Proceedings ArticleDOI
Deep learning Parkinson's from smartphone data
Cosmin Stamate,George D. Magoulas,Stefan Kueppers,Effrosyni Nomikou,Ioannis Daskalopoulos,Marco U. Luchini,Theano Moussouri,George Roussos +7 more
TL;DR: How the cloudUPDRS system addresses two key challenges towards meeting essential consistency and efficiency requirements is discussed, including how to reduce test duration from approximately 25 minutes typically required by an experienced patient, to below 4 minutes, a threshold identified as critical to obtain significant improvements in clinical compliance.
Journal ArticleDOI
The cloudUPDRS app: A medical device for the clinical assessment of Parkinson's Disease
Cosmin Stamate,George D. Magoulas,Stefan Kueppers,Effrosyni Nomikou,Ioannis Daskalopoulos,Ashwani Jha,Joan Saez Pons,John C. Rothwell,Marco U. Luchini,Theano Moussouri,Marco Iannone,George Roussos +11 more
TL;DR: The cloudUPDRS system addresses two key challenges towards meeting essential consistency and efficiency requirements, namely: how to ensure high-quality data collection and how to reduce test duration from approximately 25 min typically required by an experienced patient, to below 4 min, a threshold identified as critical to obtain significant improvements in clinical compliance.
Journal ArticleDOI
A Vision Transformer Model for Convolution-Free Multilabel Classification of Satellite Imagery in Deforestation Monitoring
Maria Kaselimi,Athanasios Voulodimos,Ioannis Daskalopoulos,Nikolaos Doulamis,Anastasios Doulamis +4 more
TL;DR: In this paper , a multilabel vision transformer model, ForestViT, was proposed to capture the various relevant land uses from satellite images, which leverages the benefits of the self-attention mechanism, obviating any convolution operations involved in commonly used deep learning models utilized for deforestation detection.
Journal ArticleDOI
The CloudUPDRS smartphone software in Parkinson's study: cross-validation against blinded human raters.
Ashwani Jha,Elisa Menozzi,Elisa Menozzi,Rebecca Oyekan,Anna Latorre,Eoin Mulroy,Sebastian Schreglmann,Cosmin Stamate,Ioannis Daskalopoulos,Stefan Kueppers,Marco U. Luchini,John C. Rothwell,George Roussos,Kailash P. Bhatia +13 more
TL;DR: Smartphone-based measures of motor severity have predictive value at the subject level and future studies should mitigate against subjective and feature selection biases and assess performance across a range of motor features as part of a broader strategy to avoid overly optimistic performance estimates.
Journal ArticleDOI
Sensor Cube: A Modular, Ultra-Compact, Power-Aware Platform for Sensor Networks
Hamadoun Diall,Kishore Raja,Ioannis Daskalopoulos,Stephen Hailes,George Roussos,Tom Torfs,Chris Van Hoof +6 more
TL;DR: This paper presents the experience with the Sensor Cube platform and, in particular, the implications of its ultra-compact design on system performance, specifically as it relates to the characteristics and limitations of the radio unit.
