About The Workshop

Novel applications of affective computing have emerged in recent years in domains ranging from health care to the 5th generation mobile network. Many of these have found improved emotion classification performance when fusing multiple sources of data (e.g., audio, video, brain, face, thermal, physiological, environmental, positional, text, etc.). Multimodal affect recognition has the potential to revolutionize the way various industries and sectors utilize information gained from recognition of a person's emotional state, particularly considering the flexibility in the choice of modalities and measurement tools (e.g., surveillance versus mobile device cameras). Multimodal classification methods have been proven highly effective at minimizing misclassification error in practice and in dynamic conditions. Further, multimodal classification models tend to be more stable over time compared to relying on a single modality, increasing their reliability in sensitive applications such as mental health monitoring and automobile driver state recognition. To continue the trend of lab to practice within the field and encourage new applications of affective computing, this workshop provides a forum for researchers to exchange ideas on future directions, including novel fusion methods and databases, innovations through interdisciplinary research, and emerging emotion sensing devices. Also, this workshop places a focus on the ethical use of novel applications of affective computing in real world scenarios. More specifically, it welcomes discussions on topics including, but not limited to, privacy, manipulation of users, and public fears and misconceptions regarding affective computing. It is expected that the affective computing market will grow from $28.6 billion to $140 billion by 2025. This significant growth will allow for new applications into affective computing that include, but are not limited to, health monitoring systems, diagnosis and treatment of disorders such as Autism Spectrum Disorder, and home entertainment (e.g., video games). To improve these affective systems, there are many ethical concerns to be considered. This workshop seeks to explore the intersection between theory and ethical applications of affective computing, with a specific focus on multimodal data for affect recognition (e.g., expression, and physiological signals).

To investigate ethical, applied affect recognition, this workshop will leverage multimodal data that includes, but is not limited to, 2D, 3D, thermal, brain, physiological, and mobile sensor signals. This workshop aims to expose current use cases for affective computing and emerging applications of affective computing to spark future work. Along with this, this workshop has a specific focus on the ethical considerations of such work, including how to mitigate ethical concerns. Considering this, topics of the workshop will focus on questions including, but not limited to:

  • What inter-correlations exist between facial affect (e.g. expression) and other modalities (e.g. EEG)?
  • How can multimodal data be leveraged to create real-world applications of affect recognition such as prediction of stress, real-time ubiquitous emotion recognition, and impact of mood on ubiquitous subject identification?
  • How can we facilitate the collection of multimodal data for applied affect recognition?
  • What are the ethical implications of working on such questions?
  • How can we mitigate the ethical concerns that such work produces?
  • Can we positively address public fears and misconceptions regarding applied affective computing?
To address these questions, AMAR2021 targets researchers in BCI, affective computing, biometrics, computer vision, human-computer interaction, behavioral sciences, social sciences, and policy makers who are interested in leveraging multimodal data for ethical, applied affect recognition.

Topics of interest include, but are not limited to, ethical applications of the following:
  • Health applications with a focus on multimodal affect
  • Multimodal affective computing for cybersecurity applications (e.g., biometrics and IoT security)
  • Inter-correlations and fusion of ubiquitous multimodal data as it relates to applied emotion recognition (e.g. face and EEG data)
  • Leveraging ubiquitous devices to create reliable multimodal applications for emotion recognition
  • Applications of in-the-wild data vs. lab controlled
  • Facilitation and collection of multimodal data (e.g. ubiquitous data) for applied emotion recognition
  • Engineering applications of multimodal affect (e.g., robotics, social engineering, domain inspired hardware / sensing technologies, etc.)

Real-time Ubiquitous Pain Recognition
Iyonna Tynes and Shaun Canavan
Emotion recognition is a quickly growing field due to the increased interest in building systems which can classify and respond to emotions. Recent medical crises, such as the opioid overdose epidemic in the United States and the global COVID-19 pandemic has emphasized the importance of emotion recognition applications is areas like Telehealth services. Considering this, we propose an approach to real-time ubiquitous pain recognition from facial images. We have conducted offline experiments using the BP4D dataset, where we investigate the impact of gender and data imbalance. This paper proposes an affordable and easily accessible system which can perform pain recognition inferences. The results from this study found a balanced dataset, in terms of class and gender, results in the highest accuracies for pain recognition. We also detail the difficulties of pain recognition using facial images and propose some future work that can be investigated for this challenging problem.

Attentive Cross-modal Connections for Deep Multimodal Wearable-based Emotion Recognition
Anubhav Bhatti, Behnam Behinaein, Dirk Rodenburg, Paul Hungler and Ali Etemad
Classification of human emotions can play an essential role in the design and improvement of human-machine systems. While individual biological signals such as Electrocardiogram (ECG) and Electrodermal Activity (EDA) have been widely used for emotion recognition with machine learning methods, multimodal approaches generally fuse extracted features or final classification/regression results to boost performance. To enhance multimodal learning, we present a novel attentive cross-modal connection to share information between convolutional neural networks responsible for learning individual modalities. Specifically, these connections improve emotion classification by sharing intermediate representations among EDA and ECG and apply attention weights to the shared information, thus learning more effective multimodal embeddings. We perform experiments on the WESAD dataset to identify the best configuration of the proposed method for emotion classification. Our experiments show that the proposed approach is capable of learning strong multimodal representations and outperforms a number of baselines methods.

HirePreter: A Framework for Providing Fine-grained Interpretation for Automated Job Interview Analysis
Wasifur Rahman, Sazan Mahbub, Asif Salekin, Md Kamrul Hasan and Ehsan Hoque
There has been a rise in automated technologies to screen potential job applicants through affective signals captured from video-based interviews. These tools can make the interview process scalable and objective, but they often provide little to no information of how the machine learning model is making crucial decisions that impacts the livelihood of thousands of people. We built an ensemble model -- by combining Multiple-Instance-Learning and Language-Modeling based models -- that can predict whether an interviewee should be hired or not. Using both model-specific and model-agnostic interpretation techniques, we can decipher the most informative time-segments and features driving the model’s decision making. Our analysis also shows that our models are significantly impacted by the beginning and ending portions of the video. Our model achieves 75.3% accuracy in predicting whether an interviewee should be hired on the ETS Job Interview dataset. Our approach can be extended to interpret other video-based affective computing tasks like analyzing sentiment, measuring credibility, or coaching individuals to collaborate more effectively in a team.

Quantifying the Intensity of Toxicity for Discussions and Speakers
Samiha Samrose and Ehsan Hoque
In this work, from YouTube News-show multimodal dataset with dyadic speakers having heated discussions, we analyze the toxicity through audio-visual signals. Firstly, as different speakers may contribute differently towards the toxicity, we propose a speaker-wise toxicity score revealing individual proportionate contribution. As discussions with disagreements may reflect some signals of toxicity, in order to identify discussions needing more attention we categorize discussions into binary high-low toxicity levels. By analyzing visual features, we show that the levels correlate with facial expressions as Upper Lid Raiser (associated with 'surprise'), Dimpler (associated with 'contempt'), and Lip Corner Depressor (associated with 'disgust') remain statistically significant in separating high-low intensities of disrespect. Secondly, we investigate the impact of audio-based features such as pitch and intensity that can significantly elicit disrespect, and utilize the signals in classifying disrespect and non-disrespect samples by applying logistic regression model achieving 79.86% accuracy. Our findings shed light on the potential of utilizing audio-visual signals in adding important context towards understanding toxic discussions
