Is It Worth It? Budget-Related Evaluation Metrics For Model Selection, Filip Klubicka, Giancarlo Salton, John D. Kelleher Jan 2018

Is It Worth It? Budget-Related Evaluation Metrics For Model Selection, Filip Klubicka, Giancarlo Salton, John D. Kelleher

Conference papers

Projects that set out to create a linguistic resource often do so by using a machine learning model that pre-annotates or filters the content that goes through to a human annotator, before going into the final version of the resource. However, available budgets are often limited, and the amount of data that is available exceeds the amount of annotation that can be done. Thus, in order to optimize the benefit from the invested human work, we argue that the decision on which predictive model one should employ depends not only on generalized evaluation metrics, such as accuracy and F-score, but …

Adaptive Environments For Enabling Senior Citizens: An Holistic Assessment Tool For Housing Design And Iot-Based Technologies, Matteo Zallio, Damon Berry, Niccolò Casiddu

Conference papers

The population of older adults will continuously increase over the coming decades. As they get older, people will require assistance and regular monitoring, with higher costs for welfare system and families. Two vital aspects of a healthy lifestyle, are domestic autonomy and maintenance of relationships within the neighborhood. This leads to an interesting research issue: “Could houses and appliances have the potential to improve autonomy and quality of life of citizens? Which methods and tools could enhance wellbeing and healthy conditions? The house has the potential to be a safe, adaptive environment, integrated with technologies for life support. This work …


Judging Emotion From Low-Pass Filtered Naturalistic Emotional Speech, John Snel, Charlie Cullen Sep 2013

Judging Emotion From Low-Pass Filtered Naturalistic Emotional Speech, John Snel, Charlie Cullen

Conference papers

In speech, low frequency regions play a significant role in paralinguistic communication such as the conveyance of emotion or mood. The extent to which lower frequencies signify or contribute to affective speech is still an area for investigation. To investigate paralinguistic cues, and remove interference from linguistic cues, researchers can low-pass filter the speech signal on the assumption that certain acoustic cues characterizing affect are still discernible. Low-pass filtering is a practical technique to investigate paralinguistic phenomena, and is used here to investigate the inference of naturalistic emotional speech. This paper investigates how listeners perceive the level of Activation, and …


Obtaining Speech Assets For Judgement Analysis On Low-Pass Filtered Emotional Speech, John Snel, Charlie Cullen Jan 2011

Obtaining Speech Assets For Judgement Analysis On Low-Pass Filtered Emotional Speech, John Snel, Charlie Cullen

Conference papers

Investigating the emotional content in speech from acoustic characteristics requires separating the semantic con- tent from the acoustic channel. For natural emotional speech, a widely used method to separate the two channels is the use of cue masking. Our objective is to investigate the use of cue masking in non-acted emotional speech by analyzing the extent to which filtering impacts the perception of emotional content of the modified speech material. However, obtaining a corpus of emotional speech can be quite difficult whereby verifying the emotional content is an issue thoroughly discussed. Currently, speech research is showing a tendency toward constructing …


Harmonically Combined Contour Icons For Concurrent Auditory Display, Charlie Cullen, Eugene Coyle Jan 2006

Harmonically Combined Contour Icons For Concurrent Auditory Display, Charlie Cullen, Eugene Coyle

Conference papers

This paper considers the harmonic combination of basic melodic shapes known as contour icons in concurrent auditory displays. Existing work in the field (such as that concerning earcons) has considered the combination of patterns designed using low level cognitive features, and so effective streaming is difficult. This work investigates means by which musical patterns with high level cognitive features (such as contour) representing data values can be rendered concurrently, so that multiple data sets can be effectively conveyed using an auditory display. The detection and comprehension of harmonically combined contour icons was tested in comparison to those combined uniquely (non …


Musical Pattern Design Using Contour Icons, Charlie Cullen, Eugene Coyle Jan 2006

Musical Pattern Design Using Contour Icons, Charlie Cullen, Eugene Coyle

Conference papers

This paper considers the use of Contour Icons in the design and implementation of musical patterns, for the purposes of detection and recognition. Research work had endeavoured to deliver musical patterns that were both distinct and memorable, and to this end a set of basic melodic shapes were introduced using a Sonification application called TrioSon that had been designed for the purpose. Existing work in the field (such as that concerning Earcon design) has considered the mechanisms by which patterns may be made distinctive, but it is argued that separate consideration must be given to the method of making such …


Information Delivery On Mobile Devices Using Contour Icon Sonification, Charlie Cullen, Eugene Coyle Jan 2005

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 Jan 2005

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 Jan 2005

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. …


Analysis Of Data Sets Using Trio Sonification, Charlie Cullen, Eugene Coyle Jan 2004

Analysis Of Data Sets Using Trio Sonification, Charlie Cullen, Eugene Coyle

Conference papers

Recent advances in technology have suggested that sound and audio play a far greater part in our daily working lives than ever before. Mobile phone ring tones are now based upon polyphonic music sequences that allow relatively complex audio to be generated from a handset by way of conveying information (i.e. a call or message is incoming). This real world example of sonification suggests that far more could be made of sonification techniques for analysis- particularly in the business environment. One advantage of sonification is its relatively hands free nature in that once a sequence is being played it does …


Orchestration Within The Sonification Of Basic Data Sets, Charlie Cullen, Eugene Coyle Jan 2004

Orchestration Within The Sonification Of Basic Data Sets, Charlie Cullen, Eugene Coyle

Conference papers

The use of sonification as a means of representing and analysing data has become a growing field of research in recent years and as such has become a far more accepted means of working with data. Existing work carried out as part of this research has focused primarily on the sonification of DNA/RNA sequences and their subsequent protein structures for the purposes of analysis. This sonification work raised many questions as regards the need for sequences to be set to music in a standard manner so that different strands could be analysed by comparison, and hence the orchestration and instrumentation …


Rhythmic Parsing Of Sonified Dna And Rna Sequences, Charlie Cullen, Eugene Coyle Jan 2003

Rhythmic Parsing Of Sonified Dna And Rna Sequences, Charlie Cullen, Eugene Coyle

Conference papers

Sonification allows existing mathematical data to be used as the model for audio output, notably that the audio produced is related to or representative of that data in some way. Existing work in the field has been largely focused on the aesthetic tailoring of the output audio for compositional benefit rather than as a framework for audio representation and analysis. It is the goal of this research to apply existing techniques for pitch substitution to an analytical method that seeks to define and represent patterns within existing data sets (primarily DNA and RNA sequences). It is often the case that …
