Obstacles and challenges identified by practitioners of non-formal science learning activities in Europe
(Peer reviewed; Journal article, 2022)Despite the increasing demand for non-formal science learning activities, few studies report on practitioners' perspectives and experiences with designing and implementing such activities worldwide. This paper focuses on ... -
OCAP: On-device Class-Aware Pruning for personalized edge DNN models
(Journal article; Peer reviewed, 2023)In this paper, we propose a new on-device class-aware pruning method for edge systems, namely OCAP. The motivation behind is that Deep Neural Network (DNN) models are usually trained with a large dataset so that they can ... -
Occam's razor for big data? On detecting quality in large unstructured datasets
(Journal article; Peer reviewed, 2019)Detecting quality in large unstructured datasets requires capacities far beyond the limits of human perception and communicability and, as a result, there is an emerging trend towards increasingly complex analytic solutions ... -
OctoUML: an environment for exploratory and collaborative software design
(Journal article; Peer reviewed, 2017)Software architects seek efficient support for planningand designing models at multiple levels of abstraction andfrom different perspectives. For this it is desirable that softwaredesign tools support both informal and ... -
Odds fluctuations and potential trading profit for popular betting events
