VerdictAD decision cache

Decision-model outputs and reference lists behind every number in VerdictAD: Few-Shot Anomaly Detection via Decision-Guided Refinement (paper, code).

With this cache, evaluate.py reproduces the VerdictAD results on any detector run without running the decision model (Clef-Flash 9B).

Contents

27 runs: MVTec AD, VisA and MVTec LOCO AD × 1/2/4-shot × three reference draws (seeds 42/43/44 for 1- and 2-shot, 42/43/45 for 4-shot); 49,095 test images in total.

refs/<dataset>_k<shots>_s<seed>/refs_<class>.json       the k normal references (paths relative to the dataset root)
decisions/<dataset>_k<shots>_s<seed>/<class>.json       one record per test image

Each record:

Field Meaning
img_path <class>/test/<type>/<file>, relative to the dataset root
anomaly 1 for an anomalous test image
z_free GVR logit, query image alone
z_ref GVR logit, query image against the 2×2 reference mosaic
boxes 32 windows (x0, y0, x1, y1) in [0, 1]: 16 crop windows, then the same 16 as red boxes
logits LVR logit of each window

The references come from the official SubspaceAD sampler at the given seed, and every detector in the paper uses them. LOCO paths follow the layout written by tools/prepare_loco.py; VisA paths follow the 1-class split.

Usage

huggingface-cli download sunsean/VerdictAD --repo-type dataset --local-dir verdictad_cache
python evaluate.py <detector_run> verdictad_cache/decisions/mvtec_k4_s42 --subspacead SubspaceAD

<detector_run> is a SubspaceAD run (patched to save maps) or a detectors.py output that uses refs/mvtec_k4_s42.
