QuAR checkpoints

Quantized checkpoints for QuAR, the code for Test-Time Adaptation of Quantized ViTs via Single-Pass Quantizer-Aligned Recalibration.

23 files: PTQ4ViT and AdaLog quantizations of ViT-B/16, DeiT-B, ViT-S and ResNet-50 from W3A3 to W8A8, on ImageNet, CIFAR-10/100 and DomainNet-126, plus the full-precision DomainNet-126 model the last of those are built from.

Use

git clone https://github.com/chahh9808/QuAR && cd QuAR
bash tools/fetch_artifacts.sh

The script puts them in checkpoints/ and checks each one against the SHA-256 in artifacts/MANIFEST.tsv, which also records what produced it. AdaLog's own ImageNet checkpoints and the two source CIFAR ViTs are not mirrored here; the script prints where to get them.

Provenance

Every file is a quantization, that is a modification, of an Apache-2.0 model:
