A Case-Based Technique For Tracking Concept Drift In Spam Filtering, Sarah Jane Delany, Padraig Cunningham, Alexey Tsymbal, Lorcan Coyle

Spam filtering is a particularly challenging machine learning task as the data distribution and concept being learned changes over time. It exhibits a particularly awkward form of concept drift as the change is driven by spammers wishing to circumvent spam filters. In this paper we show that lazy learning techniques are appropriate for such dynamically changing contexts. We present a case-based system for spam filtering that can learn dynamically. We evaluate its performance as the case-base is updated with new cases. We also explore the benefit of periodically redoing the feature selection process to bring new features into play. Our …

Electromagnetic Measurement Of Spinal Curvature, Ronan Fitzmaurice, Ted Burke, Annraoi De Paor
Conference Papers
In this paper, we describe an original mathematical technique for calculating the position and orientation of an electromagnetic coil from a minimum of four collinear magnetic field measurements. This problem arose in the development of a system for evaluating the efficacy of inflatable back rafts designed to mitigate complications that arise from the immobilisation of patients with suspected spinal injuries on spinal boards during transport to hospital. Electromagnetic markers are attached to points of interest on the back of an immobilised test subject. Spinal curvature is then measured by passing a magnetometer underneath the board.
An Electro-Oculogram Based System For Communication And Control Using Target Position Variation, Ronan Fitzmaurice, Ted Burke, Annraoi De Paor
An Electro-Oculogram Based System For Communication And Control Using Target Position Variation, Ronan Fitzmaurice, Ted Burke, Annraoi De Paor
Conference Papers
In this paper we describe a novel mode of human computer interaction based on gaze tracking using the electro-oculogram (EOG). Despite the relative simplicity of recording this signal, it is often discounted as a reliable method of gaze tracking because of problems arising from changing sensitivity and DC drift. We describe an original technique, Target Position Variation (TPV), which addresses this issue by presenting moving icons which, when followed with the eye, create a corresponding pattern in the EOG signal which can be used to infer the correct gaze position and to compensate for variations in sensitivity.

Design Of Mobile Phone Applications For Point-Of-Care Test Result Validation., John Mcgrory, Owen Lynch, Eugene Coyle
Conference Papers
Patients with many different conditions are required to take the management of their condition into their own hands and perform Point of Care Testing (POCT) at home. However, this raises quality control issues that would not arise in a clinical setting, since the sample acquisition and testing procedures are not overseen by professional hospital staff. Another major issue, the main focus of this research, is that results from such tests are not clinically validated to ensure that they are plausible for that patient at the time of testing. In hospital, tests taken by clinicians are validated by hi-tech computerised validation …
Design Of A Wireless System For Patient-Hospital Communication And Result Validation In Point Of Care Testing, John Mcgrory, Owen Lynch, Eugene Coyle
Design Of A Wireless System For Patient-Hospital Communication And Result Validation In Point Of Care Testing, John Mcgrory, Owen Lynch, Eugene Coyle
Conference Papers
This paper discuses mobile phone (cell phone) and wireless applications for linking patients who manage their healthcare outside the hospital using Point of Care Testing (POCT) to hospital information systems (HIS). Certain medical conditions require patients to manage their healthcare by performing on themselves POC testing and act faithfully on the result. This raises quality control issue, as these POC samples and testing procedures are not independently overseen by professional hospital staff. In hospitals, samples taken by clinicians are validated by hi-tech computerised validation systems to ensure plausibility, before physicians rely on them. Patients in the home must often use …
Information Delivery On Mobile Devices Using Contour Icon Sonification, Charlie Cullen, Eugene Coyle
Information Delivery On Mobile Devices Using Contour Icon Sonification, Charlie Cullen, Eugene Coyle
Conference papers
This paper examines the use of musical patterns to convey information, specifically in the context of mobile devices. Existing mechanisms (such as the popularity of the Morse code SMS alert) suggest that the use of musical patterns on mobile devices can be a very efficient and powerful method of data delivery. Unique musical patterns based on templates known as Contour Icons are used to represent specific data variables, with the output rendering of these patterns being referred to as a Sonification of that data. Contour Icon patterns mimic basic shapes and structures, thus providing listeners with a means of categorising …
Trioson: A Graphical User Interface For Pattern Sonification, Charlie Cullen, Eugene Coyle
Trioson: A Graphical User Interface For Pattern Sonification, Charlie Cullen, Eugene Coyle
Conference papers
The TrioSon software allows users to map musical patterns to input data variables via a graphical user interface (GUI). The application is a Java routine designed to take input files of standard Comma Separated Values (CSV) format and output Standard Midi Files (SMF) using the internal Java Sound API. TrioSon renders output Sonifications from input data files for up to 3 user-defined parameters, allocated as bass, chord and melody instruments for the purposes of arrangement. In this manner each parameter concerned is distinguished by its individual instrumental timbre, with the option of rendering any combination of 1 to 3 parameters …

Information Delivery On Mobile Devices Using Boolean Sonification Patterns, Charlie Cullen, Eugene Coyle
Conference papers
Sonification is the means by which non-speech audio can be used to convey information. Existing work has produced methods for delivering information in a wide range of fields, and recent work has considered the huge potential of mobile devices for Sonification. Boolean Sonification is a method of defining two related musical patterns as boolean conditions (true/false, yes/no etc.), such that one is considered contrary to the other by the listener. The final pattern set ideally comprises of two musical events that are closely enough related as to be considered a group, yet distinct enough to be perceived as separate entities. …

Experiences Teaching Website Engagibility To Computer Science Students., Pan Liqiang, Bryan Duggan, Ronan Fitzpatrick
Conference papers
In the second year of our degree program, DT228 students study a subject called Web Development. In this paper we describe our studio classroom based teaching approach to this subject and explain how using this approach has enabled us to expand the scope of the course to include the important concept of website engagibility. We present a summary of current theories on website engagibility and explain how we incorporated these theories into the course. We further describe an experiment which we carried out in order to encourage students to reflect on website engagibility and incorporate it into their continuous assessments.

There is a continuing need for quality eCommerce websites which satisfy their owner’s perspective of quality of design and visitor’s perspective of quality of use. More particularly there is a need for website owners to be able to specify what constitutes a website that will fully engage site visitors and consequently what needs to be designed into the website in order to insure return on investment. This paper argues that the term usability is inappropriate to quality websites and that website engagibility is a step beyond usability. The paper reports continuing research which seeks to identify the requirements of website …
