SG-DSN: A Semantic Graph-based Dual-Stream Network for facial expression recognition
SG-DSN: یک شبکه جریان دوگانه مبتنی بر نمودار معنایی برای تشخیص حالت چهره-2021 Facial expression recognition (FER) is a crucial task for human emotion analysis and has attracted wide interest in the field of computer vision and affective computing. General convolutional-based FER meth- ods rely on the powerful pattern abstraction of deep models, but they lack the ability to use semantic information behind significant facial areas in physiological anatomy and cognitive neurology. In this work, we propose a novel approach for expression feature learning called Semantic Graph-based Dual- Stream Network (SG-DSN), which designs a graph representation to model key appearance and geometric facial changes as well as their semantic relationships. A dual-stream network (DSN) with stacked graph convolutional attention blocks (GCABs) is introduced to automatically learn discriminative features from the organized graph representation and finally predict expressions. Experiments on three lab-controlled datasets and two in-the-wild datasets demonstrate that the proposed SG-DSN achieves competitive performance compared with several latest methods.© 2021 Published by Elsevier B.V.

Emotional editing constraint conversation content generation based on reinforcement learning
ویرایش احساسی تولید محتوای مکالمه محدود بر اساس یادگیری تقویتی-2020 In recent years, the generation of conversation content based on deep neural networks has attracted many re- searchers. However, traditional neural language models tend to generate general replies, lacking logical and emotional factors. This paper proposes a conversation content generation model that combines reinforcement learning with emotional editing constraints to generate more meaningful and customizable emotional replies. The model divides the replies into three clauses based on pre-generated keywords and uses the emotional editor to further optimize the final reply. The model combines multi-task learning with multiple indicator rewards to comprehensively optimize the quality of replies. Experiments shows that our model can not only improve the fluency of the replies, but also significantly enhance the logical relevance and emotional relevance of the replies.

Memory level neural network: A time-varying neural network for memory input processing
شبکه عصبی سطح حافظه: یک شبکه عصبی با زمان متفاوت برای پردازش ورودی حافظه-2020 Affective computing is an important foundation for implementing brain-like computing and advanced
machine intelligence. However, the instantaneous and memory fusion input characteristic makes current
neural networks not suitable for affective computing. In this paper, we propose an affective computing
oriented memory level neural network. A ‘‘switch” has been added to the memory level neurons, which
will achieve a transition from the instantaneous input to the memory input when the temporal integration
of inputs above a certain threshold. Then, the ‘‘switch” is continualized by an adjustable sigmoid
function whose parameters are tuned to adjust the speed of the transition and the mixing ratio of the
two inputs. Multiple memory level neurons form a deep time-varying neural network capable of handling
fusional inputs. We demonstrate on both process datasets and static datasets that the memory level neural
network successfully converges on both datasets and meets the error accuracy requirements. Keywords: Memory level neuron | Affective computing | Memory level transition | Time-related memory input | Time-varying output | MLNN |

Multimodal big data affective analytics: A comprehensive survey using text, audio, visual and physiological signals
تجزیه و تحلیل عاطفی داده های بزرگ چند متغیره: یک مرور جامع با استفاده از سیگنال های متنی ، صوتی ، تصویری و فیزیولوژیکی-2020 Affective computing is an emerging multidisciplinary research field that is increasingly drawing the attention of
researchers and practitioners in various fields, including artificial intelligence, natural language processing,
cognitive and social sciences. Research in affective computing includes areas such as sentiment, emotion, and
opinion modelling. The internet is an excellent source of data required for sentiment analysis, such as customer
reviews of products, social media, forums, blogs, etc. Most of these data, called big data, are unstructured and
unorganized. Hence there is a strong demand for developing suitable data processing techniques to process these
rich and valuable data to produce useful information. Early surveys on sentiment and emotion recognition in the
literature have been limited to discussions using text, audio, and visual modalities. So far, to the authors
knowledge, a comprehensive survey combining physiological modalities with these other modalities for affective
computing has yet to be reported. The objective of this paper is to fill the gap in this surveyed area. The usage of
physiological modalities for affective computing brings several benefits in that the signals can be used in different
environmental conditions, more robust systems can be constructed in combination with other modalities, and it
has increased anti-spoofing characteristics. The paper includes extensive reviews on different frameworks and
categories for state-of-the-art techniques, critical analysis of their performances, and discussions of their applications,
trends and future directions to serve as guidelines for readers towards this emerging research area. Keywords: Affective computing | Multimodal fusion | Sentiment databases | Sentiment analysis | Affective applications |

