Strategies to face imbalanced and unlabelled data in PHM applications.

, 2013
International audienceAccuracy and usefulness of learned data-driven PHM models are closely related to availability and representativeness of data. Notably, two particular problems can be pointed out.

Modifiable Areal Unit Problem on Network Topological Measures for Public Transit Flows

Transactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT Transit flows can provide useful insights into urban mobility patterns and dynamics. Generally, the transit flows between the origin and destination locations are aggregated into areal units for statistical analysis. A well‐known issue is the modifiable areal unit problem (MAUP), where its sensitivity depends on the basic areal units.

TOWARDS DEVELOPING A NOVEL FRAMEWORK FOR PRACTICAL PHM: A SEQUENTIAL DECISION PROBLEM SOLVED BY REINFORCEMENT LEARNING AND ARTIFICIAL NEURAL NETWORKS

International Journal of Prognostics and Health Management, 2019
The heart of prognostics and health management (PHM) is to predict the equipment degradation evolution and, thus, its Remaining Useful Life (RUL). These predictions drive the decisions on the equipment Operation and Maintenance (O&M), and these in turn ...

ETHICS IN PROGNOSTICS AND HEALTH MANAGEMENT

International Journal of Prognostics and Health Management, 2019
As we enter an era where intelligent systems are omnipresent and where they also permeate Prognostics and Health Management ( PHM ), the discussion of moral machines or ethics in engineering will inevitably engulf PHM as well.

Prognostic-oriented Fuel Cell Catalyst Aging Modeling and Its Application to Health-Monitoring and Prognostics of a PEM Fuel Cell

International Journal of Prognostics and Health Management, 2014
Today, poor long-term performance and durability combined with high production and maintenance costs remain the main obstacles for the commercialization of the polymer electrolyte membrane (PEM) fuel cells (PEMFCs).
