Abstract

fetched live from OpenAlex

Magneto-optic/eddy current imaging (MOI) is becoming widely used for aging aircraft inspection for cracks and corrosion. However, many test parameters affect the accept/reject decision about a test sample and hence the overall performance of MOI system. The optimization of the parameters is extremely crucial in enhancing the performance of MOI system. This article uses the Taguchi method to change parameter values simultaneously to search for the optimum set of test parameters for maximizing system performance for a given sample geometry and critical crack. It is also important at the same time the system performance be unaffected by variations in parameters. Efficiency of Taguchi's partial factorial design is obvious. The optimum set of parameters is found by means of analyses of main effects. Analysis of variance identifies those parameters that need to be controlled carefully. A response-model approach is utilized as a complement to the Taguchi method.

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.
