Optimal route planning for hitchhiking
In this thesis, we considered a problem of optimal route planning for hitchhikers. We formalized the hitchhiker's problem and proposed a graph-based model to represent the set of all possible travel options for a hitchhiker. ...
Validating context-driven features of mobile applications using laboratory testing
Mobile devices such as smartphones and tablets now embed a variety of sensors that can provide context-driven services to increasingly large user bases. Driven by the richness of heterogeneous data and machine learning ...
Change Point Detection in High-Dimensional Streaming Time Series Data
In the Internet of Things (IoT), data is continuously recorded from different data sources, such as sensors for monitoring purposes. Some examples of these IoT based sensing platforms are loop detector sensors employed in ...
Exploring knowledge leakage risk in knowledge-intensive organisations: behavioural aspects and key controls
Knowledge leakage poses a critical risk to the competitiveness advantages of knowledge-intensive organisations. Although knowledge leakage is a human-centric security issue, little is known in relation to the key factors ...
Understanding information security strategy in organisations
The research topic under investigation in this thesis is information security strategy in organisations and I propose a substantive theory for understanding this phenomenon under varying environmental and internal conditions. ...
Probabilistic models for aggregating crowdsourced annotations
This thesis explores aggregation methods for crowdsourced annotations. Crowdsourcing is a popular means of creating training and evaluation datasets for machine learning, e.g. used for computer vision, natural language ...
The use of clinical decision support systems for the development of medical students’ diagnostic reasoning skills
Computer-aided learning systems (e-learning systems) can help medical students gain more experience with diagnostic reasoning and decision-making. Within this context, providing feedback that matches student needs (i.e. ...
Performances and publics while watching and live-streaming video games on Twitch.tv
Twitch.tv is a video live-streaming website that launched in 2011 with content centred mostly, but not exclusively, on the playing of video games. Streamers or broadcasters play games in real-time often accompanied by a ...
Effective, efficient and private similarity search in spatiotemporal trajectory datasets
Location-aware devices have become an integral part of our daily lives. With their widespread use, a tremendous amount of data in the form of spatiotemporal trajectory datasets have become available. The analysis of ...
On the use of prior and external knowledge in neural sequence models
Neural sequence models have recently achieved great success across various natural language processing tasks. In practice, neural sequence models require massive amount of annotated training data to reach their desirable ...
