| # PINNBench |
|
|
| A controlled benchmark for evaluating training-policy selection in hybrid Physics-Informed Neural Network (PINN) and neural-operator solvers. PINNBench accompanies the paper *"PINNBench: A Benchmark and Evaluation Study of Training Policy Selection in Hybrid PINN-Operator Solvers"* (anonymous submission, NeurIPS 2026 Evaluations and Datasets Track). |
|
|
| ## What is in this repository |
|
|
| This Hugging Face dataset hosts the **benchmark protocol artifacts** + **logged results** of 1,539 controlled training runs on 13 PDE configurations spanning 8 equation families. The dataset is **not raw simulation data** (PDE reference solutions are analytical and regenerated at runtime); it is the **decision-relevant evaluation record** that supports the paper's headline claims. |

|
| ## How to load |
|
|
| The recommended access pattern is direct JSON read; result schemas are documented in `MANIFEST.md`. |
|
|
| ```python |
| from huggingface_hub import hf_hub_download |
| import json |
| |
| routing_path = hf_hub_download( |
| "PINNBench/pinnbench", |
| "results_paper_combined/routing_evaluation/results.json", |
| repo_type="dataset", |
| ) |
| with open(routing_path) as f: |
| routing = json.load(f) |
| ``` |
|
|
| `datasets`-library config aliases (`routing_evaluation`, `stage_ablation`, `meta_router`, `regret_bound_validation`, `adaptive_epsilon`, `external_probes`) are declared in the YAML header above for convenience. |
|
|
| ## Verification |
|
|
| Every headline claim in the paper is recomputed from these JSONs by the script `scripts/verify_claims.py` in the source repository. Reproduced PASS results: |
|
|
| | Claim | Source artifact | Computed | Paper | |
| |---|---|---|---| |
| | Total runs | union | 1,510 enumerable + 29 probes | 1,539 | |
| | Nested PDE-aware routing accuracy | `meta_router/results.json` | 84.62% (11/13) | 84.6% | |
| | Full RF+PDE routing | `meta_router/results.json` | 61.54% (8/13) | 61.5% | |
| | Stage-2 compute savings | analytical | 60.0% (K=3, Eₚ=50, E₂=500) | 60% | |
| | Diagnostic regret bound | `regret_bound_validation.json` | 33/52 overall, 33/39 if k∈{10,50,100} | 33/52, 33/39 | |
| | Accuracy–regret dissociation | `routing_evaluation/results.json` | 77.27× (0.0850 / 0.0011) | 77× | |
| | Family-macro accuracy (LOPO-F) | `routing_evaluation/results.json` | 81.2% physics-loss-final (6/8) | 81.2% | |
| | KdV1D causal effect (PDE residual) | `rq1e_kdv_10seed_causal/results.json` | 0.0096 / 0.0105 | 0.010 / 0.011 | |
| | Adaptive-ε mitigation (AdvDiff1D) | `adaptive_epsilon/results.json` | 0.78 → 0.98 | 0.78 → 0.97 | |
|
|
| ## Reproducibility caveats |
|
|
| - All training results were computed at the **final epoch** of each stage (no best-checkpoint selection, no validation set). |
| - Evaluation points were regenerated per seed via `torch.rand` rather than loaded from a fixed grid; per-seed metric variance therefore includes evaluation-point sampling variance. |
| - The `rq1e_kdv_10seed_causal/results.json` summary aggregate has a `nan-mean` bug for some fields; per-seed means are recomputed by the verification script. |
