Abstract:

There has been a dramatic growth in the number and range of Internet of Things (IoT) sensors that generate healthcare data. These sensors stream high-dimensional time series data that must be analysed in order to provide the insights into medical conditions that can improve patient healthcare. This raises both statistical and computational challenges, including where to deploy the streaming data analytics, given that a typical healthcare IoT system will combine a highly diverse set of components with very varied computational characteristics, e.g. sensors, mobile phones and clouds. Different partitionings of the analytics across these components can dramatically affect key factors such as the battery life of the sensors, and the overall performance. In this work we describe a method for automatically partitioning stream processing across a set of components in order to optimise for a range of factors including sensor battery life and communications bandwidth. We illustrate this using our implementation of a statistical model predicting the glucose levels of type II diabetes patients in order to reduce the risk of hyperglycaemia.

Abstract:

Apprenticeship degrees have sprung up so fast that there has been little time for us all to reflect on how this apparently new form of education, to universities at least, could significantly affect our educational offerings. The University of Glasgow has been undertaking some preparatory work for Skills Development Scotland prior to running its apprenticeship degree in software engineering, and this has afforded us some time to see what others nationally and internationally have been doing, and to consider relevant aspects of the literature, as well as consult with industry. One view that we are developing of these degrees is as a true evolution of typical, largely campus-based, software engineering degrees, towards a full-blown professional degree such as in medicine, where university and hospitals are in real partnership over the training of doctors. In this talk, I will outline our thinking and raise a number of issues for discussion. In suggesting a closer relationship with industry in a talk in St Andrews, I do not of course miss the irony that industry accreditation was never (I believe) something that St Andrews was particularly bothered about – thinking that my BSc (Hons) 1988 is not accredited!

Abstract:

Tissue ablation is a widely used treatment in both the cosmetic and medical sectors, for treating various diseases or to improve cosmetic outlooks. We present our tissue ablation model which can predict the depth of ablation, and the surrounding thermal damage caused by the laser during ablation.

“Non-diffracting” beams have a multitude of uses in physics, from optical manipulation to improved microscopy light sources. For the first time we show that these beams can be modelled using Monte Carlo radiation transport method. Allowing better insight into how these beams propagate in a turbid medium.

Both of these projects use the Monte Carlo radiation transport method (MCRT) to simulate light transport. The MCRT method is a powerful numerical method that can solve light transport though heavily scattering and absorbing mediums, such as biological tissues. The method is extremely flexible and can model arbitrary geometries and light sources. MCRT can also model the various micro-physics of the simulated medium, such as polarisation, fluorescence, and Raman scattering. This talk will give an overview of our group’s work, with particular focus on simulating tissue ablation, and modelling “non-diffracting” beams.

Abstract:

The most famous single-player card game is ‘Klondike’, but our ignorance of its winnability percentage has been called “one of the embarrassments of applied mathematics”. Klondike is just one of many single-player card games, generically called ‘solitaire’ or ‘patience’ games, for which players have long wanted to know how likely a particular game is to be winnable for a random deal. A number of different games have been studied empirically in the academic literature and by non-academic enthusiasts.

Here we show that a single general purpose Artificial Intelligence program, called “Solvitaire”, can be used to determine the winnability percentage of approximately 30 different single-player card games with a 95% confidence interval of ± 0.1% or better. For example, we report the winnability of Klondike to within 0.10% (in the ‘thoughtful’ variant where the player knows the location of all cards). This is a 30-fold reduction in confidence interval, and almost all our results are either entirely new or represent significant improvements on previous knowledge.

Ian Gent is professor of Computer Science at the University of St Andrews. His mother taught him to play patience and herself showed endless patience when he “helped” her by taking complete control of the game. A program to play a patience game was one of the programs he wrote on his 1982 Sinclair Spectrum now on the wall outside his office.

Abstract:

This talk is an overview of the VAMPIRE (Vessel Assessment and Measurement Platform for Images of the REtina) project, an international and interdisciplinary research initiative created and led by the Universities of Dundee and Edinburgh in Scotland, UK, since the early 2000s. VAMPIRE research focuses on the eye as a source of biomarkers for systemic diseases (e.g. cardiovascular, diabetes, dementia) and cognitive decline, as well as on eye-specific diseases. VAMPIRE is highly interdisciplinary, bringing together medical image analysis, machine learning and data analysis, medical research, and data governance and management at scale. The talk introduces concisely the aims, structure and current results of VAMPIRE, the current vision for effective translation to society, and the several non-technical factors complementing technical research needed to achieve effective translation.
