基于EMD的改进MFCC的语音情感识别

人在不同情感下的语音信号其非平稳性尤为明显,传统的MFCC只能反映语音信号的静态特征,经验模态分解能够精细地刻画语音信号的非平稳特性。为提取情感语音的非平稳特征,用经验模态分解将情感语音信号分解为一系列固有模态函数分量,通过Mel滤波器后取其对数能量,进行DCT反变换后得到改进的MFCC作为情感识别的新特征,采用支持向量机对高兴、生气、厌烦和恐惧等四种语音情感识别。仿真实验结果表明：改进的MFCC识别率达到77.17%,在不同的信噪比下,识别率最大可提高3.26%。     

基于混合神经网络的脑电时空特征情感分类

提出一种脑电图（electroencephalograph,简称EEG）数据表示方法,将一维链式EEG向量序列转换成二维网状矩阵序列,使矩阵结构与EEG电极位置的脑区分布相对应,以此来更好地表示物理上多个相邻电极EEG信号之间的空间相关性.再应用滑动窗将二维矩阵序列分成一个个等长的时间片段,作为新的融合了EEG时空相关性的数据表示.还提出了级联卷积-循环神经网络（CASC_CNN_LSTM）与级联卷积-卷积神经网络（CASC_CNN_CNN）这两种混合深度学习模型,二者都通过CNN卷积神经网络从转换的二维网状EEG数据表示中捕获物理上相邻脑电信号之间的空间相关性,而前者通过LSTM循环神经网络学习EEG数据流在时序上的依赖关系,后者则通过CNN卷积神经网络挖掘局部时间与空间更深层的相关判别性特征,从而精确识别脑电信号中包含的情感类别.在大规模脑电数据集DEAP上进行被试内效价维度上两类情感分类实验,结果显示,所提出的CASC_CNN_LSTM和CASC_CNN_CNN网络在二维网状EEG时空特征上的平均分类准确率分别达到93.15%和92.37%,均高于基准模型和现有最新方法的性能,表明该模型有效提高了EEG情感识别的准确率和鲁棒性,可以有效地应用到基于EEG的情感分类与识别相关应用中.

光影诗篇——墨西哥建筑艺术中的地域智慧与启迪

强烈的光照作为墨西哥一个十分突出的地域特征,对墨西哥的气候、文化乃至民众的生活习惯都产生了巨大的影响。墨西哥建筑师敏锐地捕捉到这一特征,融入自己的理解和想象,在光影与空间的交织、变化中呈现出丰富的情感色彩,使得建筑与人之间建立起直触心灵的对话。随着时代的变迁和文化的发展,建筑所要实现的功能、表达的情感在不断改变,而建筑师们对于光影的处理手段也趋于多元化,从而产生了越来越多极具特色的建筑形式。通过对墨西哥不同历史时期建筑的分析,来研究墨西哥建筑师运用光影塑造不同情感空间的多种手法和传承关系。     

Parenting at risk: New perspectives, new approaches.

In this lead paper for this special section, we advance the perspective that new insights into parenting at risk can be gained by focusing on the dynamic emotional processes that occur during parent–child exchanges, with special emphasis on parental emotions as experienced and their regulation of emotion and underlying cognitions, as well as the role of developmentally rooted cognitions in shaping these associations. We discuss the very few but germinal studies that embody this perspective and introduce work in this section that examines emotion dynamics during parenting in real time. We believe this perspective will move us beyond static conceptualizations of parenting at risk, broadens our understanding of parenting as a process, and accelerates our ability to identify the essential targets of intervention when parenting is at risk.

Review of Psychodynamic techniques: Working with emotion in the therapeutic relationship.

Reviews the book, Psychodynamic techniques: Working with emotion in the therapeutic relationship by Karen J. Maroda (see record 2010-01318-000). What makes Maroda’s work particularly remarkable, however, is that she not only manages to identify and explicate aspects of technique, but that the range of skills she addresses all converge on what can seem like an especially mystifying topic to new clinicians: the use of emotion in the therapeutic relationship. Maroda’s pragmatic tone seems to effortlessly weave concrete skills through the particularly vaporous topic of using emotion productively. The result is an admirably unmechanistic set of principles to aid clinicians in navigating the complex emotional terrain of the therapeutic relationship in a manner consistent with their own personal styles. One of the major strengths of Psychodynamic techniques is its breadth, and Maroda provides a good balance, including both general and specific issues related to the role of emotion in the therapeutic process. Despite the overall consistency of her attunement to the experience of the newer clinician, some of what Maroda stresses as vital to the therapeutic relationship may be unrealistic. The process of reading the book parallels the process of a successful therapy in which one has come to engage with and trust her guide and emerges a more flexible, confident, insightful person and professional. Maroda’s continued reassurances and frank openness to sharing her own vulnerabilities leaves the reader feeling infused with a sense of possibility that a fuller, deeper therapeutic relationship is possible.

Thanks, but I'm used to better: A relative rank model of gratitude.

We argue that more help does not necessarily lead to more gratitude. Rather, gratitude depends on how a given instance of help compares with the help that a person is used to receiving. Participants read vignettes detailing an event in which 11 different friends either lent them varying amounts of money or spent varying amounts of time providing help. The amount of gratitude elicited by a given amount of help (e.g., a loan of ￡36 [about $56] or 49 min help) differed substantially depending on how this amount ranked among the help they were getting from their other friends. Comparison across four experimental conditions suggested that these judgments operated via the same general cognitive mechanisms used to judge other social events and psychophysical stimuli (as outlined by range frequency theory). Although more help does lead to more gratitude, people appear to be sensitive to how that help compares with what others are providing, and experienced gratitude depends on these relative judgments.

Deficits in emotion-regulation skills predict alcohol use during and after cognitive–behavioral therapy for alcohol dependence.

Objective: As emotion regulation is widely considered to be a primary motive in the misuse of alcohol, our aim in the study was to investigate whether deficits in adaptive emotion-regulation skills maintain alcohol dependence (AD). Method: A prospective study investigated whether emotion-regulation skills were associated with AD and whether these skills predicted alcohol use during and after treatment for AD. Participants were 116 individuals treated for AD with cognitive–behavioral therapy. Emotion regulation and severity of AD symptoms were assessed by self-report. Alcohol use during treatment was assessed by Breathalyzer and urine analysis for ethyl glucuronide; alcohol use during the 3-month follow-up interval was assessed by self-report. Results: Pretreatment emotion-regulation skills predicted alcohol use during treatment, and posttreatment emotion-regulation skills predicted alcohol use at follow-up, even when controlling for other predictors potentially related to emotion regulation. Among a broad range of specific emotion-regulation skills, the ability to tolerate negative emotions was the only skill that negatively predicted subsequent alcohol consumption when controlling for the other skills. Individuals in the AD sample reported significantly larger deficits in emotion-regulation skills than did those in a nonclinical control sample but significantly less than did those in a sample of individuals exclusively meeting criteria for major depressive disorder. Conclusions: Enhancement of general emotion-regulation skills, especially the ability to tolerate negative emotions, appears to be an important target in the treatment of AD.
