StyleGAN2-ADA: grayscale chest X-ray, from scratch
Source: NVlabs/stylegan3 (StyleGAN2 architecture only). Two GPUs, global batch 32. Dataset: Purino/chest-xray-pneumonia-256-fullframe-gray; train only, original class proportions. Each checkpoints/nimg-* directory contains a complete two-rank resume bundle and a fixed 4x4 sample grid. network.pkl is an NVIDIA-compatible inference snapshot. Full resume also requires BOTH rank-*.pt files. No pretrained initialization. No FID/KID or automatic best-checkpoint selection. Loss does not rank image quality. Review samples and summary.json across checkpoints. Source/license archive, environment, config, statistics and integrity manifest accompany every checkpoint. Samples are synthetic research outputs; diagnostic correctness is not established.
