Towards Unified and Data-Efficient Prognostics and Health Management with Tabular Foundation Models
Summary
A new framework applies Tabular Foundation Models (TFMs) to industrial time series for Prognostics and Health Management (PHM), addressing challenges like fragmented and poorly labeled data. Unlike most time-series foundation models designed for forecasting long, coherent sequences, this approach converts raw unit-level signals into tabular rows. Evaluated against sequence models, transformer baselines, and gradient-boosted trees, TFMs achieved the best average ranks across prognostic and diagnostic tasks. Key findings indicate that PFN-based models are competitive in low-data regimes, temporal context can be preserved in tabular representations, and performance relies on representative context construction under subsampling. This demonstrates TFMs offer a practical, general interface for heterogeneous PHM problems.
Key takeaway
For Machine Learning Engineers developing PHM solutions, this research suggests you should consider Tabular Foundation Models. They provide a data-efficient and unified approach for both prognostic and diagnostic tasks, even with fragmented industrial data. You can leverage in-context learning by converting time-series signals into tabular formats, potentially outperforming traditional sequence models. Focus on constructing representative contexts during data subsampling to optimize performance.
