Most studies have demonstrated that EEG can be applied to emotion recognition. In the process of EEG-based emotion recognition, real-time is an important feature. In this paper, the real-time problem of emotion recognition based on EEG is explained and analyzed. Secondly, the short time window length and attention mechanisms are designed on EEG signals to follow emotion change over time. Then, long short-term memory with the additive attention mechanism is used for emotion recognition, due to timely emotion updates, and the model is applied to the SEED and SEED-IV datasets to verify the feasibility of real-time emotion recognition. The results show that the model performs relatively well in terms of real-time performance, with accuracy rates of 85.40% and 74.26% on SEED and SEED-IV, but the accuracy rate has not reached the ideal state due to data labeling and other losses in the pursuit of real-time performance.
大多数研究已经证明脑电图(EEG)可应用于情感识别。在基于 EEG 的情感识别过程中,实时性是一个重要特征。本文解释和分析了基于 EEG 的情感识别中的实时问题。其次,针对 EEG 信号设计了短时间窗口长度和注意力机制,以跟踪随时间变化的情感。然后,使用具有加性注意力机制的长短期记忆(LSTM)进行情感识别,由于能够及时更新情感,因此将模型应用于 SEED 和 SEED-IV 数据集以验证实时情感识别的可行性。结果表明,该模型在实时性能方面表现相对较好,在 SEED 和 SEED-IV 上的准确率分别为 85.40%和 74.26%,但由于数据标签和实时性能追求等方面的损失,准确率尚未达到理想状态。
