FedCMAPSS: A Benchmark for Federated Learning in Remaining Useful Life Estimation

Read the original on arXiv Machine Learning →

FedCMAPSS is a new benchmark for federated learning applied to remaining useful life (RUL) estimation, built on the NASA C‑MAPSS dataset. It defines five standardized tasks that mimic real‑world industrial scenarios, from ideal IID conditions to highly heterogeneous data distributions. The paper evaluates state‑of‑the‑art federated optimization algorithms across multiple neural architectures, providing reproducible baselines and publicly available code and data splits.

Data-Driven Maintenance Optimization: Aligning Prognostic Learning with Decision Objective

The paper investigates data‑driven predictive maintenance where health‑condition estimation is coupled with an ordering‑replacement decision model. It shows that the traditional Estimate‑Then‑Optimize (ETO) approach can lead to inconsistent, suboptimal decisions and introduces an Integrated Estimate‑Optimize (IEO) framework that directly optimizes maintenance cost, bypassing conventional accuracy metrics. Experiments on CMAPSS data demonstrate that IEO reduces mean maintenance cost by 14.8–22.7% versus ETO and 7.2–11.8% versus a decision‑oriented baseline, while also lowering failure rates and cost variability, even when prediction errors are higher.
