| # MATS-SQL Bundle — Paper-Format Pipeline (iter1) |
|
|
| Full MATS multi-agent Text2SQL pipeline reproduced on BIRD-bench. Validators use the |
| **paper's `Feedback:` + `Conclude: correct/incorrect.` format** (not wrapper-tag). |
|
|
| ## Final BIRD-dev numbers (1524/1534 questions with usable db_path) |
| |
| | Config | planner@1 (T=0) | pipeline@1 (T=0) | oracle pass@8 | **trained selector EX** | |
| |---|---|---|---|---| |
| | PLANNER-only | **51.54%** | 51.54% | 70.80% | — | |
| | SFT-VF (paper validators) | 51.48% | 52.20% | 71.65% | **59.91%** | |
| | ORPO iter1 COLLAB | 51.08% | 51.81% | 71.19% | **59.97%** | |
| | ORPO iter1 INDEP | 51.74% | 52.59% | 71.95% | **60.31%** | |
| |
| All three pipelines converge to ~60% selector EX. Validator-internal ORPO gains |
| (COLLAB reward-acc +10/+17pp over INDEP) **do not translate to pipeline EX**. |

| ## Validator training reward accuracies (eval_dpo on test split) |
| |
| | Model | eval_loss | eval_rewards/accuracies | |
| |---|---|---| |
| | validator-sel-1B-orpo-iter1-collab-paper | 0.174 | **69.7%** | |
| | validator-sel-1B-orpo-iter1-indep-paper | 0.210 | 59.7% | |
| | validator-cond-1B-orpo-iter1-collab-paper | 0.148 | **89.7%** | |
| | validator-cond-1B-orpo-iter1-indep-paper | 0.163 | 72.0% | |
| |
| COLLAB > INDEP by +10pp (sel) and +17.7pp (cond) at the chosen-vs-rejected level, but |
| the gain doesn't propagate to end-to-end EX. See `HANDOFF_SELECTOR_TASK.md`. |
| |
| ## Hyperparameters |
| |
| - **SFT** (validator/fixer/selector): lr=2e-5 cosine, 2 epochs, bf16, completion-only loss. |
| - **ORPO** (paper §4.3): β=0.1, lr=8e-6 (1e-6 for val-sel-indep due to NaN), max_steps=400, max_grad_norm=0.5. |
| - **Rollout** (`run_pipeline_rollouts.py`): K=8 candidates per question, T=1.0, top_p=0.9. |
| - Fixer gated by `planner_exec_ok=False`. |
| |
| ## Reproduce |
| |
| ```bash |
| # 1. Generate paper-format validator SFT data (uses Qwen-2.5-72B as teacher) |
| python scripts/gen_planner_preds_for_validator.py --out data/planner_3B_greedy_bird_train.jsonl # ~15min |
| python scripts/gen_validator_sft_qwen72b.py --input data/planner_3B_greedy_bird_train.jsonl # ~7h |
| |
| # 2. Train paper-format validators |
| python scripts/train_sft_completion_only.py --base meta-llama/Llama-3.2-1B-Instruct \ |
| --data data/hf_val_sel_paper_v1 --chat_format llama3 --epochs 2 --lr 2e-5 |
| |
| # 3. Generate ORPO iter1 data (collab + indep) |
| python scripts/build_orpo_data.py --agent validator_sel --mode collab --K 4 --temperature 1.0 --max_questions 2000 |
|
|
| # 4. ORPO train (per recipe in recipes/iter1-paper/) |
| accelerate launch alignment-handbook/scripts/run_orpo.py recipes/iter1-paper/orpo-val-sel-collab-paper.yaml |
| |
| # 5. K=8 rollout eval on BIRD-dev |
| python scripts/run_pipeline_rollouts.py --input data/sft_bird_with_evidence_dev_text2sql.json \ |
| --K 8 --temperature 1.0 ... |
| |
| # 6. Selector EX |
| python scripts/compute_bestofn_with_selector.py eval_results/paper_*_passAt8_bird_dev.jsonl |
| ``` |
| |
| ## Open problem — see HANDOFF_SELECTOR_TASK.md |
| |
| Selector EX is **saturated at ~60%** across all three validator regimes. Target is **≥67%**. |
| Oracle pass@8 ≈ 72% gives 7pp headroom; selector picks 60/72 = 83% of available correct. |
| Next agent should focus on lifting selector pick-rate (or oracle@8 ceiling), not validators. |
