Abstract

fetched live from OpenAlex

This paper examines the results of two initial studies of the problemsolving strategies used by more and less skilled medical professionals during mammogram interpretation.The first study examined the cognitive processing of staff radiologists and radiology residents, while the second looked at surgical residents and medical students as they individually solved a set of breast disease cases.Analyses of 100 verbal protocols from the two studies resulted in the development of a problem-solving model of mammogram interpretation and a characterization of novice expert differences based on performance measures.Results revealed that with increasing levels of expertise there were significant increases in the number of radiological observations and findings, proportion of correct diagnoses, use of data-driven problem solving, and diagnostic planning.The analysis provides a valuable initial characterization of mammogram interpretation across a broad range of expertise levels with implications for the design of computerbased learning environments aimed to train medical professionals to interpret mammograms.

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 distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
