人工智能论文:DASPS:基于心理刺激的焦虑状态数据库(DASPS: A Database for Anxious States based on a Psychological  Stimulation)焦虑影响人的能力和行为,同时影响生产力和生活质量。它可以被认为是抑郁和自杀的主要原因。由于获得认知,人类很容易察觉到焦虑状态,人类会解释对话者的语气,手势,面部表情并识别他们的精神状态。需要非侵入性可靠技术来执行焦虑检测的复杂任务。在本文中,我们通过面对面的心理刺激提出DASPS数据库,其中包含23名参与者在焦虑期间记录的脑电图(EEG)信号。 EEG信号采用Emotiv Epoc耳机捕获,因为它是无线可穿戴式低成本设备。在我们的研究中,我们调查不同参数的影响,特别是:试验持续时间,特征类型,特征组合和焦虑水平数。我们的研究结果表明,焦虑在1秒内得到很好的引发。例如,具有不同类型特征的堆叠稀疏自动编码器分别在2和4焦虑水平检测中达到83.50%和74.60%。所提出的结果证明了使用低成本EEG耳机而不是医疗非无线设备的好处,并为焦虑检测领域的新研究创造了一个起点。
Anxiety affects human capabilities and behavior as much as it affectsproductivity and quality of life.It can be considered as the main cause ofdepression and suicide.Anxious states are easily detectable by humans due totheir acquired cognition, humans interpret the interlocutor's tone of speech,gesture, facial expressions and recognize their mental state.There is a needfor non-invasive reliable techniques that performs the complex task of anxietydetection.In this paper, we present DASPS database containing recordedElectroencephalogram (EEG) signals of 23 participants during anxietyelicitation by means of face-to-face psychological stimuli.EEG signals werecaptured with Emotiv Epoc headset as it's a wireless wearable low-costequipment.In our study, we investigate the impact of different parameters,notably: trial duration, feature type, feature combination and anxiety levelsnumber.Our findings showed that anxiety is well elicited in 1 second.Forinstance, stacked sparse autoencoder with different type of features achieves83.50% and 74.60% for 2 and 4 anxiety levels detection, respectively.Thepresented results prove the benefits of the use of a low-cost EEG headsetinstead of medical non-wireless devices and create a starting point for newresearches in the field of anxiety detection.人工智能论文:DASPS:基于心理刺激的焦虑状态数据库(DASPS: A Database for Anxious States based on a Psychological  Stimulation) hIfzdF858u38Pf55.jpg
