Research Seminar Series

We run a DIR Seminar Series where group members, visitors and guests present their work followed by lively discussions. The seminars are run every Friday at 10am in the Informatics Forum. The organiser of the series is Dr Rosa Filgueira Vicente.

We also list talks relevant to our work in the seminar series from the Centre for Intelligent Systems and their Applications (CISA), the Software Systems and Processes research group (SPP).

A New Probabilistic Plan Recognition Algorithm Based on String Rewriting

CISA Seminar Series
Speaker: 
Christopher Geib

This work formalizes and discusses the implementation of a new, more efficient probabilistic plan recognition algorithm called Yet Another Probabilistic Plan Recognizer (Yappr). Yappr is based on weighted model counting, building its models using string rewriting rather than tree adjunction or other tree building methods used in previous work. Since model construction is often the most computationally expensive part of such algorithms, this results in significant reductions in the algorithm’s runtime.

Active Database Integration in Grids

NeSC Research Seminar Series
Speaker: 
Alex Wöhrer

A focus of Grid computing are data intensive applications. Additionally, database management systems (DBMS) are gaining on importance in many scientific disciplines for publication of research results.The employment of Service-oriented-Architecture (SoA) raises the question of how DBMSs and their built-in technologies can be best utilized in such environments. A common way is to pull out all required data for a certain task from a source and process it service side far away from the original source.

Towards New Models and Languages for Data Mining and Integration

e-Science Institute Public Lecture
Speaker: 
Peter Brezany

Data mining refers to extracting or "mining" knowledge from large amount of data. It has enjoyed great popularity and success, especially in commercial applications, in recent years. Several models of data mining processes were first proposed by vendors of data mining tools, like SEMMA (Sample, Explore, Modify, Model, Asses) by SAS. Later there was a relevant effort aiming at the design of a standard model resulting into the specification of the CRISP-DM (CRoss-Industry Standard Process for Data Mining), which was published in 2000.

Ontology-Based Automatic Workflow Composition for Analysing Ecological Videos

SSP Seminar Series
Speaker: 
Gaya Nadarajan

We present a semantics-based workflow composition system to assist automatic video processing for underwater ecological videos of varying qualities. The system utilises planning and ontologies, and may be used in a distributed computing environment, such as the Grid. An example workflow composition for video classification, fish detection and counting is demonstrated, providing insight into challenges for the full implementation of a planning-enacted workflow engine. Further steps for improvement in the generation of more scalable plans is discussed.

Modelling How People Learn in Games

Computational Thinking Seminar
Speaker: 
Ed Hopkins

Computing Nash equilibria in games is complex. Yet, economists still hope that such equilibria can be used to predict human behaviour in a range of economic and social situations. One possible reason for the validity of this approach is that by following simple adaptive rules people can find their way to equilibrium. Recent advances in the theory of learning in games shows that this can be the case. The talk will be an introduction to the theory and some remaining unresolved issues.

Reconciling Agent Theories by the Portrayal of Agent Interactions

CISA Seminar Series
Speaker: 
Paul Martin

Knowledge dissemination is motivated by and in turn motivates interaction within theory-driven multi-agent systems. Agents interpret their environment, drawing upon accessible data sources which may be incomplete or themselves the product of interpretation. Their conclusions are often in conflict, but the sheer volume of information precludes resolving every inconsistency.

Peer Ranking in OpenKnowledge

SSP Seminar Series
Speaker: 
Dave Robertson

Versions of the Page Rank algorithm have been used with great success by systems that rank Web pages for Web browsers. I shall describe a Peer Rank algorithm similar to Page Rank but adapted to sharing of interacting protocols peer to peer (in the style deployed in the OpenKnowledge system - see www.openk.org). I shall then show results from simulated peer groups that show how we can get population level behaviours from Peer Rank analogous to the ones that have made Page Rank so successful.
