Learning Hierarchical Sparse Filters for Feature Matching
A common problem in computer vision is to match corresponding points between images. The success of computer vision has usually relied on having good feature representations, which are usually hand-crafted and thus require ... -
Modelling and Simulation of GeneRegulatory Networks: Segmentation genes of Honeybee (Apis mellifera) embryos
The developmental process involves interactions between thousands and thousands genes. The reasons why, where, and when the genes are expressed can be revealed in the topology of a Gene Regulatory Network (GRN). In this ... -
Modelling type-denoting concepts and words in a simulation of vocabulary development.
Luc Steels proposes a mechanism by which a community of agents is able to negotiate a common vocabulary for referring to objects in their environment, using two simple games. In a ‘discrimination game’, an agent equipped ... -
Neural network models for learning representations of 3D objects via tactile exploration
How does the brain learn the geometry of 3D objects? While the question has been explored for decades, it remains poorly understood. Most researchers considering this question focus on vision. However, infants first learn ... -
A Perceptual Basis for Noun Phrase Syntax
Human language is the result of both biological and cultural evolution. To have the best chance of understanding language we must seek all the constraints of that evolution. In the first part of my thesis I propose the ... -
Perspectives on belief and change
This thesis is about logical models of belief (and knowledge) representation and belief change. This means that we propose logical systems which are intended to represent how agents perceive a situation and reason about ... -
Physically exploring volume data using hand-held mobile hardware
Volume data is widely used in many different domains including medical imaging. The primary platform to visualize volume data is usually desktop hardware, while the use of hand-held mobile devices to browse volume data is ... -
Physics-Based Simulation of Canine Gait
For most animals, locomotion is essential for survival, and it is advantageous to do this efficiently and with minimal neural control. Research has shown that efficient walking is possible without control, resulting purely ... -
Power Adaptive Communication for Wireless Body Area Networks
Fast advancement in physiological sensors, low-power circuits, and short-range wireless communications has enabled the development and deployment of ubiquitous wearable networks called Wireless Body Area Networks (WBANs) ... -
Power Line Detection from Mobile Devices
Overhead power lines are a common structure used to transmit and deliver electricity to consumers. The structures, comprised primarily of power poles and power lines, are frequently upgraded, repaired, and maintained by ... -
Power Modelling in Multicore Computing
Power consumption has long been a concern for portable consumer electronics, but has recently become an increasing concern for larger, power-hungry systems such as servers and clusters. This concern has arisen from the ... -
Protocol Support for Adaptive Streaming Media
The Internet has already become a platform for multimedia rich communication, collaboration and entertaining applications. A majority of these applications are based on a technology known as audio-video streaming. Streaming ... -
QoS-based Handover for Next Generation Wireless Networks
The deployment of the Next Generation Wireless Network (NGWN) involves different service providers, different radio access technologies and multi-mode mobile terminals that have to be compatible with existing services and ... -
Reading the brain’s personality: using machine learning to investigate the relationships between EEG and depressivity
Electroencephalography (EEG) measures electrical signals on the scalp and can give information about processes near the surface of the brain (cortex). The goal of our research was to create models that predict depressivity ... -
Receiver Driven Email Delivery
Spam has become a serious problem to email users all over the world. Most of the daily email messages we are receiving consists of unwanted spam messages. Although there are various methods to reduce the quantity of spam ... -
Red blood cell segmentation using guided contour tracing
We present a model-based contour tracing approach to the problem of automatically segmenting a Scanning Electron Microscope image of red blood cells. These images characteristically have high numbers of overlapping cells ... -
Routing and Wavelength Assignment for Multicast Communication in Optical Network-on-Chip
An Optical Network-on-Chip (ONoC) is an emerging chip-level optical interconnection technology to realise high-performance and power-efficient inter-core communication for many-core processors. Within the field, multicast ... -
Self localisation in indoor environments using machine vision
The performance of outdoor positioning has become excellent with the emergence of Global Positioning System (GPS), but GPS is not reliable indoors. The ability of a system to perform indoor positioning without GPS is still ... -
Semi-automated assessment of SQL schemas via database unit testing
A key skill for students learning relational database concepts is how to design and implement a database schema in SQL. This skill is often tested in an assignment where students derive a schema from a natural language ... -
Some neuro-computational investigations into the reviewing of object-files
When a person attends to an object, a temporary working memory representation is created for it, specific to that individual “token” object. This differs from more general accumulated memories for “types” of objects. Kahneman, ...
