OneDiffRec semantic-ID codebooks
Item semantic-ID (SID) tables and the trained tokenizers behind them, from the OneDiffRec grid on Amazon Reviews (Industrial_and_Scientific and Office_Products). Three tokenizers, each at 3/4/5 codebooks x 128/256/512 codes:
MQ: TokenRec parallel multi-codebook tokenizer (rq/mq.py, 10000 epochs, seed 2024), the fixed implementation (commit 7ae3512, tables rebuilt 2026-10-16).rqkmeans: residual k-means.rqvae: RQ-VAE (rq/rqvae.py, 10000 epochs, seed 2024).
Layout
<dataset>/tokenizers/tables.json settings used to build all tables
<dataset>/tokenizers/<method>_<D>codebook_<K>/
<Dataset>.*index*.json native SID table: item index -> ["<a_i>", "<b_j>", ...]
done.json build record: collisions, sha256, geometry source
geometry/ last-codebook centroids, residual vectors, item ids
(MQ: also mq_model.pth, the trained tokenizer)
checkpoints/.../best_collision_model.pth RQ-VAE only: the model the table comes from
zcr-*.index.json rqkmeans only: zero-collision table
tokenizer.log, zcr.log
<dataset>/zcr/<method>_<D>codebook_<K>/
index.json zero-collision-repair (ZCR) SID table
native_codes.npy, zcr_codes.npy, native_index.json, item_ids.json
final_centroids.npy, last_stage_vectors.npy, manifest.json, stats.json
Native tables let several items share one SID; ZCR moves colliding items to the nearest free last-level code so every item has a unique SID. Absolute paths inside manifests and logs refer to the original training cluster.
