Contrastive Siamese Representation Learning for Predictive Maintenance of Electrical Submersible Pumps

The paper introduces a fault‑diagnosis framework for electrical submersible pumps that uses Siamese contrastive representation learning to handle class imbalance and a prior‑corrected k‑nearest neighbor classifier for robust fault classification. It extracts discriminative vibration‑domain features, trains a Siamese network to cluster same‑fault samples, and applies a distance‑weighted KNN to mitigate imbalance. Validation with a Leave‑One‑ESP‑Out strategy shows consistent performance across unseen pump units, indicating potential for reliable predictive maintenance in offshore oil production.

Robust Prototypical Networks for Few-Shot Sensor Fault Diagnosis

The paper introduces Multi-Episode Prototypical Networks (MEPN), a variant of prototypical networks that aggregates class prototypes from multiple disjoint support episodes to reduce prototype variance in few-shot sensor fault diagnosis. MEPN is evaluated on the DeFACTO sensor dataset with synthetic fault injections, achieving significantly higher one-shot accuracy than single-episode baselines while matching ProtoNet performance under a 10-sample support budget. The approach demonstrates that prototype accumulation improves stability without altering the encoder architecture.

Trust-Aware Predictive Emissions Monitoring for Gas Turbine Fleets with Limited Labelled Data

arXiv:2606. 06156v1 Announce Type: new Abstract: Machine learning-based predictive emissions monitoring systems offer a practical alternative to direct emissions measurement, but their deployment across gas turbine fleets is challenging when emissions labels are available for only a small subset of assets.

Learning to Predict, Discover, and Reason in High-Dimensional Event Sequences

The paper proposes a new framework for automated fault diagnostics in modern vehicles by treating diagnostic trouble codes (DTCs) as a high‑dimensional language. It introduces Transformer‑based models for predictive maintenance, scalable causal discovery methods, and a multi‑agent system that automatically generates Boolean error‑pattern rules. The approach aims to replace costly manual grouping of DTCs with scalable, data‑driven techniques.
