Subject: 8th IMA Conference on Mathematics in Defence and Security Mathematics for Decision Support
15 October 2025
The Catalyst, Newcastle upon Tyne, NE4 5TG
https://ima.org.uk/26135/8th-ima-conference-on-mathematics-in-defence-and-security-mathematics-for-decision-support/
Mathematics is at the heart of evidence-based decision support;
however, any decision requires data collection, data and signal
processing, communications and communication systems to reduce
cognitive burden for the decision maker and improve decision
making. It is also increasingly common for AI to play a role in
summation and processing, meaning that evidence is even more varied in
its utility and applicability. This conference will explore both the
state of the art in terms of data curation, signal processing,
communication and AI to support decision making as well as looking at
the impact of these systems on cognitive load. Importantly this
conference will focus on research that can start to explore the
confluence of these areas in order to underpin decision making in a
rigorous and integrated system. As mathematics begins to underpin more
of the decision-making process, so it becomes more important that that
mathematics is integrated and focussed on providing understandable
evidence to the decision maker. Therefore, how the mathematical
evidence is then communicated becomes as important as how the
mathematics is undertaken. The conference will aim to bring together
a wide variety of participants applying a variety of mathematical
methods with defence and security applications. The programme will
include invited speakers, presentations and poster sessions, as well
as refreshment breaks for informal discussions. It is aimed towards a
cross-discipline audience of mathematicians, scientists, engineers and
communicators from both industry and academia, in addition to
government and military personnel who have an interest in how
mathematics can be applied to defence and security problems. The scope
of the conference includes but is not limited to the following topics:
1. Mathematics for Decision Support
• Decision Support Systems for Defence
• Data mining and Statistical Learning
• Multi-objective and Multi-criteria Optimization
• Data Fusion Systems in Defence Applications
2. Signal Processing and Communications
• Multimodal Signal Processing
• Distributed Signal Processing
• Integrated Communications and Sensing Systems
• Sensor Management for Defence Applications
3. Artificial Intelligence and Machine Learning
• Machine Learning for Defence Applications
• Cognitive Systems to support Decision Making
• Data Collection and Curation for Defence
