This research will develop methods to infer the dimensionality of a dynamical system automatically, by adapting dimensionality reduction methods to high-dimensional time-series feature spaces.
Finding simple principles that can explain the complexity of the world around us often relies on finding lower-dimensional representations (or manifolds) of high-dimensional data. The complex dynamics of many real-world systems can be well-approximated by the variation of only a handful of parameters. Successful inference of these parameters in a data-driven way would be a major advance with an impact felt across science and industry. For example, if we understand the hidden patterns underlying variability across patients with a given disease, doctors could learn what minimal set of tests to run on their patients in order to recommend the optimal treatment. In this project, the student will apply a new highly comparative analysis framework, hctsa, to time-series datasets to develop new data-driven methods to automatically infer the parametric dimensionality of a range of physical (and other real-world) systems.
Excellent facilities are available to carry out all aspects of the work, including access to computing resources and large collections of time-series data. There is much flexibility to adjust the specific project to the interests of the student, who should have a strong interest in data science (with a quantitative background in e.g., physics, mathematics, statistics, engineering, or computer science). Top-up funding is available for the highest quality of applicants, with additional funding available to support travel to present research results at national and international conferences (or to visit collaborators, e.g., at Monash University or Imperial College London).
