Device Maintenance Prediction
Predictive maintenance AI: SparkNet + Random Forest models analyze equipment aging trends and predict next maintenance windows. Feature engineering on intervals, fault frequency, and usage intensity with multi-model comparison.
Predictive maintenance recommendations replacing fixed-cycle scheduling, reusable model pipeline
Problem
Equipment maintenance is typically reactive or fixed-cycle, leading to either premature servicing or unexpected failures.
Solution
ML pipeline: historical maintenance data → feature engineering (intervals, fault frequency, usage intensity) → SparkNet + Random Forest prediction → maintenance window recommendations with risk-priority scoring.
Key Highlights
- ▸Designed predictive maintenance workflow from historical service records
- ▸Implemented SparkNet + Random Forest for next-maintenance timing prediction
- ▸Built feature engineering pipeline for intervals, fault frequency, and usage intensity
- ▸Multi-model comparison with regression and time-series baselines

What I Learned
Feature engineering on maintenance intervals and usage patterns is more impactful than complex models; ensemble approaches provide more stable predictions than single models.
