Computational Fair Division: Towards a Fairer World
Fair Division is a rich field that has had contributions from various branches of the social sciences. Fairness is a central requirement when making collective decisions, allocating tasks, dividing resources, forming representative committees, or splitting costs. In computer science, as we endeavour to build new multi-agent systems, mechanisms, and protocols, fairness comes up as an important concern as well. In this talk, I will discuss the exciting interaction between computer science and fair division. In particular, I will talk about recent work on so called “cake cutting algorithms”.

Connecting through feedback
As a teacher of primarily first year students, the growing disconnect between the academic requirements of the discipline and the academic capital of many students has become more and more apparent to me. This disconnect has been particularly evident in a consistent decline in students’ performance in assessments which in many cases has led to subsequent attrition from the program.
The responsibility to find ways to address this disconnect therefore seemed (at least, in part) to lie with me. After receiving an end of semester Student Evaluation of Course (SEC) survey score of 3.6 out of 5 for Question 2: “The assessment was clear and fair” in Semester 1, 2010, for an introductory computer architecture course, it was clear to me that focusing on assessment and feedback was a good place to start. In particular, in order to understand the needs of the students and attempt to address the perceived deficits, much richer and more timely feedback than the formal end of semester course survey was required.
This presentation will discuss a number of innovative practices for connecting with students by eliciting feedback in a timely manner and closing the feedback loop. It will discuss a model for developing a local culture in which academics are invited to share information about their students’ course experiences. By “Connecting through Feedback” in this way, students become empowered to take control of their own learning, and staff are empowered to break down barriers to collegial engagement by cooperatively exploring common issues and shared solutions.
Dr Sven Venema is a senior lecturer in the School of Information and Communication Technology at Griffith University. Dr Venema transcends the decline in educational capital of commencing IT students by creating supportive learning environments through comprehensive, innovative approaches to assessment and feedback. His unique, student-centred teaching practices empower students to take control of their own learning, cater to a diverse range of student needs and increase student confidence and engagement. Dr Venema’s original teaching methods are informed by scholarly research and have been the subject of conference presentations and journal articles.

Fuzzy Transfer Learning for Prediction
This presentation highlights the value of fuzzy transfer learning methods and related algorithms for handling complex prediction problems in rapidly-changing data distribution and data-shortage situations. It provides a framework for utilising previously-acquired knowledge to predict new but similar problems quickly and effectively supported by fuzzy system techniques. It systematically presents the developments in fuzzy transfer learning methods, including fuzzy domain adaptation and fuzzy cross-domain adaptation, for classifications and regression

Geolocation Understanding in Social Media for Point-of-interest Recommendation
Location data has been playing an important role in many social media applications, particularly the location-based services. However, publicity-visible location annotations are remarkably sparse in social media data, such as online images. In this talk, we introduce novel methods to estimate missing locations for social images by effectively fusing multi-modalities of social media data. Interestingly, by integrating visual data and location data, such as geo-tagged images and check-ins, important location proximities can be better understood and discovered, which will further facilitate user behaviour analytics.
Dr Zi Huang received her BSc degree from Tsinghua University, China, in 2001, and her PhD in Computer Science from the University of Queensland, Australia, in 2007. She is currently an ARC Future Fellow with the School of Information Technology and Electrical Engineering, University of Queensland. Her research interests include multimedia indexing and search, social data analysis and knowledge discovery.

Security and Privacy in Passive RFID Systems
Radio Frequency Identification (RFID) enables the automatic identification of objects using radio waves without the need for physical contact with the objects. RFID has been widely used in various fields such as logistics, manufacturing, pharmaceutical, supply chain management, healthcare, defense, aerospace and many other areas, apart from touching our everyday lives through RFID enabled car keys, ePassports, clothing, electronic items and others. However, the wide adoptions of RFID technologies also introduce serious security and privacy risks as the information stored in RFID tags can easily be retrieved by any malicious party with a compatible reader. In this talk we will introduce some security and privicy challenges in passive RFID technologies, and based on our research, we will outline a number of schemes for authentication, ownership transfer, secure search and grouping proof in passive mobile RFID systems.

Understanding change in complex environments
When we monitor a complex system, often we are more interested in what has changed, rather than what remains the same. Unsupervised methods in machine learning and data mining have made great progress in building models to explain complex data sets. For example, clustering methods can provide insights into the inherent structure or distribution of data for diverse applications such as market research or bioinformatics. However, traditional unsupervised learning methods tend to focus on building models of static snapshots of a data set. They don’t explicitly learn models of the dynamics of the underlying system. In particular, for many applications it is important to learn what has changed between successive snapshots of a system, such as how a customer behaviour has changed as a result of a marketing campaign, or how network traffic has changed as a result of a cyber attack. This presentation will give an overview of our contributions to the challenge of understanding change in data mining.
Chris Leckie is a Professor with the Department of Computing and Information Systems at the University of Melbourne.
