Abdelfattah et al. (2025) studied Mental stress (n=15). Machine learning and deep learning algorithms was evaluated on Classification of four states: baseline, stress, amusement, and meditation (F1 score 93% (RNN) and 99% (Traditional ML)). Recurrent Neural Networks achieved an F1 score of 93% for cross-subject stress classification, while traditional machine learning models achieved 99% when trained and tested on the same subjects.
