HD-BasinFlow Experiment Suite

This repository implements the validation plan in hd_basinflow_experiment_instructions.pdf.

The suite includes:

• A runnable HD-BasinFlow optimizer for objectives on [0, 1]^d.
• Exact synthetic gradients and local weighted ridge gradient estimation support.
• Active-subspace estimation, kNN flow graph construction, basin certificates, repair sampling, and ablations.
• Synthetic benchmarks and baseline comparisons.
• Required CSV logs, processed metrics, plots, and reports/experiment_report.md.
• A real-data status probe for the Hugging Face datasets named in the plan. Real ML runs are not silently faked.
• A target-savings benchmark mode for the commercial claim: comparable validation quality with less compute.

Commercial Validation Path

The narrow commercial claim is:

HD-BasinFlow can reach comparable validation quality on selected HPO/fine-tuning workloads while using less compute than common search baselines.

The current pass/fail rule is intentionally conservative:

• Compare against Random Search, Sobol/quasi-random, Optuna TPE, and ASHA/Successive Halving.
• Treat HD-BasinFlow as passing a comparison only when median final loss is within 1% of the baseline median final loss.
• Require the target-savings policy to reach that quality with at least 20% fewer evaluations.
• Treat 15-30% savings as the first commercial operating band.
• Report failures and underpowered rows instead of hiding them.

Build the target-savings report from the latest combined raw evaluations:

python3 scripts/build_target_savings_report.py \
  --input runs/combined_report/raw/evaluations.csv \
  --outdir runs/target_savings_benchmark

That produces:

• target_savings_decisions.csv: per-dataset/per-baseline pass-fail table.
• target_savings_summary.csv: aggregate competitor comparison.
• target_savings_report.md: technical report.
• target_savings_operating_point.pdf: plot for the report/deck.
• customer_deck_outline.md: short commercial deck outline.
• demo_target_savings.py: minimal demo command that prints decisions.

Run a clean A100 commercial benchmark suite:

bash scripts/run_commercial_benchmark.sh runs/commercial_benchmark_a100

This stages repeated image, transformer, classic NLP, and tabular workloads on Fashion-MNIST, CIFAR-10, SST-2, IMDB, AG News, and tabular credit. The script then aggregates results and rebuilds the target-savings report.

Run the stronger 20-seed internal validation gate with GPU telemetry:

bash scripts/run_stronger_commercial_benchmark.sh runs/commercial_benchmark_a100_20seed

That writes gpu_telemetry.csv, run.log, per-workload outputs, a combined report, and a fresh target-savings package. Use this before making external sales claims.

The latest combined report in this workspace uses synthetic_fair_20x80, dimension_scaling_extended, sobol_dimension_scaling_3x32, real_classic_curves_20x8, tabular_credit_extra_80x8, transformer_curves_20x4, and image_gpu_larger_5x12, plus fashion_full_1x12, cifar_full_1x12, ag_news_full_1x12, tabular_credit_full_1x12, sst2_full_1x8, and imdb_larger_1x8, plus imdb_full_1x8. It contains 152,928 evaluation rows, 30 experiments, 133 PNG figures, 133 PDF figures, 20 fair-seed runs for every synthetic method/ablation group including Sobol/quasi-random, 20 seeds for AG News/Fashion-MNIST/CIFAR-10 plus 5 larger GPU-backed Fashion-MNIST/CIFAR-10 seeds at 1024/512 train/validation samples and 2 epochs, 100 seeds for tabular credit, 20 seeds for SST-2/IMDB DistilBERT, one full-scale Fashion-MNIST seed at 50,000/10,000 train/validation samples and 2 epochs, one full-scale CIFAR-10 seed at 40,000/10,000 train/validation samples and 2 epochs, one full-size AG News seed at 100,000/20,000 train/validation examples, one full-available tabular credit seed at 13,000/3,714 train/validation examples, one full SST-2 DistilBERT seed at 67,349/872 train/validation examples, one larger IMDB DistilBERT seed at 25,000/2,000 train/validation examples, one full-validation IMDB DistilBERT seed at 25,000/25,000 train/validation examples, and 3 seeds for each dimension-scaling method group including the Sobol/quasi-random supplement. The real_classic_curves_20x8 and transformer_curves_20x4 rows have verified nonempty train curves, validation curves, and final validation metrics; image_gpu_larger_5x12 adds the larger image-workload supplement on an A100 GPU, and fashion_full_1x12 and cifar_full_1x12 add full-scale image A100 supplements. The ag_news_full_1x12 folder adds the full-size AG News CPU sklearn supplement. The tabular_credit_full_1x12 folder adds the full-available tabular CPU sklearn supplement. The sst2_full_1x8 folder adds the full SST-2 DistilBERT A100 supplement. The imdb_larger_1x8 folder adds the larger IMDB DistilBERT A100 supplement. The imdb_full_1x8 folder adds the full-validation IMDB DistilBERT A100 supplement. The synthetic_fair_20x80 folder replaces the older synthetic ablation source in the combined report and shows at least one ablation worse than full on all six synthetic ablation tasks, while still reporting the tasks where an ablation beats full.

