Chiscop, I. (author), Soro, F. (author), Smith, P. (author)Threat hunting and malware prediction are critical activities to ensure network and system security. These tasks are difficult due to increasing numbers of sophisticated malware families. Automatically detecting anomalous Domain Name System (DNS) queries in operational traffic facilitates the detection of new malware infections, significantly...conference paper 2022

He, Y. (author), Coutino, M. (author), Isufi, E. (author), Leus, G. (author)In this work, we focus on partitioning dynamic graphs with two types of nodes (bi-colored), though not necessarily bipartite graphs. They commonly appear in communication network applications, e.g., one color being base stations, the other users, and the dynamic process being the varying connection status between base stations and moving users....conference paper 2022

Doulgerakis, E. (author), Laarhoven, T. (author), de Weger, B. (author)The main idea behind lattice sieving algorithms is to reduce a sufficiently large number of lattice vectors with each other so that a set of short enough vectors is obtained. It is therefore natural to study vectors which cannot be reduced. In this work we give a concrete definition of an irreducible vector and study the properties of the set of...article 2022

Albers, N. (author), Neerincx, M.A. (author), Brinkman, W.P. (author)Behavior change applications often assign their users activities such as tracking the number of smoked cigarettes or planning a running route. To help a user complete these activities, an application can persuade them in many ways. For example, it may help the user create a plan or mention the experience of peers. Intuitively, the application...article 2022

Rasheed, M.B. (author), Rodriguez Moreno, M.D. (author)This paper considers the time of use (TOU) pricing scheme to propose a consumer aware pricing policy (CAPP), where each customer receives a separate electricity pricing signal. These pricing signals are obtained based on individualized load demand patterns to optimally manage the flexible load demand. The main objective of CAPP is to reduce the...article 2022

Burghouts, G.J. (author), Huizinga, W. (author)Visual Question Answering (VQA) is a very interesting tech nique to answer natural language questions about an image. Recent methods have focused on incorporating knowledge into an improved VQA model, by augmenting the training set, representing scene graphs, or including reasoning. We also leverage knowledge to make VQA more robust. Yet we take...conference paper 2022

Hayes, P. (author), van de Poel, I. (author), Steen, M. (author)Algorithms and AI tools are becoming increasingly influential artefacts in commercial and governance contexts. Algorithms and AI tools are not value neutral; to some extent they must be rendered knowable and known as objects, and in their implementation and deployment, to see clearly and understand their implications for moral values, and what...article 2022

Steen, M. (author), van Diggelen, J. (author), Timan, T. (author)We used two ideas from cybernetics—the sociotechnical system and the feedback loop—to explore ways to deal with some current challenges in the design and application of AI systems, e.g., in Human-Machine Teaming and Algorithmic Decision Making. As thought experiments, we envisioned two ‘cybernetic’ systems. Our goal is to explore the usefulness...conference paper 2022

Eledlebi, K. (author), Ruta, D. (author), Hildmann, H. (author), Saffre, F. (author), al Hammadi, Y. (author), Isakovic, A.F. (author)When deploying a wireless sensor network (WSN) identifying optimal locations for the nodes is challenging, especially so if the environment is either (i) unknown or (ii) obstacle-rich. We proposes BISON (Bio-Inspired Self-Organizing Network), a variant of the Voronoi algorithm to address this challenge. Among the features of the approach are the...article 2022

de Gijsel, S.L. (author), Vijn, A.R.P.J. (author), Tan, R.G. (author)This paper proposes an algorithm to localize a magnetic dipole using a limited number of noisy measurements from magnetic field sensors. The algorithm is based on the theory of compressed sensing, and exploits the sparseness of the magnetic dipole in space. Beforehand, a basis consisting of magnetic dipole fields belonging to individual dipoles...article 2022

However, the adversarial nature...conference paper 2022

In particular, we assume that every party knows specific features of an overlapping set of people. Using a secure implementation of an advanced hidden set intersection protocol and a...conference paper 2021

Bornet, A. (author), Doerig, A. (author), Herzog, M.H. (author), Francis, G. (author), van der Burg, E. (author)In crowding, perception of a target deteriorates in the presence of nearby flankers. Traditionally, it is thought that visual crowding obeys Bouma's law, i.e., all elements within a certain distance interfere with the target, and that adding more elements always leads to stronger crowding. Crowding is predominantly studied using sparse displays ...article 2021
