Bibliographic record
Abstract
An increasing number of people are living outside their country of birth. In 2019, the number of international migrants worldwide reached 272 million, up from 221 million in 2010 (United Nations, 2019a). People migrate for many reasons, including to search for jobs or education or to make a better future for themselves and their families. At the same time, political conflict, poverty, inequality and a lack of sustainable livelihoods continue to compel many people to leave their homes and undertake dangerous and sometimes fatal journeys. Indeed, some 32,000 deaths among migrants in transit were recorded by the Missing Migrants Project between 2014 and 2018 (IOM, 2019a); and between 2010 and 2017, the global number of refugees and asylum seekers increased by about 13 million, accounting for close to a quarter of the total increase in the number of international migrants (UNHCR, 2019a; UNRWA, 2019).

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
