<br>
Chris Oates, Newcastle University <br>
<br>
The scale and complexity of modern scientific computer codes
typically precludes a detailed analysis of how the code is
numerically implemented. For example, multi-scale and
multi-physics models of the human heart call on diverse numerical
sub-routines to integrate differential equations, perform
interpolation and optimise over some parameters of the model. As
such, the computer output is acknowledged to be inexact and some
alternative form of uncertainty quantification is needed for the
output to be properly interpreted. This talk will provide an
introduction to Bayesian probabilistic numerical methods, which
aim to provide probabilistic uncertainty quantification for
computer code output. These methods are composed of "modules" and
recent work on a novel module for the iterative solution of large
linear systems will be presented in detail.</span><br>
