Abstract

fetched live from OpenAlex

Data obtained from destructive one-shot devices are usually studied through a binary response variable indicating failure or success of the device. But, in many practical situations, it may be more realistic to consider that the failure of the device may be due to several competing risks. In this paper, we develop divergence-based inference for one-shot device testing under Weibull lifetimes. This inference is shown to be more robust than the classical MLE-based inference, without a significant loss in efficiency when the data arise from the true model. A detailed simulation study is done to show the behaviour of the proposed estimation method and the associated inference. Finally, the developed methods are applied to a motor insulation dataset for illustrative purposes.

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.
