Abstract

fetched live from OpenAlex

Epileptic seizures may be described as the population entrainment of low complexity activities. Multistage seizure detection implemented using hidden Markov model (HMM) was proposed for the analysis of intracranial EEG recordings of epilepsy patients. The number of hidden states and the number of Gaussian clusters of the HMM were obtained using an unsupervised method. Multiple dynamic stages had been found leading to ictal activity. High sensitivity and specificity can be achieved based on receiver operating characteristic curve analysis (with area > 0.85). Spatial generalisation features study suggested that HMM framework is independent of the subject and the testing recording location.

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.
