| # SPSD-Variants-opsd |
|
|
| Grounded on-policy self-distillation (OPSD) teacher-context dataset over **45 |
| board-game rule variants** (5 families × 9: connect4, domineering, |
| simplified_first_attack, simplified_othello, tic_tac_chess), derived from |
| trained MuZero/EfficientZero checkpoints (plan-528 v2). |
| |
| Each row is a decision-state task (a move choice or one of six auxiliary |
| state-QA tasks). The **`privileged_context`** is the teacher signal: **grounded |
| natural-language reasoning** that discovers the best move over the tempting |
| alternative and verifies it against the opponent's best reply, grounded in fresh |
| MuZero-net values that choose the wording but are **never printed**, and never |
| naming the search engine. The student-facing `prompt`, the `completion`, and the |
| `target` are unchanged from the underlying pools — only `privileged_context` |
| carries the grounded reasoning. |
|
|
| ## Contents |
|
|
| Files are gzip-compressed JSON Lines (`datasets` loads `.jsonl.gz` transparently). |
|
|
| | file | rows | purpose | |
| |---|--:|---| |
| | `train.jsonl.gz` | 213,406 | training split (170,725 move + 42,681 state-QA) | |
| | `frozen_probes/move.jsonl.gz` | 6,840 | held-out move probe (disjoint from train) | |
| | `frozen_probes/state_qa.jsonl.gz` | 40,841 | held-out six-task state-QA probe | |
| | `manifest.json` | — | full provenance, per-variant counts, balance, census fingerprint | |
|
|
| Per-family subsets are obtained by filtering `metadata.game_name` / |
| `metadata.family` (the five families are connect4, domineering, |
| simplified_first_attack, simplified_othello, tic_tac_chess). |
| |
| State-QA tasks (six): `occupancy`, `legality`, `threat_count`, |
| `legal_action_count`, `legal_action_enumeration`, `successor_state`. |
|
|
| ## Row schema |
|
|
| - `prompt` — student-facing board task (chat messages). |
| - `completion` — `Final answer: \boxed{…}`. |
| - `privileged_context` — grounded teacher reasoning + the boxed answer (teacher-only). |
| - `target` / `accepted_answers` — verifier + canonical answer. |
| - `metadata` — `task`, `game_name`, `decision_state_hash`, checkpoint provenance |
| (path/alias/SHA/env-step, algorithm, `num_simulations`, backend), and |
| `replay_evidence_horizon` (`rich` vs a conservative-fallback mode). |
|
|
| ## Provenance & method |
|
|
| - Sources: the trained `simplified5` othello-variant EfficientZero checkpoints; |
| 36 variants via `random-prefix-full-game` checkpoint self-play, 9 via |
| exhaustive real-env enumeration. |
| - Grounding: one fresh **50-simulation** MCTS search per decision state; a |
| separation gate (min root gap 0.05) refuses a distinction the root value does |
| not support and falls back to conservative prose (no row is ever dropped). |
| - Move coverage: ~54% rich grounded traces, ~46% conservative fallback. |
| - Seed 0. Verified corpus-wide: **no** raw search stats or engine names leak into |
| `privileged_context`; state-QA rationales are array-free. |
|
|
| ## Caveats |
|
|
| - **Text only** (`tokenizer_hash=not_tokenized`): tokenize and build the |
| OPSD-ready rows for your trainer. |
| - 6 connect4 variants (`exact_four`, `holey_four`, `no_center_opening`, |
| `one_diagonal_disabled`, `orthogonal_only`, `outer_opening`) carry a declared |
| `legality` shortfall (positive-skewed legality QA — illegal-handle states are |
| rare there); the pooled answer-class balance stays ≤ 0.65. |
| - Global per-task counts are balanced per family, not equal across the corpus |
| (reported, not enforced). |
