Abstract

fetched live from OpenAlex

Microwave imaging has been proposed for breast health assessment. The majority of the images of human subjects that have been previously reported focus on tumor detection capabilities. There is a need to correlate additional features of microwave images to clinical information in order to increase confidence in this approach. In this contribution, we present an initial exploration of the connection between the dielectric properties obtained from microwave images and breast density estimates that are readily available from mammography reports.

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.

Not 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.
