Andreas Pierratos Tribute: Personal Reflections
Bibliographic record
Abstract
Since the passing of Andreas Pierratos on November 15, 2022, we have had many occasions to reflect on what our relationship with a friend and colleague has meant. We have done this in solitude, with colleagues while at work and more recently, in a tribute organized at Humber River Hospital on March 26, 2023. We also had the opportunity to expand, in the February 2023 issue of the Nephrology News & Issues, on his many contributions to nephrology and to the betterment of patients’ lives. For this collaboration, we thought we would share our personal reflections of this unique individual, with the hope that this effort would provide a deeper appreciation of his unique humanity.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
