Vortrag von Dr. Peter Lewis am 6. November: "Engineering Self-aware Computing Systems"

Am 6. November 2012 hält Dr. Peter Lewis (CERCIA, University of Birmingham) einen Vortrag zum Thema "Engineering Self-aware Computing Systems". Der Vortag gehört zum aktuell laufenden Informatikkolloquium in diesem Semester.


Novel computing systems are increasingly being composed of large numbers of heterogeneous components, each with potentially different goals or local perspectives, and connected in networks which change over time. Management of such systems quickly becomes infeasible for humans. As such, future computing systems should be able to achieve advanced levels of autonomous adaptive behaviour. In order for a system to effectively adapt itself in such a context, its ability to be self-aware becomes important.

There are several clusters of research in computer science and engineering which have used the term self-awareness explicitly. However, there is no general methodology or common framework for describing or benchmarking the self-awareness capabilities of these systems, or the benefits that self-awareness might bring. In this talk, I shall begin by surveying definitions and current understanding of self-awareness in psychology. I will then attempt to translate these concepts from psychology to the computing domain, and show how their explicit consideration may be beneficial in the engineering of adaptive computing systems. I will discuss how computational self-awareness may include knowledge of internal state, history, social or physical environment, goals, and perhaps even a system's own way of representing or reasoning about these things.

Finally, I will describe our work in an example application domain, distributed smart-camera networks, where decentralised self-awareness can increase runtime adaptivity and robustness, and avoid the need for a priori information at design-time.

Das Kolloquium findet um 18 Uhr im Hörsaal O2 statt. Bei Rückfragen wenden Sie sich bitte an Frau Bewermeyer, Institut für Informatik, Telefon: 05251/60-6695, E-Mail

Alle Interessierten sind herzlich willkommen!


Peter Lewis is a post-doctoral research fellow at the Centre of Excellence for Research in Computational Intelligence and Applications (CERCIA) in the School of Computer Science at the University of Birmingham, UK. His current research is concerned with investigating algorithms and techniques for achieving self-awareness and self-expression in decentralized computational systems. Particular focuses include economics-inspired computational techniques and online learning algorithms, such as those using evolutionary computation and other nature-inspired techniques.
