A query language perspective on graph learning Universiteit Antwerpen
A key component of graph and relational learning methods is the computation of vector representations of the input graphs or relations. The starting point of this tutorial is that we model this computation as queries, mapping relational objects into the realm of real vector spaces. We then revisit recent works in the machine learning community on the expressive power of graph learning methods from this unifying query language perspective. Here, ...
Digital-twin co-evolution using continuous validation Universiteit Antwerpen
In a continuous improvement design-operation continuum, model-based digital twins are used throughout. However, to make correct decisions, the model must remain a valid representation of the real-world system it twins. If a system only performs its cyclic operation, it may fail to collect the right data to detect when the model invalidation occurs. To tackle this challenge, we propose a workflow that works with continuous validation, in which a ...
A performance-based acoustical design strategy for centralized air distribution networks Universiteit Antwerpen
HVAC engineers are frequently challenged to design centralized air distribution systems with a high standard of performance considering comfort, energy efficiency, and indoor environmental quality. However, conventional design processes of centralized air distribution systems rely on rules of thumb and engineers’ experience, resulting in workable designs but not necessarily optimal in terms of performance and cost. One major challenge of this ...
Towards hypersemitoric systems Universiteit Antwerpen
This survey gives a short and comprehensive introduction to a class of finite dimensional integrable systems known as hypersemitoric systems, recently introduced by Hohloch and Palmer in connection with the solution of the problem how to extend Hamiltonian circle actions on symplectic 4-manifolds to integrable systems with ‘nice’ singularities. The quadratic spherical pendulum, the Euler and Lagrangne tops (for generic values of the Casimirs), ...
Human motion prediction on the IKEA-ASM dataset Universiteit Antwerpen
Motion prediction of the human pose estimates future poses based on the preceding poses. It is a stepping stone toward industrial applications, like human-robot interactions and ergonomy indicators. The goal is to minimize the error in predicted joint positions on the IKEA-ASM dataset which resembles assembly use cases with a high diversity of execution and background of the same action class. In this paper, we use the STS- GCN model to tackle ...
A new research protocol for using system maps in systemic design research Universiteit Antwerpen
System maps are established tools in design practice and education as well as non-design research, both as a process and an outcome of systemic analysis and synthesis. Applying causal loop diagrams (CLD's) in (systemic) design research could be of great value to tackle the growing societal complexity. At this moment there is, however, no clear research protocol to include the rich data necessary for systemic research and ensure a scientifically ...
HyLECA Universiteit Antwerpen
We present HyLECA, an open-source framework designed for the development of long-term engaging controlled conversational agents. HyLECA’s dialogue manager employs a hybrid architecture, combining rule-based methods for controlled dialogue flows with retrieval-based and generation-based approaches to enhance the utterance variability and flexibility. The motivation behind HyLECA lies in enhancing user engagement and enjoyment in task-oriented ...
Model-driven Quantum Federated Learning (QFL) Universiteit Antwerpen
Recently, several studies have proposed frameworks for Quantum Federated Learning (QFL). For instance, the Google TensorFlow Quantum (TFQ) and TensorFlow Federated (TFF) libraries have been deployed for realizing QFL. However, developers, in the main, are not as yet familiar with Quantum Computing (QC) libraries and frameworks. A Domain-Specific Modeling Language (DSML) that provides an abstraction layer over the underlying QC and Federated ...
How to turn your camera into a perfect pinhole model Universiteit Antwerpen
Camera calibration is a first and fundamental step in various computer vision applications. Despite being an active field of research, Zhang’s method remains widely used for camera calibration due to its implementation in popular toolboxes like MATLAB and OpenCV. However, this method initially assumes a pinhole model with oversimplified distortion models. In this work, we propose a novel approach that involves a pre-processing step to remove ...
