Predictive Maintenance: Industrial ML for Fault Detection
Condition-Monitoring Engineer · KI / ML · September 2026
Eine ProoV-Fallstudie · Lernprojekt, kein Arbeitsverhältnis
Built an end-to-end rolling-bearing fault detector from vibration data: visualized the faulty waveform, engineered time- and frequency-domain features, trained a shallow decision tree on training bearings only, and evaluated it on held-out bearings with catch-rate and false-alarm metrics. The work also localized the fault to the outer race via BPFO and defended an alarm threshold with a maintenance-focused memo grounded in the candidate’s own results.

Was herausstach6
- Used the provided envelope spectrum helper and correctly found BPFO as the dominant defect frequency, then mapped it to the outer race.
- Kept the classifier compact and interpretable, stating a depth-1 tree with 3 nodes and confirming training-only fitting.
- Reported held-out catch-rate and false-alarm rate rather than relying on training performance.
- Included a maintenance memo that connects the threshold choice to concrete operating numbers and a plain-language manager sentence.
- Leakage-Free Feature Engineering
- Honest Held-Out Evaluation
