Online Event: IMA Early Career Mathematicians’ Spring Conference 2021


What is the conference about?

The conference will interest mathematicians early in their career, in academia and industry, students of mathematical sciences, as well as those with an interest in the subject. It will feature plenary talks from distinguished speakers covering a wide range of subjects, as well as a networking activities.

This is a perfect opportunity to learn about fascinating areas of mathematics and its applications from people that work on them, whilst also providing you the chance to become more involved with a professional body of mathematics. The networking event will allow you the opportunity to meet people with similar interests and find out more about the wide range of careers that are available.

Abstracts

Mihaela Rosca  – “Generative modelling using deep learning methods”

Recent years have seen great progress in the ability to learn and model probability distributions using deep learning methods. We will take a journey into the objectives used to train these models, from maximum likelihood to GAN training, and discover the challenges and benefits of modelling probability distributions using neural networks. We will end with a showcase of a few impressive results obtained using the described approaches.

Dr Matthew Durey (MIT) – “Pilot-wave hydrodynamics”

A millimetric droplet of silicone oil may bounce and self-propel on the free surface of a vertically vibrating fluid bath. The droplet possesses a ‘path memory’ of its prior trajectory, encoded within its accompanying guiding, or ‘pilot’, wave field. We here explore connections between the dynamics of this hydrodynamic pilot-wave system and phenomena previously thought to be exclusive to the quantum realm. We also discuss this hydrodynamic pilot-wave system in the context of a broader class of problems arising in fluid mechanics and applied dynamical systems.

Prof Nick Higham – “Completing, Thresholding, and Factorizing Symmetric Positive Definite Matrices”

Symmetric positive definite matrices are ubiquitous, often appearing in the form of covariance matrices or correlation matrices. In some situations not all the elements are known and it desired to fill in the missing ones in order to achieve a positive definite matrix; this is the completion problem. A kind of converse arises when smaller elements, known only to low confidence, are replaced by zeros and we want to know whether this so-called thresholding preserve definiteness. Having finally obtained a positive definite matrix A we are likely to want to solve a linear system Ax = b. What is the most efficient way to do so on modern computers? We briefly address all these questions and explain how they arise in practical applications.

The ECM Branch

The Early Career Mathematicians’ (ECM) Branch is designed for those with a maths degree who are within the first 15 years of graduating, or, those without a degree who are within the first 15 years of membership. The ECM group has been set up to engage and empower ECM, and students of mathematics at university, to provide them with support and an opportunity to network.
