CNN-based classifier for subject-independent MBTI Extraversion/Introversion preference classification from short-time EEG signals

Read the original on arXiv Machine Learning →

The paper investigates whether brief, minimally processed EEG segments can differentiate individuals labeled as extraverted or introverted by the Myers–Briggs Type Indicator. Using a subject‑independent nested 5‑fold cross‑validation, the authors compared EEGNet, EEGProgress, and a new compact convolutional network called SSCNet. SSCNet achieved the highest mean accuracy (0.6481), AUC (0.7063), and F1‑score (0.6276), exhibited the lowest variability across folds, and proved computationally efficient with the shortest training epoch time and highest throughput.

BRIDGE-EEG: Bridging Self-Supervised Pretraining and Efficient Deployment for Cross-Dataset EEG Classification

BRIDGE-EEG is an efficient multi‑task EEG classification pipeline that leverages self‑supervised pretraining while dramatically reducing model size. It maps heterogeneous EEG recordings to a unified 62‑channel time‑frequency representation, pretrains an SE‑ResNet18 teacher with SimCLR, and distills it into smaller SE‑ResNet8 and SE‑ResNet4 students. The compact models achieve accuracy comparable to or better than larger foundation models on abnormality detection and emotion recognition, and they consume up to three times less energy on edge devices, enabling deployment on wearable hardware.
