SARNet: A Spike-Aware consecutive validation Framework for Accurate Remaining Useful Life Prediction
This work improves system reliability and reduces maintenance risk for engineers by providing a more robust and interpretable RUL prediction method, though it is incremental as it builds on existing temporal convolutional networks.
The paper tackled the problem of accurately predicting remaining useful life (RUL) by addressing fragility around fault onset and lack of interpretability in existing models, achieving lower error rates with RMSE 0.0365 and MAE 0.0204 compared to baselines.
Accurate prediction of remaining useful life (RUL) is essential to enhance system reliability and reduce maintenance risk. Yet many strong contemporary models are fragile around fault onset and opaque to engineers: short, high-energy spikes are smoothed away or misread, fixed thresholds blunt sensitivity, and physics-based explanations are scarce. To remedy this, we introduce SARNet (Spike-Aware Consecutive Validation Framework), which builds on a Modern Temporal Convolutional Network (ModernTCN) and adds spike-aware detection to provide physics-informed interpretability. ModernTCN forecasts degradation-sensitive indicators; an adaptive consecutive threshold validates true spikes while suppressing noise. Failure-prone segments then receive targeted feature engineering (spectral slopes, statistical derivatives, energy ratios), and the final RUL is produced by a stacked RF--LGBM regressor. Across benchmark-ported datasets under an event-triggered protocol, SARNet consistently lowers error compared to recent baselines (RMSE 0.0365, MAE 0.0204) while remaining lightweight, robust, and easy to deploy.
