Reading is a complex process that involves integrating sensory information extracted from text with stored memories about word meanings, syntactic structures and general knowledge. Most reading research has focused on the processing of isolated words, but normal reading requires integration processes that are not necessary to recognise single words. This research uses tasks requiring sentence comprehension and measures of eye movements during reading to investigate how readers retrieve and combine information while reading to comprehend text. It will contribute to developing more comprehensive theories of normal reading that can inform methods of teaching reading and contribute to refinement of text recognition systems.Read moreRead less

Natural Language Processing (NLP) has progressed rapidly using corpus-based machine learning techniques. However, corpus development costs cause a ?data bottleneck? which prevents systems from reaching human competence. This project overcomes the difficulties of creating huge corpora by employing the innate language ability of untrained contributors. We will show how to automatically select and present examples, containing informative linguistic structures, which are most beneficial for training NLP systems. These examples will be analysed by many contributors whose responses will be automatically collated into corpora. Huge corpora are vital to emerging language technologies for managing textual information in the global economy.

takes significant skills to configure systems properly such that they
are safe from malicious attacks.
The proposed project aims at designing automatic systems which are
able to adapt to an existing network configuration and which detect
novel and unusual events. For this purpose we will use modern machine
learning techniques, mainly based on kernels. In particular, recently
developed algorithms to estimate the support of a distribution and
detect rare events will be employed in this context.
The project is in cooperation with Dr. Ralf Herbrich (Microsoft
Research, Cambridge).

Computer Vision concerns itself with understanding the world through the analysis of images obtained by a video or still camera. An important application is tracking of people in video and modelling their movements. This has evident applications in security, sport and entertainment. By enabling the computer to capture the motion of a subject in a video, we may detect suspicious activity in security, analyze the motion (golf-swing, diving style) of a sports-person, or capture the motion of an actor for animation or game applications. Development of a reliable technology requires new optimization techniques, which will place Australia at the forefront of the application of such research, commercially and for the public benefit.Read moreRead less

Auditory spatial perception during head movements. Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This w ....Auditory spatial perception during head movements. Orienting to stimuli frequently involves eye and head movements. This improves localisation, yet brings attendant problems (eg, blurring). These problems are well understood in vision, but not in audition, despite evidence for common neural mechanisms. We will examine auditory (and visual) localisation during head movements, showing head movements produce auditory suppression and spatial distortions (analogous to visual saccadic effects). This will demonstrate the malleability of auditory spatial perception and the impoverished sensitivity of audition during head and self-motion. Knowledge of these distortions will inform applications such as cockpit design, where orienting to auditory signals is common, and other human/computer interfaces.
