From: Jared Tanner tanner@maths.ox.ac.uk
Date: October 28, 2024
Subject: Postdoctoral Positions, Mathematical and Computational Foundations of AI, University of Oxford, UK

We invite applications for four Postdoctoral Research Associates
(PDRA) to join the EPSRC Hub on the Mathematical and Computational
Foundations of Artificial Intelligence. One PDRA will be recruited for
each of the following four research themes: Learning with Structured &
Geometric Models, Low Effective- dimensional Learning Models, Implicit
Regularization, and Reinforcement Learning through Stochastic
Control. A brief description of each these is as follows (additional
details are in the further particulars):

Learning with Structured and Geometric Models. We will apply tools
from manifold learning and Riemannian optimisation to leverage the
underlying manifold structure for better training and novel network
designs.

Low Effective-dimensional Learning Models. We will extend
foundational theory of how large ML systems can be regularised to have
dramatically fewer trainable parameters without sacrificing accuracy
by analysing the use of low- dimensional building blocks

Implicit Regularization. We aim to develop mathematical understanding
of implicit regularisation properties in deep neural networks to guide
the development of algorithmic paradigms aimed at combining
statistical optimality with computational efficiency.

Reinforcement Learning through Stochastic Control. We will develop
methods from stochastic control, which will provide a mathematically
grounded approach that has a well-posed continuous-time limit (as
opposed to traditional RL methods that are inherently discrete and do
not scale favourably for high frequency observations without judicious
hyper-parameter tuning).

The PDRAs will work with faculty across the multi-university Hub, but
will be employed by and directly supervised by faculty within the
Mathematical Institute at the University of Oxford. Faculty within
the Mathematical Institute associated with the above work packages
include Profs. Cartis, Cohen, Hauser, Lambiotte, Reisinger, Sirignano,
and Tanner.

These are two-year, fixed-term position, funded by a research grant
from the EPSRC. The starting date of this position is flexible with an
earliest start date of 01 March 2025.

The successful candidates will be expected to conduct research which
falls within the remit of this large-scale project and will have the
opportunity to do so collaboratively with other members of the hub,
both at Oxford and/or with hub partners which include universities as
well as companies and governmental organisations.

They will contribute to the activities of the wider machine learning
and data science research group and write up the results of their
work, with co-authors, for publication in refereed journals and
proceedings. There will be opportunities to contribute a small amount
of teaching to the department, of at most three hours a week during
the academic terms.

You will have, or be close to completing, a PhD in mathematics or a
related discipline, and possess sufficient specialist knowledge in the
discipline to work within established research programmes. Excellent
communication skills are essential, including the ability to write for
publication, present research proposals and results, and represent the
research group at meetings.

We proudly hold a departmental Athena SWAN Silver Award and an
institutional Race Equality Charter Bronze Award, which guide our
progress towards advancing racial and gender equality. As part of our
strategic aim to improve staff equality and diversity, we would
particularly welcome applications from women and BME candidates, who
are currently under-represented in positions of this type within the
department.

Please direct informal enquiries to the Recruitment Coordinator
(email: recruitment@maths.ox.ac.uk), quoting vacancy reference 176180.

Applicants will be selected for interview purely based on their
ability to satisfy the selection criteria as outlined in full in the
job description. You will be required to upload a statement setting
out how you meet the selection criteria, a curriculum vitae including
full list of publications, a statement of research interests, and the
contact details of two referees as part of your online
application. (NOTE: Applicants are responsible for contacting their
referees and making sure that their letters are received by the
closing date).
