Sioutas, S. (author), Stuijk, S. (author), Basten, T. (author), Somers, L. (author), Corporaal, H. (author)Tensor Cores (TCUs) are specialized units first introduced by NVIDIA in the Volta microarchitecture in order to accelerate matrix multiplications for deep learning and linear algebra workloads. While these units have proved to be capable of providing significant speedups for specific applications, their programmability remains difficult for the...conference paper 2020

(author)(m, k)-firm real-time tasks require meeting the deadline of at least m jobs out of any k consecutive jobs. When compared to hard real-time tasks, (m, k)-firm tasks open up the possibility of tighter resource-dimensioning in implementations. Firmness analysis verifies the satisfaction of (m, k)-firmness conditions. Scheduling policies under which...conference paper 2020

Sioutas, S. (author), Stuijk, S. (author), Basten, T. (author), Corporaal, H. (author), Somers, L. (author)The Halide DSL and compiler have enabled high-performance code generation for image processing pipelines targeting heterogeneous architectures through the separation of algorithmic description and optimization schedule. However, automatic schedule generation is currently only possible for multi-core CPU architectures. As a result, expert...conference paper 2020

van Diggelen, J. (author), Johnson, M. (author)This paper introduces the concept of team design patterns and proposes an intuitive graphical language for describing the design choices that influence how intelligent systems (e.g. artificial intelligence, robotics, etc.) collaborate with humans. We build on the notion of design patterns and characterize important dimensions within human-agent...conference paper 2019

Schuts, M. (author), Hooman, J. (author), Tielemans, P. (author)Software departments of companies that exist for several decades often have to deal with legacy models. Important business assets have been modelled with tools that are no longer preferred within the company. Manually remodelling these models with a new tool would be too costly. In this paper, we describe an approach to migrate from Rhapsody...conference paper 2018

Verriet, J. (author), Dankers, R. (author), Somers, L. (author)Performance is a critical system property of any system, in particular of data-intensive systems, such as image processing systems. We describe a performance engineering method for families of data-intensive systems that is both simple and accurate; the performance of new family members is predicted using models of existing family members. The...conference paper 2018

(author)We examined physiological responses to behavior of an Adaptive Cruise Control (ACC) system during real driving. ACC is an example of automating a task that used to be performed by the user. In order to preserve the link between the user and an automated system such that they work together optimally, physiological signals reflecting mental state...conference paper 2017

We here propose to predict head rotation on the basis of brain signals in order to improve images presented in a Head Mounted Display (HMD)....conference paper 2017

(author), Neerincx, M.A. (author)This paper describes the design and development of an embodied conversational agent (ECA) that provides a social interface for older adults. Following a user-centred design approach, we implemented a multimodal agent consisting of a virtual character and a robot. This so-called "bi-bodied conversational agent for elderly" was iteratively refined...conference paper 2016

One of the most challenging question types in this field is counting, such as How many sheep are in this picture. In this paper, we focus on counting questions and improve upon the state-of-the-art method DPPnet. We train concept...conference paper 2016
