Situational Awareness and Adversarial Machine LearningRoss Anderson
Professor of Security Engineering, Cambridge University, UK
Abstract: As the large complex systems used in applications from autonomous vehicles through network defence to factory automation acquire components that use machine-learning algorithms, situational awareness will become ever more important. Modern machine-learning systems are vulnerable to adversarial inputs, just as humans are vulnerable to deception. Humans, and animals too, manage such risks by being sensitive to the presence of adversaries and taking extra care when an attack is more likely. In recent research, we have been exploring how adversarial samples can be detected more easily than they can be blocked, allowing systems to fall back to more cautious modes of operation. The interaction between machine learning components and service-denial attacks is a fascinating subject that few have studied so far. In short, while classical system resilience may be seen in terms of layered defence and redundancy, that of machine-learning systems may be much more human. Combining the two intelligently could be a new frontier for research.
Bio: Ross Anderson is Professor of Security Engineering at Cambridge University. He was one of the founders of the discipline of security economics, and leads the Cambridge Cybercrime Centre, which collects and analyses data about online wickedness. He was also a pioneer of prepayment metering, powerline communications, peer-to-peer systems, hardware tamper-resistance and API security. He is a Fellow of the Royal Society and the Royal Academy of Engineering, as well as a winner of the Lovelace Medal – the UK's top award in computing. He is also the author of the standard textbook "Security Engineering – A Guide to Building Dependable Distributed Systems"
Computation as a dynamical systemSusan Stepney
Professor of Computer Science and Director of the York Cross-disciplinary Centre for Systems Analysis, University of York, UK
Abstract: Computation is often thought of as a branch of discrete mathematics, using the Turing model. That model works well for conventional applications such as word processing, database transactions, and other discrete data processing applications. But much of the world’s computer power resides in embedded devices, sensing and controlling complex physical processes in the real world. Other computational models and paradigms might be better suited to such tasks. I will discuss regarding computation as an open dynamical system, with a particular focus on reservoir computing in non-silicon devices, including our recent work on using magnetic materials as computational substrates. This approach can support smart processing „at the edge“, allow a close integration of sensing and computing in a single conceptual model and physical package, and provides a uniform approach to embodying computation in other dynamical systems.
