Dr. Hu has received several awards and recognitions for his research, including: the Best Track Paper Award at the IISE Annual Conference & Expo in 2019; the ASME Design Automation Young Investigator Award in 2018; the Highly Cited Research Paper 2012-2013 in the Journal of Applied Energy in 2015; the Star of Excellence Individual Award at Medtronic in 2014; and the Best Paper Awards at the ASME Design Automation Conference and the IEEE International Conference on Prognostics and Health Management in 2013 and 2012, respectively.
Abstract
Over the past decade, a large and diverse set of battery prognostics techniques have been developed for forecasting the capacity and predicting the remaining useful life of lithium-ion batteries. The past two years has seen increasing research efforts developing and validating machine learning algorithms and models for early life prediction. The idea is to predict battery cycle life using early-cycle data where battery cells show negligible capacity degradation. This tutorial will review past and ongoing research studies on battery capacity forecasting and early life prediction and discuss the long-term testing and methodology development efforts led by a team of researchers at Iowa State University. |

Machine Learning for the Next Generation of Health Informatics IDr. Yvonne Lu
Biography
Dr. Lu obtained her DPhil at the Industrial Informatics and Signal Processing Group, in the Department of Engineering at the University of Sussex in 2008. During her doctoral study, she developed a commercial iris-identification system for use on mobile phones, which led to a patent and her work being presented at the House of Commons in 2007. She then worked on breast cancer research at the University of Sussex and the John Radcliffe Hospital, Oxford, followed by research into diabetic retinopathy at the University of Liverpool and the Royal Liverpool Hospital. She joined the Institute of Biomedical Engineering at the University of Oxford in 2018. Her current research is focussed on the development of machine learning methods for robustly tracking patient condition using home-monitoring systems for chronic disease. In 2019, she was awarded a Daphne Jackson Trust / Royal Academy of Engineering Fellowship, which supports her as an independent investigator focused on technology for maternal and child health.
Abstract
Ever-increasing qualities and quantities of data are routinely collected across a wide range of applications that offer a rich source of information. The developments in wearable sensors, smart home technologies, and the Internet of Things provide industries with opportunities to monitor patients’ health and machines’ health with the power of AI without significant disruption to their everyday activities. Analysing the large dataset, sometimes real-time collected data poses emerging challenges in data science as the data can have substantial artefacts; the dataset might be highly imbalanced and incomplete, and might contain high levels of variability. Moreover, data labelling can be expensive and time-consuming if there is an insufficient number of high-quality labels. In this tutorial, we will introduce several machine learning techniques to tackle these issues and provide robust solutions. Innovations arising from clinical science will be used to demonstrate how deep learning and probabilistic can facilitate rapid clinical intervention, transform a hospital-only treatment pathway into a cost-effective, home-based, combined alternative, and thus improve the overall quality of patient healthcare. The machine learning methods presented in these case studies can be implemented in other industrial domains that face similar challenges, such as tracking the health condition of machinery and predicting machine deterioration for maintenance scheduling. |

Machine Learning for the Next Generation of Health Informatics IIDr. Samaneh Kouchaki
Biography
Dr. Kouchaki joined CVSSP in July 2020 to lead research and teaching in machine learning for health and dementia care in collaboration with the UK Dementia Research Institute (UK DRI) Care Research & Technology Centre (a joint initiative between CVSSP, the Surrey Sleep Research Centre and Department of Mathematics at Surrey, and Imperial College London). Dr. Kouchaki previously spent three years as a postdoctoral researcher within the Institute of Biomedical Engineering at the University of Oxford. She was the senior machine learning researcher for the ‘100,000 Genomes Project for Tuberculosis’, an international consortium involving the Centres for Disease Control of most major nations (including the USA, UK and China), jointly funded by the Gates Foundation and the Wellcome Trust. Her research focus was on the prediction of antibiotic resistance in pathogens such as those that cause tuberculosis. Prior to this, she was at the University of Manchester within the Division of Evolutionary and Genomic Sciences where she was funded by the EU Horizon 2020 Virogenesis project, working on next-generation DNA sequencing using signal and image processing techniques coupled with unsupervised machine learning. Dr. Kouchaki obtained her PhD in Computer Science at Surrey in 2015. Hery PhD focused on developing novel multi-way techniques for source separation with application to biomedical signals.

Abstract
Mobility is a core technology with internet of things and artificial intelligence for the 4th industrial revolution. The mobility is also effective in the research field of prognostics and health management (PHM) in the sense that this technology not only provides an easy way to approach any facility of interest, but also replaces human’s duty in a dangerous environment for condition monitoring and fault detections. This tutorial presents the mobility toward PHM with smart inspection systems for overhung and underground power transmission lines. Inspection of power transmission lines at severe environments would be a good example to demonstrate effectiveness of mobility because power transmission lines are wide-spread, located at a variety of regions, and suffer from severe environments. A field demonstration of these platforms confirm inherent advantages of the mobility. |

Abstract
Digital twin is a core technology to prognostic and health management (PHM). Model driven digital twin may provide more information of physical assets than data driven digital twin, but it requires much more computational burden. To handle this issue, many CAE software with twin builder (e.g. ANSYS, Siemens, etc) include various reduced-order modeling (ROM) techniques for linear and nonlinear systems. The tutorial presents an effective model driven digital twin framework of vibro-acoustic interaction problem with multiphysics model reduction. A real-time virtual sensor of fluid-filled pipe implemented by the framework will be also introduced. The virtual sensor can estimate the unmeasured time transient responses of a vibro-acoustic structure in real time. The tutorial includes a theoretically review of vibro-acoustic model reduction with its example codes. |
