Predictive Maintenance: Industrial ML for Fault Detection

Eine ProoV-Fallstudie · Lernprojekt, kein Arbeitsverhältnis
Built a compact rolling-bearing fault detector end to end: engineered time-domain features, used envelope-spectrum energy at supplied defect frequencies to localize the fault, trained a shallow decision tree on training bearings only, and evaluated it on a held-out set with catch-rate and false-alarm metrics. The candidate also defended a 0.40 alarm threshold with explicit cost reasoning and translated the result into a clear maintenance recommendation.

Was herausstach6
- Trained a depth-capped decision tree on training bearings only and stated a small tree size (depth 1, 3 nodes) against the embedded budget.
- Reported held-out catch-rate and false-alarm rate rather than evaluating on training data.
- Wrote a maintenance memo that ties the threshold choice to concrete costs and explicitly identifies the outer race via BPFO dominance.
- Leakage-Free Model Training
- Honest Held-Out Evaluation
- Physics-Informed Fault Interpretation
