Language,modality, and mobile media use experiences: Social responses to smartphone cues in a task-oriented context

With people’s growing use of virtual agents and voice assistants on smartphones, researchers have pointed out that mobile phones are not only acting as intermediaries that connect users from different places, but also communication terminals that present different combinations of social cues. This study applies the Computers are Social Actors paradigm in human-phone interaction and postulates that compared to non-anthropomorphic language and text cues, anthropomorphic language and vocal cues will have more effects on users’ social responses to smartphones. This study also explores the role of individual differences in users’ social responses to smartphones. Based on a lab experiment using a between-subjects factorial design, the study suggests that although anthropomorphic language and voice-based information did not have main effects on users’ social responses, people’s mobile media usage and intensive phone use interacted with these cues in their social responses to the smartphones. In addition, this study implies that it is the combination of social cues, individual differences, and communication contexts that contributes to people’s social reactions to the smartphones. The findings of the study can inform user interface design and precipitate further discussion about the ethical issues in human-phone interaction.     

A Resilient Control Strategy for Cyber-Physical Systems Subject to Denial of Service Attacks: A Leader-Follower Set-Theoretic Approach

Multi-agent systems are usually equipped with open communication infrastructures to improve interactions efficiency, reliability and sustainability. Although technologically cost-effective, this makes them vulnerable to cyber-attacks with potentially catastrophic consequences. To this end, we present a novel control architecture capable to deal with the distributed constrained regulation problem in the presence of time-delay attacks on the agents’ communication infrastructure. The basic idea consists of orchestrating the interconnected cyber-physical system as a leader-follower configuration so that adequate control actions are computed to isolate the attacked unit before it compromises the system operations. Simulations on a multi-area power system confirm that the proposed control scheme can reconfigure the leader-follower structure in response to denial of-service (DoS) attacks.      

基于SLE范式的社群化制造计算实验比较研究

在互联社会背景下,先进的制造模式需要从信息、社交和服务等方面实现企业内部、跨企业间的协作。社群化制造作为 一种适应未来社会化、服务化和大规模个性化制造环境的新型制造模式,将解决未来制造业中多参与主体资源共享、协作与交互等问题,因此对其进行研究具有重要意义。然而,社群化制造系统的复杂性又会导致其建模困难以及协作策略难以评估等问题,这引起了众多研究者的关注。因此,提出一种基于SLE范式的社群化制造计算模型,包括个体模型、交互模型与社会模型3个部分,并进一步引入了“计算实验”的思想,通过计算实验验证了这种计算模型是有效且可行的,对社群化制造的研究起到了一定的推动作用。     

综合维度学习的多群协作粒子群优化算法

针对维度学习策略（dimensional learning strategy,DLS）中存在的过度开发问题,提出了一种综合维度学习的多群协作粒子群优化算法（CDL-MCPSO）。为提高种群搜索效率,采用基于主从范式的集群结构,将种群划分为一个主群和四个从群,主群执行综合学习策略在搜索空间进行大范围探索,从群执行综合维度学习策略（comprehensive dimensional learning,CDL）在局部最优解附近进行高精度的开发,主从群通过执行具有不同职能的算法能够有效实现其在勘探和开发之间的平衡;同时为保持种群多样性,提出了一种新的解交换机制（SEM）用于在主从群独立运行各自算法若干代之后进行信息的交流与协作,以指导粒子后期进行更准确的搜索;最后,针对初始化过程随机性过高,运用拉丁超立方体采样方法对算法重建输入分布。为验证CDL-MCPSO的有效性,将其与五种粒子群算法变体在10个测试函数上进行实验对比,结果表明该算法总是可以找到优于或相当于对比算法的解,在求解复杂函数时具有可行性和高效性。     

基于熟悉人脸范式的P300脑机接口字符输入系统的设计与实现

脑机接口系统是一种使大脑能够不依赖于外周神经和肌肉通道,与外部环境进行交互的系统。基于P300的脑机接口字符输入系统是脑机接口技术的一种典型应用。对基于传统范式的P300脑机接口系统进行改进,设计并实现了基于熟悉人脸范式的P300脑机接口字符输入系统。实验建立了基于熟悉人脸的P300脑机接口系统的信号采集与处理模型,对采集到的数据进行预处理、特征提取,并使用集成支持向量机算法对脑电信号进行分类。结果表明,除P300电位外,熟悉人脸范式诱发出了Vpp和N170电位。与以往传统范式80.6%的字符输入正确率相比,基于熟悉人脸范式的字符输入正确率达到93.5%,具有良好的发展前景。     

Autonomic correlates of chronic schizophrenia: A reaction time paradigm.

Assessed basal, tonic, and 2 phasic measures of heart rate and skin conductance among 16 drug-free, chronic, process, nonparanoid schizophrenics, and 2 groups of control Ss (hospital staff and prison inmates). Of particular interest were changes in autonomic activity that attended manipulation of "go" signal intensity within a reaction time paradigm. Among control Ss, increased signal intensity produced increases in tonic levels and amplitude of anticipatory responding. Among schizophrenics, however, the reverse occurred: Increased signal intensity resulted in decreased tonic levels and inhibition of anticipatory responding. Schizophrenic responses occurred in the absence of basal level differences between groups. Results are interpreted as indicating the presence of a learned anticipatory set that serves to reduce the impact of stimulus intensity. This inhibitory set would also appear to reduce receptivity to the cue component of stimuli. (16 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

面向倾向性分析的基于词聚类的基准词选择方法*

现有的基准词选择方法存在着随机性和主观性的缺陷,提出了一种基于词聚类的基准词的选择方法：从目标领域本体中选出一组初始种子词进行扩展,聚类得出二代种子词,对二代种子词再进行扩展、聚类,依次迭代直至得到最优的聚类种子词,并作为最终选取的基准词。实验结果表明该方法提取的基准词在词的情感倾向分类中具有较高的准确率。
