Abstract

fetched live from OpenAlex

Intermittent photic stimulation (IPS) is an activating procedure meant to elicit or accentuate epileptiform discharges during an EEG. There is insufficient clinical data to advocate IPS in the routine EEGs of all adult patients. We therefore sought to address the clinical significance of routine IPS in the adult population. We retrospectively reviewed 100 consecutive abnormal EEGs in adult patients (inpatients and outpatients) who had undergone photic stimulation in our laboratory. Nine patients had abnormalities noted during IPS. The abnormalities consisted of sharp waves in four patients and focal slowing in five patients. Only one patient had abnormalities on IPS that provided information additional to that seen on the baseline record.

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. 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.
