Abstract

fetched live from OpenAlex

A system with a complex data structure which provides for diagnosis of multiple disorders of the heart is introduced. In the proposed data structure, a tree is used to represent a waveform. The normal and abnormal electrocardiogram (ECG) waveforms are represented by a tree structure. The degree of mismatch between the two trees in terms of node splitting and merging operations are calculated. The three distances which are a measure of the structural deformation of the waveforms form the background medical information required for diagnosis. A key characteristic of the system is the congenial man-machine interface. The system is capable of explaining to the user the reasoning process for its diagnosis. The model is independent, thereby allowing expansions to include disorders from other disciplines.>

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.
