Suggested use cases

• Remaining Useful Life (RUL) regression — remaining_useful_life.csv provides per-timestamp RUL targets in hours/days plus 5-class RUL buckets (<7d / 7–30d / 30–90d / 90d–1y / >1y). 45,000 timestamps × 250 assets is right-sized for LSTM, transformer, and gradient-boosting prognostics baselines.
• Fault-signature classification from FFT — 4-band FFT spectra (1x, 2x, bearing, cavitation) × fault_signature labels enables direct bearing-fault, cavitation, and misalignment classification training.
• 7-day + 30-day failure probability — predictive_labels.csv carries both horizons calibrated via sigmoid on degradation index. Useful for early-warning vs. medium-term planning model comparisons.
• Multi-modal degradation modeling — 6 telemetry modalities are per-timestamp aligned per asset (vibration + FFT + thermal + lubrication + pressure + acoustic), enabling true multi-modal fusion research.
• Maintenance-reset event detection — degradation trajectories include stochastic "reset points" simulating maintenance interventions; useful for change-point detection and survival analysis with competing-risks models.
• PHM Society challenge-style benchmarking — pre-built target labels (target_failure_mode + target_root_cause) follow PHM Society conventions for end-to-end prognostics evaluation.
• Maintenance strategy ROI quantification — 4 strategies (preventive / condition_based / run_to_failure / reliability_centered) × workorder & downtime tables enable strategy-vs-availability ROI modeling.

Or with pandas directly:

import pandas as pd
from huggingface_hub import hf_hub_download

path = hf_hub_download(
    repo_id="xpertsystems/oil039-sample",

Calibration notes & limitations

In the spirit of honest synthetic data, a few things buyers of the sample should know:

1. Aggressive 90-day degradation simulation. The sample window compresses a full degradation trajectory into 90 days for ML utility, so the severity_band distribution is skewed toward warning/critical/failure (≈ 70% combined), with only ~2% of timestamps in normal. This is intentional — it provides positive-class density for failure classifiers and RUL regressors. For studies that require steady-state healthy operations, filter to degradation_score < 0.30 or use the early window (first 14 days). The full product simulates 730 days with slower drift and recovers a healthy normal-band majority.

2. Vibration RMS units differ from OIL-038. Mean vibration RMS in this dataset is ~0.39 (different unit normalization than OIL-038's ~7.14 in mm/s ISO 10816 units). Crest factor (mean 4.92) and kurtosis (mean 7.1) are validated against ISO 13373-1 / ISO 17359 instead, since they're dimensionless and directly comparable across calibrations. For absolute ISO 10816 vibration severity classification, use OIL-038.

3. FFT fault_signature label sparsity. The fault_signature column in fft_spectra.csv is 99.6% "none" in the sample. The label is set only when the band-specific multiplier exceeds a degradation-dependent threshold, which is rare in the sample window. For ML use, derive your own threshold from harmonic_amplitude × spectral_energy on the matched-fault-mode band, or use the full product's 7-band decomposition which exposes 3 additional fault signatures.

4. Lubrication water-ppm trajectory. Median water ppm is ~375 across the sample (above ISO 4406 clean threshold of 200) because the generator's water content formula 80 + 600 × degradation puts most degraded assets above the clean threshold. This is consistent with the aggressive degradation simulation (point 1). For "healthy lubrication" baselining, filter to contamination_level < 0.2.

5. Per-timestamp RUL skew. The RUL bucket distribution at sample scale is heavily weighted toward 30-90d and 90d-1y (≈83% combined) with only ~17% in the <7d and 7-30d buckets that ML teams care about most for early warning. For balanced training, oversample on rul_bucket ∈ {<7d, 7-30d} or use the full product (730-day window exposes more imminent-failure windows per asset).

6. Workorder + failure event counts. Sample mode produces ~110 workorders and ~55 failure events. These are sparse on purpose (modeling realistic event rates over 90 days at 250 assets) but limit small-sample statistics on severity/severity-pyramid metrics — the scorecard's M05 (IOGP major share) tolerance is intentionally widened to ±0.15 for this reason. The full product recovers tight pyramid ratios at production scale.

7. Deterministic seeding. All 13 tables are deterministic on --seed. Catalog default is seed 42. Seed sweep verifies Grade A+ across {42, 7, 123, 2024, 99, 1}.
