoints.sh, then scripts/run_eval.sh). Do not expect a Hugging Face from_pretrained API — they are PyTorch trainer checkpoints (ema_state_dict).

Not included here:

• LatFM init: ocaetas/SymmFlow (LatFM_coco_beta6.0.pt)
• SD VAE: stabilityai/sd-vae-ft-mse (pulled at runtime)
• Images: DFG / BTCV / CHAOS
