Abstract

fetched live from OpenAlex

The notion of the state of health is widely used in asset management. For instance, electric vehicle batteries are replaced after they lose ∼30% capacity, which means that their state of health is not good enough for reliable use in day-to-day travels, even though they still possess 70% capacity. Estimating the state of health of an asset is difficult, and for a power grid spanning thousands of kilometers and interconnecting millions of components, it is barely imaginable. We use familiar biomedical tests, such as blood tests, to grasp quantitative information about the health of a person, which is then interpreted by a doctor. A similar measurement-based approach is adopted in power grid operations. Electronic devices located in substations acquire and process current and voltage signals, breaker status, meteorological data, etc., which are sent to control rooms for digestion and interpretation by power system operators.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
