Machine Learning-Aided Monitoring and Prediction of Respiratory and Neurodegenerative Diseases Using Wearables
Skibińska, Justyna ; Esposito, Anna (referee) ; Faundez-Zanuy, Marcos (referee) ; Hošek, Jiří (advisor)
This thesis focuses on wearables for health status monitoring, covering applications aimed at emergency solutions to the COVID-19 pandemic and aging society. The methods of ambient assisted living (AAL) are presented for the neurodegenerative disease Parkinson's disease (PD), facilitating 'aging in place' thanks to machine learning and around wearables - solutions of mHealth. Furthermore, the approaches using machine learning and wearables are discussed for early-stage COVID-19 detection. Firstly, a publicly available dataset containing COVID-19, influenza, and healthy control data was reused for research purposes. The solution presented in this thesis is considering the classification problem and outperformed the state-of-the-art methods, whereas the original paper introduced just anomaly detection. The proposed model in the thesis for early detection of COVID-19 achieved 78 % for the k-NN classifier. Moreover, a second dataset available on request was utilized for recognition between COVID-19 cases and two types of influenza. The scrutinisation in the form of the classification between the COVID-19 and Influensa groups is proposed as the extension to the research presented in the original paper. The accuracy of the distinction between COVID-19 cases and influenza in the middle of the pandemic was equal to 73 % thanks to the k-NN. Furthermore, the contribution as the classification model of two aforementioned combined datasets was provided, and COVID-19 cases were able to be distinguished from healthy controls with 73 % accuracy thanks to XGBoost algorithm. The undeniable advantage of the illustrated approaches is taking into consideration the incubation period and contagiousness of the disease. In addition, some solutions for the detection of the aforementioned aging society phenomenon are presented. This study explores the possibility of fusing computerised analysis of hypomimia and hypokinetic dysarthria for the spectrum of Czech speech exercises. The introduced dataset is unique in this field because of its diversity and myriad of speech exercises. The aim is to introduce a new techniques of PD diagnosis that could be easily integrated into mHealth systems. A classifier based on XGBoost was used, and SHAP values were used to ensure interpretability. The presented interpretability allows for the identification of clinically valuable biomarkers. Moreover, the fusion of video and audio modalities increased the balanced accuracy to 83 %. This methodology pointed out the most indicative speech exercise – tongue twister from the clinical point of view. Furthermore, this work belongs to just a few studies which tackle the subject of utilising multimodality for PD and this approach was profitable in contrast with a single modality. Another study, presented in this thesis, investigated the possibility of detecting Parkinson's disease by observing changes in emotion expression during difficult-to-pronounce speech exercises. The obtained model with XGBoost achieved 69 % accuracy for a tongue twister. The usage of facial features, emotion recognition, and computational analysis of tongue twister was proved to be successful in PD detection, which is the key novelty and contribution of this study. Additionally, the unique overview of potential methodologies suitable for the detection of PD based on sleep disorders was depicted.

Saafi, Salwa ; Bečvář, Zdeněk (referee) ; Tölli, Antti (referee) ; Hošek, Jiří (advisor)
Smartphones are no longer the only portable devices changing the lives and daily routines of today’s digitally connected consumers. Smart glasses, watches, headsets, cameras, bands, trackers, monitors, and scanners are all examples of hands-free inherently mobile wearable devices that enable the emerging consumer and industrial applications. Similarly to customers who are ready to embrace life-changing experiences with new devices, companies and industries are also employing smart helpers and intelligent assistant systems to improve the efficiency of their automated processes and the productivity and safety of their workers. Not limited to the employment of smart helpers, the industrial digital transformation relies heavily on the deployment of communication infrastructures that utilize efficient cellular technologies to meet the dissimilar requirements of industrial applications. Motivated by these intelligent assistant systems and communication technologies, this dissertation focuses on the role of wearable technology and cellular connectivity in enabling the automation of vertical domains. Aiming to address the current technology gap behind cellular-enabled industrial wearables, the present work is dedicated to assessing the applicability of cellular connectivity to industrial wearables and developing efficient access and backhaul solutions for the support of the requirements of emerging industrial applications. The following outline of this dissertation is built around the main objectives as highlighted above and presents the main outcomes of this work, which include (i) a concise technology review capturing the evolution of the recent solutions proposed by the 3rd Generation Partnership Project (3GPP) for wearable devices and communications, (ii) an introduction to novel categories of industrial wearable applications with mid-end requirements that fall in-between the two extremes of high-end and low-end Fifth-Generation (5G) service classes, (iii) an assessment of the applicability of the emerging Reduced-Capability New Radio (NR RedCap) technology to the newly introduced wearable applications, (iv) an extension of the RedCap wearable communications with Device-to-Device (D2D) and Supplementary Uplink (SUL) capabilities for enhanced access network performance, (v) a cost-efficient backhaul selection solution based on Markov Decision Processes (MDPs) for time-sensitive wearable applications in an integrated terrestrial and non-terrestrial communication scenario, and (vi) a data-driven Artificial Intelligence (AI)-aided approach for the management of complex industrial networks with dissimilar device capabilities, communication solutions, and application requirements. A set of simulation and analytical models is developed to assess the relevant key performance indicators as part of the above contributions. Beyond indicating the need for technology improvement demanded by the efficient integration of wearable devices into cellular networks and the satisfaction of industrial application requirements, the numerical results reported in this dissertation confirm the network performance enhancements achieved by the access and backhaul solutions contributed in this work.

The possibility of measuring the intensity of physical activity based on the number of steps and heart rate data in adults, school and preschool children
Jarco, Michal ; Buchtelová, Aneta (advisor) ; Musálek, Martin (referee)
The number of people suffering from overweight or obesity is growing worldwide. One of the most important factors contributing to weight gain is the lack of exercise, which is nowadays caused mainly by a sedentary lifestyle. Exercise is therefore very important for our health and in children it also significantly contributes to the proper development of their cognitive functions. This thesis is focused on the possibility of using data about total number of steps for a certain time unit (per minute or throughout the day) to classify the intensity of physical activity (especially moderate and vigorous) it also marginally deals with the possibility of evaluating the intensity of physical activity using heart rate data. According to internationally recognized standards, an adult should spend at least 30 minutes (60 minutes is recommended for children) a day in moderate intensity physical activity, or 15 minutes (30 minutes for children) in vigorous intensity physical activity. Many studies focused on adults agreed that the cadence of around 90-110 steps per minute is optimal for achieving moderate intensity of physical activity, but the height, age and gender of individuals also play an important role. For children, this value is around 120 steps per minute, but age is much more important than gender....
