# DeepShopper frozen splits (mapper / reward)

Deterministic, leakage-safe train/test splits used across DeepShopper. Split assignment is a
stable `sha1(need)` hash (same need never crosses train/test; reproducible). Gender-stratified.
Contains: `fashionrec_task1_mapper/{train,test}`, `amz_mapper/{female,male,other}.{train,test}`
(need→plan), and `amz_reward_bundle/{female,male,other}.{train,test}` (need→outfit, reward
positives). Generated by `scripts/make_mapper_reward_splits.py`. Code: https://github.com/clijo/reco-rl (branch outfit_bundle).
