Abstract
ABSTRACT The Imperial College of Science and Technology, a constituent college of the University of London in the 1960s, had the good fortune to be one of the first colleges in the United Kingdom to have access to digital computing facilities. This review traces the history of the application of computing in the Geochemical Prospecting Research Centre and its successor, the Applied Geochemistry Research Group, as computing moved from being a frontier research area to becoming a commonplace tool. The three principal areas in which it was involved comprised: the quality control, and thereby assurance, of analytical data; the production of pioneering atlases of regional geochemical variation in Northern Ireland (1973) and England and Wales (1978); and the application of methods introduced by workers in pattern-recognition and statistics to the interpretation of land-based and marine regional geochemical data.
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.
