Abstract

fetched live from OpenAlex

Abstract This paper proposes a systematic method of estimating the mean life of an aged power equipment group based on the approach of Dr. W. Li of BCTC, Canada (IEEE Transactions on Power Systems, February 2004). In order to estimate the mean life of aged power equipment systematically and effectively with the operation data sequence, a linear estimation method is developed on the assumption that the stochastic behavior of aged equipment life determines the probability distribution model, such as the normal model or the Weibull model. Introductory and practical examples are illustrated for verification of the proposed approach. © 2009 Wiley Periodicals, Inc.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
