Abstract

fetched live from OpenAlex

Digital EEG systems allow for the creation of specialized montages not commonly available previously with analog equipment. Montages that employ the principles of local average reference techniques utilize a subset of spatially separated electrodes to produce a synthetic reference that will aid in localization. By employing these techniques, focal discharges can be visually enhanced and properly localized. The Laplacian transform is an example of a local average reference and the principles and construction of this montage are described here in brief detail. Though the montage is not suited for all situations, integration into existing lab protocols will enable technologists to provide alternative views when required in ambiguous and difficult to interpret recordings.

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.
