Abstract

fetched live from OpenAlex

Penalized functional regression is a useful tool to estimate models for applications where the effect/coefficient function is assumed to be truncated. The truncated coefficient function occurs when the functional predictor does not influence the response after a certain cutoff point on the time domain. The R package PFLR offers an extensive suite of methods for advanced functional regression techniques with penalization. The package implements four distinct methods, each tailored to different models, effectively addressing a range of scenarios. This is demonstrated through simulations as well as an application to particulate matter emissions data. Generic S3 methods are also implemented for each model to help with summary, visualization and interpretation.

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.
