# Longitudinal ERP dataset (RSVP): EEG decoding results

RSVP face-target ERP, the same people at nominal Day 1, 7, 80 and 200 visits

A longitudinal EEG dataset of event-related potential (figshare 27201003) holds EEG from a rapid serial visual presentation task in which participants identified a target face: 15 people (Group A) recorded at four visits labelled Day 1, 7, 80 and 200, and 52 people (Group B) recorded once, with 57 EEG channels. Released by Chen Yang, Yufeng Zhang and colleagues (Beijing University of Posts and Telecommunications) under CC0 and described in Scientific Data (2025). Only Group A is used here.

| Method | Condition | Metric | Value | People |
| --- | --- | --- | --- | --- |
| Normalized ERP features + logistic/Platt (CPU baseline) | Trained at the first visit · nominal Day 7 | AUROC | 0.888 (0.864–0.911) — Targets: 1,794 of 72,000 events. AUROC ranks; it is not accuracy. | 15 |
| Normalized ERP features + logistic/Platt (CPU baseline) | Trained at the first visit · nominal Day 7 | Average precision | 0.359 | 15 |
| Normalized ERP features + logistic/Platt (CPU baseline) | Trained at the first visit · nominal Day 80 | AUROC | 0.879 (0.854–0.903) — Targets: 1,786 of 72,000 events. AUROC ranks; it is not accuracy. | 15 |
| Normalized ERP features + logistic/Platt (CPU baseline) | Trained at the first visit · nominal Day 80 | Average precision | 0.310 | 15 |
| Normalized ERP features + logistic/Platt (CPU baseline) | Trained at the first visit · nominal Day 200 | AUROC | 0.853 (0.827–0.879) — Targets: 1,793 of 72,000 events. AUROC ranks; it is not accuracy. | 15 |
| Normalized ERP features + logistic/Platt (CPU baseline) | Trained at the first visit · nominal Day 200 | Average precision | 0.240 | 15 |
| Normalized ERP features + logistic/Platt (CPU baseline) | Day 200 minus Day 7, the same people | AUROC difference | −0.035 (−0.065–−0.006) — 6 of 15 people lost 0.05 AUROC or more. Nominal visit labels: no claim that elapsed time caused it. | 15 |
