MOSAIC NeurIPS 2026 β€” results

Paper-scoped scientific backup, organized as:

molecular/<dataset>/<variant>/...
non-molecular/<dataset>/<variant>/...
metadata/...

Datasets: GuacaMol (guacamol), MOSES (moses), COCONUT (coconut2), GEOM-Drugs disjoint split (geom-drugs), Macrocycle (macrocycle), Proteins (proteins), Planar (planar), SBM (sbm), SSBM (ssbm), and RSBM R=4 original/connected populations (rsbm-r4-original, rsbm-r4-connected).

Variants HAC-R, HAC-FR, MC-R, MC-FR, PH-R, and PH-FR denote the paper's HDT variants. SENT, HSENT-HAC-R, HSENT-MC-R, and HDTC-R retain their distinct meanings. Shared data/references are stored once under shared; HAC, MC, PH, HDTC, and Louvain in the data repository identify a reusable cache family, not an additional trained model.

Names and settings

Checkpoint names follow:

<dataset>_<variant>_<backbone>_steps<N>_batch<B>_ctx<L>_lr<rate>[_tau<T>]_seed<S>[_online|_precomputed]_last.ckpt

For example:

molecular/guacamol/HAC-FR/guacamol_HAC-FR_gpt2-xs_steps100000_batch256_ctx512_lr0.0006_tau4_seed42_last.ckpt

batch is the effective global batch including devices and gradient accumulation. tau is the HAC community-size threshold and is omitted for methods that do not use HAC. seed in the run name is the training seed; evaluation seeds are separate subdirectories. Full settings and exact paper locations appear in metadata/neurips2026_run_catalog.json; frozen training configurations are in the results repository alongside each run. Different context lengths, thresholds, schedules and model sizes remain distinguishable.

Data paths also identify the cached population, split/shard, coarsening family and threshold where applicable. Results are grouped by run, evaluation protocol, motif and evaluation seed. Cross-dataset figure/source metadata lives under metadata/.

Scope and integrity

This backup follows manuscript revision 559f541889ed6156d5af3e801055f25bc74cc3d1. It is not an archive of every exploratory experiment. Only LAST checkpoints are included; optimizer and training state are retained. Conditional results are motif-conditioned only. Historical HAC-FR-Top PGD files accidentally included in the previous selection are explicitly excluded because that variant is absent from this paper revision.

All scientific payloads are preserved byte-for-byte. Standardized names apply to repository paths. Frozen configurations, checkpoint fields and provenance may still contain original experiment labels or paths; changing those would alter the research artifacts. The manifest maps each standard path back to its exact original path and records its SHA256. Historical Git commits are retained; the previous layout is removed from the current repository tree after verification.

Restore

Download neurips2026_backup_index.json from the results repository and restore_neurips_backup.py from any of the three repositories. Install huggingface_hub, then run:

python restore_neurips_backup.py --index neurips2026_backup_index.json --destination /path/to/backup

The default produces <destination>/<data|checkpoints|results>/<standard repository path>. To reconstruct the original code-compatible project tree, add --layout original. Original absolute paths inside some frozen manifests may require an equivalent project-root alias. Use --category data|checkpoints|results and repeatable --path <standard-or-original-path> to select a subset. Downloads are revision-pinned and checksum-verified; identical existing files are skipped and different existing files are never overwritten.

Repositories: data, checkpoints, results.
