Supporting the process of learning and teaching process models
(2020-03-30)
Article
Restricted access - publisher's policyThe creation of a process model faces the challenge of constructing a syntactically correct entity which accurately reflects the semantics of the reality, and is understandable. This paper proposes a framework called ... -
Synthetic dataset generation with itemset-based generative models
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThis paper proposes three different data generators, tailored to transactional datasets, based on existing itemset-based generative models. All these generators are intuitive and easy to implement and show satisfactory ... -
Characterizing transactional databases for frequent itemset mining
(CEUR-WS.org, 2019)
Conference report
Open AccessThis paper presents a study of the characteristics of transactional databases used in frequent itemset mining. Such characterizations have typically been used to benchmark and understand the data mining algorithms working ... -
Follower behavior under stress in immersive VR
(2020-03-06)
Article
Restricted access - publisher's policyUnderstanding human decision making is a key requirement to improve crowd simulation models so that they can better mimic real human behavior. It is often difficult to study human decision making during dangerous situations ... -
A scalable approach to T2-MRI colon segmentation
(2020-07-01)
Article
Restricted access - publisher's policyThe study of the colonic volume is a procedure with strong relevance to gastroenterologists. Depending on the clinical protocols, the volume analysis has to be performed on MRI of the unprepared colon without contrast ... -
Effective visualization of sparse image-to-image correspondences
(European Association for Computer Graphics (Eurographics), 2020)
Conference report
Open AccessFinding robust correspondences between images is a crucial step in photogrammetry applications. The traditional approach to visualize sparse matches between two images is to place them side-by-side and draw link segments ... -
A Tool for N-way analysis of programming exercises
(European Association for Computer Graphics (Eurographics), 2020)
Conference report
Open AccessProgramming exercises are a corner stone in Computer Science courses. If used properly, these exercises provide valuable feedback both to students and instructors. Unfortunately, the assessment of student submissions through ... -
A semantic model to fight social exclusion
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessThis work presents a semantic model meant to help with the identification and prediction of individuals at risk of social exclusion. The model is based on the self-sufficiency matrix, a tool that evaluates a person's ... -
Co-occurrence patterns in diagnostic data
(Wiley (John Wiley & Sons), 2020-04-12)
Article
Open AccessWe demonstrate how graph decomposition techniques can be employed for the visualization of hierarchical co-occurrence patterns between medical data items. Our research is based on Gaifman graphs (a mathematical concept ... -
Multi-view image fusion
(2019)
Conference report
Open AccessWe present an end-to-end learned system for fusing multiple misaligned photographs of the same scene into a chosen target view. We demonstrate three use cases: 1) color transfer for inferring color for a monochrome view, ... -
A software service supporting software quality forecasting
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessSoftware repositories such as source control, defect tracking systems and project management tools, are used to support the progress of software projects. The exploitation of such data with techniques like forecasting is ... -
From process models to chatbots
(Springer, 2019)
Conference report
Open AccessThe effect of digital transformation in organizations needs to go beyond automation, so that human capabilities are also augmented. A possibility in this direction is to make formal representations of processes more ...
