waleed habib completed Predictive Maintenance: Industrial ML for Fault Detection

Built an end-to-end rolling-bearing fault detector from vibration data: visualized the signal, engineered RMS/kurtosis/crest-factor and envelope-spectrum features, localized the fault to BPFO, and trained a shallow decision tree within an embedded budget. Evaluated on held-out bearings with reported catch-rate and false-alarm rate, then defended a 0.42 alarm threshold using explicit downtime-vs-inspection cost reasoning.
