Abstract

fetched live from OpenAlex

Self-consistent algorithms for modelling the cause-specific cumulative incidence functions in an interval censored, competing risks context were proposed by Hudgens et al. (2001) and Adamic (2006). One of the drawbacks of these methods was that convergence was only achieved over a small class of points, called cause-specific innermost intervals. Braun et al. (2005) proposed a self-consistent kernel modification to Turnbull's univariate algorithm as a way to fill in the gaps between the resulting innermost intervals. We generalize this approach to the plateau of interval censored and masked competing risks. The new approach is illustrated by applying the method to a human trypanosomiasis data set.

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.
