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 Call for Abstracts Abstracts will be considered for the conference based on a 300 word abstract for oral presentation. Abstracts should be submitted by 23rd May 2025 via https://my.ima.org.uk/
