ACII 2009: Affective Computing and Intelligent Interaction. Proceedings of the Doctoral Consortium
This volume collects the contributions presented at the ACII 2009 Doctoral Consortium, the event aimed at gathering PhD students with the goal of sharing ideas about the theories behind affective computing; its development; and its application. Published papers have been selected out a large number of high quality submissions covering a wide spectrum of topics including the analysis of human-human, human-machine and human-robot interactions, the analysis of physiology and nonverbal behavior in affective phenomena, the effect of emotions on language and spoken interaction, and the embodiment of affective behaviors
Neural network based architectures for aerospace applications
A brief history of the field of neural networks research is given and some simple concepts are described. In addition, some neural network based avionics research and development programs are reviewed. The need for the United States Air Force and NASA to assume a leadership role in supporting this technology is stressed
Technology assessment of advanced automation for space missions
Six general classes of technology requirements derived during the mission definition phase of the study were identified as having maximum importance and urgency, including autonomous world model based information systems, learning and hypothesis formation, natural language and other man-machine communication, space manufacturing, teleoperators and robot systems, and computer science and technology
Intelligent solution for automatic online exam monitoring
E-learning has shown significant growth in recent years due to its unavoidable benefits in unexpected situations such as the coronavirus disease 2019 (COVID-19) pandemic. Indeed, online exam is a very important component of an online learning program. It allows higher education institutions to assess student learning outcomes. However, cheating in exams is a widespread phenomenon worldwide, which creates several challenges in terms of integrity, reliability and security of online examinations. In this study, we propose a continuous authentication system for online exam. Our intelligent inference system based on machine learning algorithms and rules, detects continuously any inappropriate behavior in order to limit and prevent fraud. The proposed model includes several modules to enhance security, namely the registration module, the continuous students’ identity verification and control module, the live video stream and the end-to-end sessions recording
Online shopping behavior study based on multi-granularity opinion mining: China vs. America
With the development of e-commerce, many products are now being sold
worldwide, and manufacturers are eager to obtain a better understanding of
customer behavior in various regions. To achieve this goal, most previous
efforts have focused mainly on questionnaires, which are time-consuming and
costly. The tremendous volume of product reviews on e-commerce websites has
seen a new trend emerge, whereby manufacturers attempt to understand user
preferences by analyzing online reviews. Following this trend, this paper
addresses the problem of studying customer behavior by exploiting recently
developed opinion mining techniques. This work is novel for three reasons.
First, questionnaire-based investigation is automatically enabled by employing
algorithms for template-based question generation and opinion mining-based
answer extraction. Using this system, manufacturers are able to obtain reports
of customer behavior featuring a much larger sample size, more direct
information, a higher degree of automation, and a lower cost. Second,
international customer behavior study is made easier by integrating tools for
multilingual opinion mining. Third, this is the first time an automatic
questionnaire investigation has been conducted to compare customer behavior in
China and America, where product reviews are written and read in Chinese and
English, respectively. Our study on digital cameras, smartphones, and tablet
computers yields three findings. First, Chinese customers follow the Doctrine
of the Mean, and often use euphemistic expressions, while American customers
express their opinions more directly. Second, Chinese customers care more about
general feelings, while American customers pay more attention to product
details. Third, Chinese customers focus on external features, while American
customers care more about the internal features of products
Artificial Intelligence : from Research to Application ; the Upper-Rhine Artificial Intelligence Symposium (UR-AI 2019)
The TriRhenaTech alliance universities and their partners presented their
competences in the field of artificial intelligence and their cross-border
cooperations with the industry at the tri-national conference 'Artificial
Intelligence : from Research to Application' on March 13th, 2019 in Offenburg.
The TriRhenaTech alliance is a network of universities in the Upper Rhine
Trinational Metropolitan Region comprising of the German universities of
applied sciences in Furtwangen, Kaiserslautern, Karlsruhe, and Offenburg, the
Baden-Wuerttemberg Cooperative State University Loerrach, the French university
network Alsace Tech (comprised of 14 'grandes \'ecoles' in the fields of
engineering, architecture and management) and the University of Applied
Sciences and Arts Northwestern Switzerland. The alliance's common goal is to
reinforce the transfer of knowledge, research, and technology, as well as the
cross-border mobility of students

DeepBreath: Deep Learning of Breathing Patterns for Automatic Stress Recognition using Low-Cost Thermal Imaging in Unconstrained Settings
We propose DeepBreath, a deep learning model which automatically recognises
people's psychological stress level (mental overload) from their breathing
patterns. Using a low cost thermal camera, we track a person's breathing
patterns as temperature changes around his/her nostril. The paper's technical
contribution is threefold. First of all, instead of creating hand-crafted
features to capture aspects of the breathing patterns, we transform the
uni-dimensional breathing signals into two dimensional respiration variability
spectrogram (RVS) sequences. The spectrograms easily capture the complexity of
the breathing dynamics. Second, a spatial pattern analysis based on a deep
Convolutional Neural Network (CNN) is directly applied to the spectrogram
sequences without the need of hand-crafting features. Finally, a data
augmentation technique, inspired from solutions for over-fitting problems in
deep learning, is applied to allow the CNN to learn with a small-scale dataset
from short-term measurements (e.g., up to a few hours). The model is trained
and tested with data collected from people exposed to two types of cognitive
tasks (Stroop Colour Word Test, Mental Computation test) with sessions of
different difficulty levels. Using normalised self-report as ground truth, the
CNN reaches 84.59% accuracy in discriminating between two levels of stress and
56.52% in discriminating between three levels. In addition, the CNN
outperformed powerful shallow learning methods based on a single layer neural
network. Finally, the dataset of labelled thermal images will be open to the
community.Comment: Submitted to "2017 7th International Conference on Affective

MoCog1: A computer simulation of recognition-primed human decision making
The results of the first stage of a research effort to develop a 'sophisticated' computer model of human cognitive behavior are described. Most human decision making is an experience-based, relatively straight-forward, largely automatic response to internal goals and drives, utilizing cues and opportunities perceived from the current environment. The development of the architecture and computer program (MoCog1) associated with such 'recognition-primed' decision making is discussed. The resultant computer program was successfully utilized as a vehicle to simulate earlier findings that relate how an individual's implicit theories orient the individual toward particular goals, with resultant cognitions, affects, and behavior in response to their environment