A mobile application to report and detect 3D body emotional poses
یک برنامه کاربردی تلفن همراه برای گزارش و کشف نکات سه بعدی عاطفی بدن-2019 Most research into automatic emotion recognition is focused on facial expressions or physiological signals, while the exploitation of body postures has scarcely been explored, although they can be useful for emo- tion detection. This paper first explores a mechanism for self-reporting body postures with a novel easy- to-use mobile application called EmoPose. The app detects emotional states from self-reported poses, classifying them into the six basic emotions proposed by Ekman and a neutral state. The poses identi- fied by Schindler et al. have been used as a reference and the nearest neighbor algorithm used for the classification of poses. Finally, the accuracy in detecting emotions has been assessed by means of poses reported by a sample of users.

Cognitive-affective regulation process for micro-expressions based on Gaussian cloud distribution
فرایند تنظیم عاطفی شناختی برای بیان میکرو براساس توزیع ابری گاوسی-2017 In this paper, we explore the process of emotional state transition. And the process is impacted by emotional state of interaction objects. First of all, the cognitive reasoning process and the micro-expressions recognition is the basis of affective computing adjustment process. Secondly, the threshold function and attenuation function are proposed to quantify the emotional changes. In the actual environment, the emotional state of the robot and external stimulus are also quantified as the transferring probability. Finally, the Gaussian cloud distribution is introduced to the Gross model to calculate the emotional transitional probabilities. The experimental results show that the model in humanecomputer interaction can effectively regulate the emotional states, and can significantly improve the humanoid and intelligent ability of the robot. This model is consistent with experimental and emulational significance of the psychology, and allows the robot to get rid of the mechanical emotional transfer process.Copyright © 2016, Chongqing University of Technology.

TensiStrength: Stress and relaxation magnitude detection for social media texts
TensiStrength: تشخیص اندازه استرس و ارامش برای متون رسانه های اجتماعی-2017 Computer systems need to be able to react to stress in order to perform optimally on
some tasks. This article describes TensiStrength, a system to detect the strength of stress
and relaxation expressed in social media text messages. TensiStrength uses a lexical ap
proach and a set of rules to detect direct and indirect expressions of stress or relaxation,
particularly in the context of transportation. It is slightly more effective than a compara
ble sentiment analysis program, although their similar performances occur despite differ
ences on almost half of the tweets gathered. The effectiveness of TensiStrength depends on
the nature of the tweets classified, with tweets that are rich in stress-related terms being
particularly problematic. Although generic machine learning methods can give better per
formance than TensiStrength overall, they exploit topic-related terms in a way that may
be undesirable in practical applications and that may not work as well in more focused
contexts. In conclusion, TensiStrength and generic machine learning approaches work well
enough to be practical choices for intelligent applications that need to take advantage of
stress information, and the decision about which to use depends on the nature of the texts
analysed and the purpose of the task.

Affective experience modeling based on interactive synergetic dependence in big data
مدل سازی تجربه موثر بر اساس وابستگی توأم تعاملی در داده های های بزرگ-2015 Affective computing is important in human–computer interaction. Especially in interactive cloud computing within big data, affective modeling and analysis have extremely high complexity and uncertainty
for emotional status as well as decreased computational accuracy. In this paper, an approach for affective experience evaluation in an interactive environment is presented to help enhance the significance of
those findings. Based on a person-independent approach and the cooperative interaction as core factors,
facial expression features and states as affective indicators are applied to do synergetic dependence evaluation and to construct a participant’s affective experience distribution map in interactive Big Data space.
The resultant model from this methodology is potentially capable of analyzing the consistency between a
participant’s inner emotional status and external facial expressions regardless of hidden emotions within
interactive computing. Experiments are conducted to evaluate the rationality of the affective experience
modeling approach outlined in this paper. The satisfactory results on real-time camera demonstrate an
availability and validity comparable to the best results achieved through the facial expressions only from
reality big data. It is suggested that the person-independent model with cooperative interaction and synergetic dependence evaluation has the characteristics to construct a participant’s affective experience distribution, and can accurately perform real-time analysis of affective experience consistency according to interactive big data. The affective experience distribution is considered as the most individual intelligent
method for both an analysis model and affective computing, based on which we can further comprehend
affective facial expression recognition and synthesis in interactive cloud computing.
