The dataset viewer is not available because its heuristics could not detect any supported data files. You can try uploading some data files, or configuring the data files location manually.

Codebooks — canonical store
All k-means codebooks live here, organized by what they are, not which experiment built
them: codebooks/<dataset>/<encoder+feature>_<geometry>[_<build-variant>]/<prop>_img<S>_k<K>.pt.
The old per-task locations under dumps/ are symlinks into this tree (moved 2026-08-27), so
historical scripts keep working; new scripts should reference these paths directly.
Canonical sets (what the current method uses)
| dataset | dir | contents | role |
|---|---|---|---|
| iPAD | ipad/dinov2abs_euc/ |
16 props, DINOv2 ViT-S/14 abs tokens, img224, K8192 (+512/1024/4096 for r01/r04/s01) | the board abs-abs codebooks |
| PhysAD | physad/dinov2abs_euc/ |
22 subsets, DINOv2 ViT-S/14, img448, K512+K8192 | the PhysAD abs-abs codebooks (0.979 result) |
Abs codebooks are window-independent, and since 2026-08-27 _validate_cross_codebook_meta
skips the num_frames/context_length checks for abs-kind artifacts — reuse them across
window shapes directly. (The historical *_metarelaxed.pt meta-nulled copies under
dumps/t034m_window/codebooks/ predate that fix and are task debris, not a set.)
Only real, buildable sets live in this tree; task-specific shims stay in the task's dump dir.
Other sets
| dir | contents |
|---|---|
ipad/dinov2abs_cos/, ipad/dinov3abs_{euc,cos}/ |
geometry / DINOv3 screens |
ipad/vjepa21tub_euc/ |
V-JEPA2.1 patch-embed tubelet, img224; mixed sklearn + cuVS-sampled builds (_cuvs/_cuvsFULL filename suffixes) |
ipad/vjepa21tub_euc_cuvsFULL/ |
tubelet, cuVS full-pool k-means (incl. fs8/) — the t034a set |
ipad/vjepa21tub_euc_fullpool/, ipad/vjepa21tub_legacy_t033/ |
small legacy sets |
physad/vjepa21tub_euc/ |
tubelet img448 K512, nf6c4fs4st2-named (t034 canonical arm) |
physad/vjepa21tub_euc_cuvsFULL/, physad/vjepa21tub_euc_early/ |
cuVS rebuild / earlier build of the same |
physad/vjepa21tub_probes/ |
one-off geometry/ctxref probe artifacts |
Building
One builder for everything: scripts/analysis/ipad/build_shallow_tubelet_codebook.py
(sgad-ipad repo) — --timm-model <timm id> for DINO abs features, --variant for the
V-JEPA tubelet; --fast-extract --gpu-kmeans --stream-kmeans is the standard invocation
(see scripts/sweeps/ipad/t034c_absabs_codebooks.sh for a worked example). Do not use
the legacy scripts/data/ipad/build_codebook.py (sklearn MiniBatchKMeans degenerates at
large K). Each .pt stores centroids + a meta dict with full build provenance
(encoder, window, K, geometry, data version).
Sharing
Public mirror: https://huggingface.co/datasets/sgad-iclr/sgad-codebooks — the canonical sets
(ipad/dinov2abs_euc, physad/dinov2abs_euc, ipad/vjepa21tub_euc_cuvsFULL,
physad/vjepa21tub_euc) plus this README, same layout. Screens / legacy / probe sets stay
local-only. Download (no token or account needed) to bulk storage — codebook paths are passed
explicitly (config/CLI), so the tree can live anywhere, just not inside the repo / a quota'd home:
uvx hf download sgad-iclr/sgad-codebooks --repo-type dataset --local-dir /path/on/bulk/storage/codebooks
After adding or rebuilding a canonical set, re-sync it (and this README) to the mirror:
hf upload sgad-iclr/sgad-codebooks <local-dir> <same-relative-path> --repo-type dataset
On this node, $SCRATCH top level is traversal-only for others; directories in this tree are
o+rx, so any file here is readable by exact path or by listing from codebooks/ down.
