PhD Studentship: Machine Learning for Probabilistic Modelling of Non-equilibrium Time Series Beyond the Markovian Paradigm SCI3042

Closing date: Open Until Filled

Funding amount: Full tuition fee waiver pa (Home Students only) and stipend at above UKRI rates pa (currently at £20,780 for 2025/26 academic year, increasing in line with inflation). Research training and support grant (RTSG) of £3,000 per year. Funding is available for 4 years.

Closes: Open until position filled

The overarching aim of this project is to find synergies between methods and ideas of modern machine learning and of statistical mechanics for the study of stochastic dynamics with application to the analysis of time series. In particular, the project will examine and develop methods that go beyond the Markovian paradigm. It will consider a range of time series data, focusing on those that show challenging properties of uncertainty, irregularity and mixed-modality. It will examine a range of models and techniques that go beyond Markovian approaches, including state-space models, tensor networks, and machine learning frameworks such as recurrent neural networks and transformers. Models and datasets will be studied and benchmarked in key tasks relating to both prediction/forecasting and anomaly detection. Comparison with known analytic methods and established Markov models will be made wherever possible. Expected outcomes include a unified non-Markovian framework for time series analysis, a suite of relevant datasets, and large-scale statistical studies comparing different methods. The successful candidate will be jointly supervised by:

Dr Edward Gillman (www.nottingham.ac.uk/physics/people/edward.gillman)

and

Professor Juan P. Garrahan (www.nottingham.ac.uk/physics/people/juan.garrahan)

Supervisors: Dr. Edward Gillman, Professor Juan P. Garrahan
