{"pk":49447,"title":"Self-supervised EEG Representation Learning based on Temporal Prediction and Spatial Reconstruction for Emotion Recognition","subtitle":null,"abstract":"Affective Brain-Computer Interfaces has achieved remarkable advancements, enabling researchers to interpret labeled EEG data accurately. However, the annotation of EEG data is time-consuming and requires substantial effort, which limits the application in practical scenarios. In this paper, we propose a self-supervised EEG representation learning framework based on temporal prediction and spatial reconstruction (EEG-TPSR) to learn EEG representations from a large amount of unlabeled data. Our model consists of two stages: 1) In the pre-training stage, we use contrastive temporal prediction and spatial reconstruction as proxy tasks, which utilize the spatio-temporal information to learn the generic representations from EEG data; 2) In the fine-tuning stage, few data is used to calibrate the pre-trained model. We conduct extensive experiments on three emotion EEG datasets. The results demonstrate that our proposed model achieves excellent performance, with over 20% relative accuracy improvement and more than 15% improvement using only 1% labeled data.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Computer Science; Emotion; Electroencephalography (EEG); Neural Networks"}],"section":"Papers with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/93n3q505","frozenauthors":[{"first_name":"Ren-Jie","middle_name":"","last_name":"Dai","name_suffix":"","institution":"Shanghai Jiao Tong University","department":""},{"first_name":"Keya","middle_name":"","last_name":"Hu","name_suffix":"","institution":"School of Electronic Information and Electrical Engineering","department":""},{"first_name":"Haolong","middle_name":"","last_name":"Yin","name_suffix":"","institution":"Shanghai Jiao Tong University","department":""},{"first_name":"Bao-Liang","middle_name":"","last_name":"Lu","name_suffix":"","institution":"Shanghai Jiao Tong University","department":""},{"first_name":"Wei-Long","middle_name":"","last_name":"Zheng","name_suffix":"","institution":"Shanghai Jiao Tong University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/49447/galley/37409/download/"}]}
