摘要:

我们提出了一种新的方法,我们称之为AdaGTCN,从脑电图(EEG)和眼动(EM)数据中识别人类阅读意图,以帮助区分正常阅读和任务导向阅读。了解阅读过程的生理方面(认知负荷和阅读意图)可以帮助提高众包注释数据的质量。我们的方法,自适应图形时间卷积网络(AdaGTCN),使用自适应图形学习层和深度邻域图形卷积层,使用在单词级眼动注视期间记录的时间锁定EEG序列来识别阅读活动。自适应图形学习层动态学习EEG电极信号之间的空间相关性,而深度邻域图形卷积层利用来自密集图形邻域的时间特征来建立阅读任务识别的最新技术水平。我们将我们的方法与几个基线进行比较,报告ZuCo 2.0数据集的6.29%的改进,以及广泛的消融实验

英文摘要:

We present a new approach, that we call AdaGTCN, for identifying human reader intent from Electroencephalogram~(EEG) and Eye movement~(EM) data in order to help differentiate between normal reading and task-oriented reading. Understanding the physiological aspects of the reading process~(the cognitive load and the reading intent) can help improve the quality of crowd-sourced annotated data. Our method, Adaptive Graph Temporal Convolution Network (AdaGTCN), uses an Adaptive Graph Learning Layer and Deep Neighborhood Graph Convolution Layer for identifying the reading activities using time-locked EEG sequences recorded during word-level eye-movement fixations. Adaptive Graph Learning Layer dynamically learns the spatial correlations between the EEG electrode signals while the Deep Neighborhood Graph Convolution Layer exploits temporal features from a dense graph neighborhood to establish the state of the art in reading task identification over other contemporary approaches. We compare our approach with several baselines to report an improvement of 6.29% on the ZuCo 2.0 dataset, along with extensive ablation experiments
