SRDC Working Paper Series 06-04 Evaluating Search and Matching Models Using Experimental Data The Self-Sufficiency Project
Bibliographic record
Abstract
analysis for the Self-Sufficiency Project (SSP) sponsored by Human Resources and Skills Development Canada (HRSDC). The Self-Sufficiency Project is sponsored by HRSDC. This paper was produced for the Social Research and Demonstration Corporation (SRDC). The opinions expressed herein are the authors ’ and do not necessarily reflect those of SRDC or HRSDC. The Social Research and Demonstration Corporation is a non-profit organization and registered charity with offices in Ottawa, Vancouver, and Sydney, Nova Scotia. SRDC was created specifically to develop, field test, and rigorously evaluate social programs. SRDC’s two-part mission is to help policy-makers and practitioners identify social policies and programs that improve the well-being of all Canadians, with a special concern for the effects on the disadvantaged, and to raise the standards of evidence that are used in assessing social policies and programs. As an intermediary organization, SRDC attempts to bridge the worlds of academic researchers, government policy-makers, and on-the-ground program operators. Providing a vehicle for the development and management of complex demonstration projects, SRDC seeks to work in close partnership with provinces, the federal government, local programs, and private philanthropies.

How this classification was reachedexpand
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.
