Abstract

fetched live from OpenAlex

.In this work, for depicting the relationship between a bounded scalar response and predictors including both scalars and functions, we develop a functional partially linear single-index model based on beta distribution, which can capture the bounded feature of the response well and also provides more flexibility. Approximating the unknown functions based on B-spline simultaneously, the parametric estimates of the proposed model are obtained. Under some conditions, the asymptotic properties of the resulting estimators, including the consistency and asymptotic normality, are derived. In addition, the finite sample performance of our method is validated through some simulation studies. Meantime, real data from the Alzheimer’s disease neuroimaging initiative (ADNI) study is investigated, and the results show that our proposed model outperforms competitors.

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.
