SymmAdapt: Symmetrical Flow Matching for Source-Free Domain Adaptation in Medical Image Segmentation
Paper β’ 2608.22532 β’ Published
Weights for SymmAdapt: source-free domain adaptation of a SymmFlow (SymmFMSD) segmenter.
Code: github.com/tal-grossman/SymmAdapt_public
These files are the paper MRIβCT run (CHAOS MRI β BTCV CT, four organs: spleen, kidneys, liver).
| File | What it is |
|---|---|
source_mri_best.pt |
Source model trained on labeled MRI (Phase I) |
gst_mri_to_ct_best.pt |
After generative self-training on unlabeled CT (Phase III) |
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 β they are PyTorch trainer checkpoints (ema_state_dict).
