Autopilot: Simulating Changing Concepts In Real Data, Patrick Lindstrom, Sarah Jane Delany, Brian Mac Namee
Conference papers
An increasingly important area in supervised incremental learning is learning in the presence of changing concepts. Research into concept drift is hampered by the lack of availability of controllable `real life' datasets. In this paper we propose an approach for generating real life data over which we have control of the concept and can generate data exhibiting different types of concept drift. The approach uses a 3-D driving game to produce a data stream of instances describing how to drive around a track. The classification problem is learning the driving technique of the driver, which can be affected by changes …

Referring Expression Generation Challenge 2008 Dit System Description, John D. Kelleher, Brian Mac Namee
Conference papers
This section describes the two systems developed at DIT for the attribute selection track of the REG 2008 challenge. Both of theses systems use an incremental greedy search to generate descriptions, similar to the incremental algorithm described in (Dale and Reiter, 1995). The output of these incremental algorithms are, to a large extent, determined by the order in which the algorithm tests the target object’s attributes for inclusion in the description. Indeed, the major difference between the two systems described in this section is the mechanism used to order the attributes for inclusion.

Physics-Based Table-Top Mixed Reality Games, Qingqing Dong, Zhongyi Sun, Brian Mac Namee
Conference papers
Mixed reality applications use techniques from computer vision, augmented reality and virtual reality to allow real and virtual objects interact physically together on a user’s computer screen. This paper will describe two mixed reality applications which allow the user to play games that appear to take place on top of their physical desk. The games described are a desktop racing game and a desktop based game of ten pin bowling. In the desktop racing game virtual cars, controlled by the user, interact with both virtual objects (such as trees, walls and lampposts) and real ones (such as ramps and blocks). …