The allocation_synthetic_20x80 supplement contains 19,200 evaluation rows with explicit HD-BasinFlow allocation_decision, killed_early, and kill_reason fields. Its plot_data/early_stopping_kill_metrics.csv reports kill precision, kill recall, and good-run false-kill rate for both HD-BasinFlow and ASHA across the six synthetic tasks. Reports also write plot_data/false_kill_threshold_summary.csv and figures/false_kill_threshold_summary.png / .pdf, which classify rows against the PDF's 5-10 percent good-run false-kill condition.

The real_classic_allocation_smoke and transformer_allocation_smoke folders verify the same allocation/kill logging schema on all six real workload families. At these small budgets HD-BasinFlow initializes and explores globally, while ASHA contributes real-task kill decisions; larger real budgets are needed to exercise HD-BasinFlow basin continuation and repair spawning on the real workloads. The ag_news_allocation_basin_smoke folder adds a larger real AG News run that exercises HD-BasinFlow explore_edge_flow allocation.

The subspace_dimension_scaling_3x32 supplement contains 5,184 evaluation rows, including 1,728 HD-BasinFlow rows with true Frobenius subspace_error=||UU^T-UhatUhat^T||_F against the known rotated-active subspace. Its plot_data/active_subspace_recovery.csv and plot_data/dimension_scaling_summary.csv include the subspace-error fields.

Deliverables

Each run writes:

• raw/evaluations.csv
• processed/metrics.csv
• processed/real_data_status.csv when requested
• figures/*.png and figures/*.pdf
• plot_data/*.csv
• reports/experiment_report.md

Reports include plot_data/gpu_time_savings.csv and figures/gpu_time_savings.png, a wall-clock time-to-target proxy for the GPU-time savings requirement.

Reports include both plot_data/best_loss_vs_evaluations.csv and plot_data/best_loss_vs_walltime.csv, with per-experiment PNG figures for both views.

HD-BasinFlow ablation reports include both figures/ablation_best_loss_*.png / .pdf and figures/ablation_time_to_target_*.png / .pdf. They also write plot_data/ablation_interpretation.csv, which states whether full or an ablation wins by median final loss and whether ablated pieces appear to matter.

Reports with HD-BasinFlow allocation decisions include plot_data/basin_allocation_summary.csv and figures/basin_allocation_summary.png, which summarize the mix of initialization, global exploration, edge-flow, basin continuation, and repair sampling.

Reports also write plot_data/basin_allocation_over_time.csv; when allocation decisions are present, they include figures/basin_allocation_over_time.png.

Reports with ML curve logs include plot_data/validation_curves.csv and figures/validation_curves.png.

Reports with matching noisy_* and clean synthetic experiments include plot_data/noise_robustness.csv, figures/noise_robustness.png, and figures/noise_robustness.pdf, comparing median final loss and IQR shifts under observation noise.

Reports generated from known active-subspace synthetic objectives include subspace_error in raw/evaluations.csv, plot_data/active_subspace_recovery.csv, figures/active_subspace_recovery.png / .pdf, and plot_data/dimension_scaling_summary.csv.

Generated reports include an HD-BasinFlow Compute Savings Verdict section an explicit False-Kill Threshold Check, an Ablation Interpretation section, and a What Failed Or Remains Unproven section, so losses and missing success criteria are stated explicitly instead of inferred from tables.

HD-BasinFlow evaluation rows now populate allocation_decision, killed_early, and kill_reason for basin continuation, repair spawning, and certificate-rejected allocation decisions.

Real ML evaluation rows now populate train_curve_json, val_curve_json, and final_test_metric from observed model training/evaluation values when those workloads are rerun. Existing historical run folders keep the values produced by the code version that generated them.
