Abstract

fetched live from OpenAlex

This paper investigates a data-driven approach to the detection of statistically reliable fluctuations in electroencephalographic (EEG) brain waves. The main advantage of this approach is the ability to automatically identify meaningful sources of variation in signals dominated by large spatiotemporal fluctuations due to noise. The approach is tested on artificial data as well as on EEG signals obtained in a cognitive experiment. Results not only show that the approach can robustly identify meaningful variations in brain activity, but also open possible applications to brain-computer interfaces based on single-trial analyses.

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.
