van der Meer, M.T. (author), Liscio, E. (author), Jonker, C.M. (author), Plaat, Aske (author), Vossen, Piek (author), Murukannaiah, P.K. (author)The key arguments underlying a large and noisy set of opinions help understand the opinions quickly and accurately. Fully automated methods can extract arguments but (1) require large labeled datasets and (2) work well for known viewpoints, but not for novel points of view. We propose HyEnA, a hybrid (human + AI) method for extracting...conference paper 2022

Kola, I. (author), Isufaj, R. (author), Jonker, C.M. (author)Personal values represent what people find important in their lives, and are key drivers of human behavior. For this reason, support agents should provide help that is aligned with the personal values of the users. To do this, the support agent not only should know the value preferences of the user, but also how different situations in the...conference paper 2022

Liu, X. (author), Achterberg, M.A. (author), Kooij, Robert (author)pinion dynamics models study how the interaction among people influences the opinion formation process. In most opinion dynamics models, only one opinion can exist in the steady state, which is different from the real-life opinion formation process. In 2009, Shao et at. introduced a Non-Consensus Opinion (NCO) model, which allows different...conference paper 2022

Giuffré, A. (author), Colonna, Piero (author), Pini, M. (author)The environmental control system (ECS) is the largest auxiliary power consumer, i.e, around 75% of non-propulsive power, among the aircraft subsystems. The adoption of a novel ECS architecture, based on an electrically-driven vapor compression cycle system, can enable a twofold increase of coefficient of performance (COP), as compared to the...conference paper 2022

Starre, R.A.N. (author), Loog, M. (author), Oliehoek, F.A. (author)Model-based reinforcement learning methods are promising since they can increase sample efficiency while simultaneously improving generalizability. Learning can also be made more efficient through state abstraction, which delivers more compact models. Model-based reinforcement learning methods have been combined with learning abstract models to...conference paper 2022

(author), Siang Ang, Chee (author)With one-person households being increasingly common and Covid-19 lockdown policies forcing people to stay home, remote dining has become common practice for many, who take it as an opportunity to connect with others in times of loneliness. Sharing meals online, also known as digital commensality, is a rich form of interaction, where people...conference paper 2022

Pascoletti, Giulia (author), Huysmans, T. (author), Conti, Paolo (author), Zanetti, Elisabetta M. (author)In this work a new approach for the creation of Articulated Total Body (ATB) models for person-specific multi-body simulations is presented, with the main aim of overcoming limitations related to classical multi-ellipsoids ATB models, based on regression equations having only the weight and the height of the subject as input. The new...conference paper 2022

Baioumy, Mohamed (author), Pezzato, C. (author), Hernández, Carlos (author), Hawes, Nick (author), Ferrari, Riccardo M.G. (author)This work presents a fault-tolerant control scheme for sensory faults in robotic manipulators based on active inference. In the majority of existing schemes a binary decision of whether a sensor is healthy (functional) or faulty is made based on measured data. The decision boundary is called a threshold and it is usually deterministic....conference paper 2022

Poenaru-Olaru, L. (author), Redi, Judith (author), Hovanesyan, Artur (author), Wang, H. (author)Small and medium enterprises (SME) are crucial for economy and have a higher exposure rate to default than large corporates. In this work, we address the problem of predicting the default of an SME. Default prediction models typically only consider the previous financial situation of each analysed company. Thus, they do not take into account...conference paper 2022

Verheyen, Jan K.N. (author), Dupeyroux, J.J.G. (author), de Croon, G.C.H.E. (author)Insects have—over millions of years of evolution—perfected many of the systems that roboticists aim to achieve; they can swiftly and robustly navigate through different environments under various conditions while at the same time being highly energy efficient. To reach this level of performance and efficiency, one might want to look at and...conference paper 2022

Kapppers, Astrid M.L. (author), Plaisier, M.A. (author)In this paper, we present an overview of parameters that are of relevance for the perception of vibrotactile patterns on the back. These patterns are delivered via varying numbers of vibration motors fixed to the back rest of a chair, vests or belts. We present recent findings from the literature about vibrotactile anisotropy, timing, spacing...conference paper 2022

Dikken, O.D.F. (author), Limbu, B.H. (author), Specht, M.M. (author)It takes considerable time, experience, and direct assistance from teachers to become a skilled writer. Handwriting fluency is one of the predictors of writing quality among students. However, students do not receive enough teacher supervision as a beginner to develop handwriting fluency in a proper manner. The ``Calligraphy tutor'' presented in...conference paper 2022

Lemke, Florian (author), Janssen, M.F.W.H.A. (author), Draheim, Dirk (author)The need for standardized and visualized performance monitoring on a wide range of topics has become apparent in recent years. In the public sector, there has been an increase in the number of dashboards to create transparency into the progress. Yet, the design of dashboards encounters many challenges ranging from technical to social. The goal...conference paper 2022

A specific target is the reduction of the amount of concrete used. Funicular structures that base their strength on their structurally-informed geometry allow for material efficiency. However, a...conference paper 2022

Murgia, Emiliana (author), Landoni, Monica (author), Huibers, Theo (author), Pera, M.S. (author)In this manuscript, we discuss the findings from an introductory survey conducted with more than 50 teachers in Italy. We inquired about teachers’ opinions of educational technology used in the classroom, in particular search tools. Qualitative and quantitative data inferred from collected responses provide us with a multifaceted picture of...conference paper 2022

Dell'Anna, D. (author), Alechina, Natasha (author), Dalpiaz, Fabiano (author), Dastani, Mehdi (author), Löffler, Maarten (author), Logan, Brian (author)Norms have been widely proposed as a way of coordinating and controlling the activities of agents in a multi-agent system (MAS). A norm specifies the behaviour an agent should follow in order to achieve the objective of the MAS. However, designing norms to achieve a particular system objective can be difficult, particularly when there is no...conference paper 2022
