PhD Scholarship for Causal Explanation with Bayesian Networks project

Faculty / Portfolio: Faculty of Information Technology

Location: Clayton campus

Scholarship: Pro-rata of $26,682 p.a. full-time for 3 years (plus $5,000 travel money per year) and tuition fees for 3 years for international student.

Please note, International students on a student visa must have health cover for the length of their visa while studying in Australia and this is not covered by the scholarship. For more information on health cover, please see http://www.monash.edu/fees/other-fees-charges/overseas-health-cover.

The Opportunity

Expressions of Interest are sought from outstanding candidates to undertake PhD studies in the Faculty of Information Technology at Monash University.

Supervisor: Associate Professor Kevin Korb

This scholarship is attached to Associate Professor Kevin Korb’s project. The scholarship will be void if the applicant changes supervisor and/or project.

The Project

How to generate explanations from Bayesian networks is a long-standing problem that has attracted many different answers, for example, using mutual information (Suermondt, 1992, Explanation in Bayesian Belief Networks, PhD Stanford). Since those early days in the causal interpretation of Bayesian networks, the theory has flourished, especially in interventionist accounts of causation, for example in the work of computer scientists Judea Pearl (Causality, Cambridge  Univ, 2009) and Joe Halpern, and also in the work of philosophers of science (James Woodward, Chris Hitchcock inter alia).

Within this tradition we have recently developed a causal information theory that can assist understanding and using causal Bayesian networks, combining mutual information with an interventionist theory of causality (e.g., Korb, Nyberg & Hope, 2011, "A New Causal Power Theory"). While causal information  theory is a very promising tool, the theory itself is not fully developed and its precise application in making sense of causal explanations is not clear. Example of the former: multiple causes often interact with one another in their joint effects, but thus far accounts of the types of interactions  and how to measure them are deficient. Example of the latter: causal explanation depends upon context (e.g., what conditions are assumed as a part of a causal query), but how to translate explanatory context into conditions or settings for a causal Bayesian network is not well understood. This project  will aim to answer these questions.

This PhD project is funded with a full, independent scholarship and travel money and is part of a larger, international project aiming at using Bayesian networks to assist with argument analysis. The student will need to work within a team setting. A strong interest in philosophy of science, causal  Bayesian networks and argument analysis is required. The student will need a good background in either artificial intelligence (Bayesian networks), philosophy of science or mathematics (Bayesian methods). Application is open-ended (not tied to the 31 October round), but we would like to start the project  early in 2017.
