About the Project

Time series classification (TSC) involves building predictive models for problems where the attributes are ordered. So, for example, we may want to predict whether a patient is healthy or not based on their heartbeat. UEA has been at the forefront in developing algorithms for this type of problem [1,2,3]. TSC assumes that each observation is independent (e.g. a separate patient). An alternative common scenario is when we have a time series where readings are continuously taken, and we wish to detect when a specific event occurs. We may, for example, want to detect when a person falls over based on a motion sensor that is continuously collecting data. There are a range of techniques for doing this that are closely related to classification algorithms. The student will work in a vibrant research group to design algorithms within open source code frameworks [4] and evaluate them on a range of real world problems. There will be opportunities to work with our collaborators across the world, including researchers at the Alan Turing Institute, the University of California, USA and Monash University, Australia.
