Using Deep Reinforcement Learning to Coordinate Multi-Modal Journey Planning with Limited Transportation Capacity
(2021)Multi-modal journey planning for large numbers of simultaneous travellers is a challenging prob- lem, particularly in the presence of limited transportation capacity. Fundamental trade-offs exist between balancing the ... -
Using Distributed Technology for Teaching Distributed Systems
(Trinity College Dublin. Department of Computer Science, 1999-09)Current developments in multimedia and Internet technologies are enabling their wide use as a means for delivering education and training. There is much diversity and no single architecture has yet emerged as the ... -
Using Distributed W-Learning for Multi-Policy Optimization in Decentralized Autonomic Systems
(ACM, 2009)Distributed W-Learning (DWL) is a reinforcement learning-based algorithm for multi-policy optimization in agent-based systems. In this poster we propose the use of DWL for decentralized multi-policy optimization in autonomic ... -
Using Diversity in Preparing Ensembles of Classifiers Based on Different Feature Subsets to Minimize Generalization Error
(Trinity College Dublin, Department of Computer Science, 2001-04)It is well known that ensembles of predictors produce better accuracy than a single predictor provided there is diversity in the ensemble. This diversity manifests itself as disagreement or ambiguity among the ... -
Using Dynamic Proxies to Support RMI in a Mobile Environment
(Trinity College Dublin. Department of Computer Science, 2001-09)The emergence of small, mobile computing devices such as personal digital assistants and cellular telephones has been driven by advances in computing and wireless communication technologies. The development of distributed ... -
Using Early Stopping to Reduce Overfitting in Wrapper-Based Feature Weighting
(Trinity College Dublin, Department of Computer Science, 2005-05-18)It is acknowledged that overfitting can occur in feature selection using the wrapper method when there is a limited amount of training data available. It has also been shown that the severity of overfitting is related to ... -
Using Early-Stopping to Avoid Overfitting in Wrapper-Based Feature Selection Employing Stochastic Search
(Trinity College Dublin, Department of Computer Science, 2005-05-11)It is acknowledged that overfitting can occur in feature selection using the wrapper method when there is a limited amount of training data available. It has also been shown that the severity of overfitting is related ... -
Using Events to Implement a Distributed Worm in a Mobile Environment
(Trinity College Dublin. Department of Computer Science, 1999-09)A distributed system comprises a number of independent computers linked together by a network, running a set of software components residing on numerous machines, all working towards a common goal. A worm is a paradigm ... -
Using Expert-Derived Aesthetic Attributes to Help Users in Browsing Image Databases
(2011)Image repositories often contain a large amount of metadata about their content. However many resources, such as photographs, have inherent aesthetic qualities that can be difficult to describe in a semantically consistent ... -
Using Feedback in Collaborative Reinforcement Learning to Adaptively Optimise MANET Routing
(2005)Designers face many system optimization problems when building distributed systems. Traditionally, designers have relied on optimization techniques that require either prior knowledge or centrally managed runtime knowledge ... -
Using Fluid Models for AQM Evaluation
(Trinity College Dublin. Department of Computer Science, 2005-09)In spite of the congestion management mechanisms included in the TCP/IP protocol, the Internet still suffers from a lack of optimization in the way network overload is managed. One of the reasons for this is that the ... -
Using Group Communication to Support Inter-Vehicle Co-ordination
(Trinity College Dublin. Department of Computer Science, 2002-09)Recent advancements in wireless communication technology and portable computing are opening up exciting possibilities for the future of mobile network applications. One obvious domain for such mobile network applications ... -
Using group communication to support mobile augmented reality applications
(IEEE, 2002)Augmented reality and group communication in wireless ad-hoc networks form relatively new fields of research. When using group communication ordering and timeliness requirements are important. Moreover, when using ... -
Using hyperbolic geometry for visualisation of concept spaces for adaptive e-learning
(2006)The Concept Space is an important part of an adaptive eLearning course. Understanding its structure from a traditional concept map is not, however, always straightforward. Hyperbolic trees are one alternative representation ... -
Using Multimedia to Reveal the Hidden Code of Everyday Behaviour to Children with Autistic Spectrum Disorders (ASDs)
(2011)This paper describes a framework which was developed for carers (teachers and parents) to help them create personalised social stories for children with autistic spectrum disorders (ASDs). It explores the social challenges ... -
Using NLP Techniques to Enhance Content Discoverability and Reusability for Adaptive Systems
(Trinity College Dublin. School of Computer Science & Statistics. Discipline of Computer Science, 2019)The volume of digital content resources written as text documents is growing every day, at an unprecedented rate. Because this content is generally not structured as easy-to-handle units, it can be very difficult for users ... -

Using Ontology Design Patterns to Define SHACL Shapes
(CEUR-WS, 2018)SHACL shapes used for validation are not related to the axioms used in ontologies used to define the instances. One of the issues with using such axioms is their dependence on concepts which may not be used within the ... -
Using Pseudo Feedback to Improve Cross-Lingual Ontology Mapping
(Springer, 2011)Translation techniques are often employed by cross-lingual ontology mapping (CLOM) approaches to turn a cross-lingual mapping problem into a monolingual mapping problem which can then be solved by state of the art monolingual ...
