Open Media Classes at Coventry University: Final Evaluation Report 2015
Bibliographic record
Abstract
This report offers a reflection on findings from a one year evaluation study into the distributed open media classes at Coventry University \n \nThe study team comprised Lou McGill and Tim Gray of \nLou McGill Consultancy Ltd. This report is augmented by \nan open wiki (bit.ly/1KqL4nH) which includes more detail \nabout the approaches used during the study and findings \nare also presented as a series of web pages \n(comc.loumcgill.co.uk). We would like to thank the \nDepartment of Media in the School of Art and Design for \ntheir input, openness and patience during the study. \n \n
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.

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.
