Subject: IR Tools, MATLAB package for Iterative Regularization

We are pleased to announce the release of IR Tools, a new MATLAB
software package of iterative regularization methods and test problems
for large-scale linear inverse problems.

This software can be obtained from: .
A report describing the main features of the software, as well as
examples of its usage, can be found at: .

This software package serves two related purposes: we provide
implementations of a range of iterative solvers, including several
recently proposed methods that are not available elsewhere, and we
provide a set of large-scale test problems in the form of
discretizations of 2D linear inverse problems.

All the iterative methods are implemented in a very flexible fashion
that allows the problem's coefficient matrix to be available as a
(sparse) matrix, a function handle, or an object.  The most basic call
to all of the various iterative methods requires only this matrix and
the right hand side vector; if the method uses any special stopping
criteria, regularization parameters, etc., then default values are set
automatically by the code.  Moreover, through the use of an optional
input structure, the user can also have full control of any of the
algorithm parameters.  The test problems represent realistic
large-scale problems found in image reconstruction and several other
applications. The size, and other parameters, of these problems can be
chosen by the user.

Monday 10th - Tuesday 11th December 2018
Double Tree by Hilton Hotel London - West End

Data-driven analysis is increasingly on the critical path for
performance advantage in many organisations, both public and
commercial.  This raises continuous challenges for rigorous analysis
to derive reliable insights from data at very large scale, often with
potential artefacts and sampling bias, adding to change
variation. This conference brings together researchers and
practitioners to signpost developments in the state-of-the-art and
find common ground where theory and practice meet to maximise impact
in the digital economy. It is a forum for networking and to showcase
the very latest research in a broad range of topics.  Each session
will feature an invited talk by an expert speaker.

Invited Speakers: Sofia Olhede, UCL; Coralia Cartis, Oxford
University; Christian Steinruecken, Cambridge University; Armando
Vieira, Direct Line; Noel-Ann Bradshaw and Serge Plata, Sainsbury's

Papers will be accepted for the conference based on a 300-500 word
abstract for oral or poster presentation. We welcome abstracts to be
submitted by Friday 28 September 2018 via
