About This PhD Project

Project Description

Summary

Photoplethysmography (PPG) is widely used in wearables to record heart activity. Analysis of interbeat-intervals (IBI) inferred from PPG recordings provide a powerful means of assessing the activities of the autonomic nervous system (ANS) by observing the interplay between the sympathetic and parasympathetic contributions. Consumer health research has notably used wearable data for sleep, stress, recovery and more recently pain assessment. Leading approaches to evaluate these metrics involve selecting a set of manually engineered features from the IBI time series - e.g resting heart rate and pulse rate variability (PRV) - and feeding them to a small neural network.

Research in clinical diagnosis of cardiac diseases has established that end-to-end deep learning approaches perform best at classifying a wide range of heart arrhythmias from electrocardiography (ECG). We thus expect the use of end-to-end deep learning to achieve significant improvements in sleep, stress, recovery and pain assessment over present approaches. More generally we research how to unify these metrics into a more general measure of well-being.

The aim of this project is to design and build a unified end-to-end deep learning model that is capable of handling raw physiological data to assess and predict our well-being. You will work with a large set of physiological data (IBI and motion data) combined with rich context information and insights into our customers’ well-being inferred from our application. More specifically as part as your research you will study the following topics:

Semi-supervised end-to-end deep learning algorithms that can handle noisy (i.e. physiological and measurement artifacts), sparse (i.e. missing data and unreliable data points) and partially labeled IBI and motion time series collected by wearables
Multi-stage (e.g. global and individual) learning phases to optimize accuracy given the wide inter-patient variability
Comparison of learned feature representations of IBI data with standard PRV metrics
Assessment and prediction of well-being
