(1996)This paper describes an algorithm that infers a hierarchical structure from a sequence of discrete symbols by replacing phrases which appear more than once by a grammatical rule that generates the phrase, and continuing ... -
(Springer Berlin Heidelberg, 2013)Evolutionary data mining is used in this paper to investigate the concept of support and resistance levels in financial markets. Specifically, Differential Evolution is used to learn support/resistance levels from price ...

(2006)Digital libraries and search engines are now well-equipped to find images of documents based on queries. Many images of music scores are now available, often mixed up with textual documents and images. For example, using ... -
(World Scientific Publishing, 2006)We consider the identities of a variety of semigroup-related algebras modelling the algebra of partial maps. We show that the identities are intimately related to a weak semigroup deductive system and we show that the ... -
(2001)This paper presents an idiomatic construct for µ-charts which reflects the high-level specification construct of synchronization between activities. This, amongst others, has emerged as a common and useful idea during our ... -
(2009)The physical environment of a classroom—how space is organized and controlled—impacts the use of technology within that setting. This paper presents the initial rationale for choosing an interactive whiteboard (IWB) as the ... -
(2003)We examine numerically the influence of Hall effect corrections to Ohm's law upon the decay of homogeneous compressible magnetohydrodynamic turbulence and conclude that there are no significant differences in global decay ...
-
(2007)Initial states in incompressible two-dimensional magnetohydrodynamics that are known to lead to strong current sheets and (laminar) magnetic reconnection are modified by the addition of small-scale turbulent perturbations ... -
(2001)With supervisory control theory it is possible to describe controllers which influence the behaviour of a system by disabling controllable events. But sometimes it is desirable to have a controller which not only disables ... -
(University of Waikato, Department of Computer Science, 2011)Generalised nonblocking is a property of discrete-event systems which verifies liveness. It was introduced to overcome the weaknesses of standard nonblocking. Verifying generalised nonblocking of real-world models often ... -
(University of Waikato, Department of Computer Science, 2010)Many mobile devices have a density of services, many of which are context or location-aware. To function, many of these services have to collaborate with other services, which may be located in many different places and ... -
(Springer, 2002)Flexible digital library systems need to be able to accept, or “import,” documents and metadata in a variety of forms, and associate metadata with the appropriate documents. This paper analyzes the requirements of the ...
-
(IEEE, 2012)This paper describes a simulation to establish the extent to which reliance on non-dispatchable energy sources, particularly wind generation, could in the future be extended beyond accepted norms, by utilizing the distributed ...

(2009)We propose two new improvements for bagging methods on evolving data streams. Recently, two new variants of Bagging were proposed: ADWIN Bagging and Adaptive-Size Hoeffding Tree (ASHT) Bagging. ASHT Bagging uses trees of ... -
(IEEE, 2010)Bag-of-Words (BOW) models have recently become popular for the task of object recognition, owing to their good performance and simplicity. Much work has been proposed over the years to improve the BOW model, where the ... -
(Elsevier Science B.V., 1999)Browsing accounts for much of people's interaction with digital libraries, but it is poorly supported by standard search engines. Conventional systems often operate at the wrong level, indexing words when people think in ... -
(2008)A novel method of face gender classifier construction is proposed and evaluated. Previously, researchers have assumed that a computationally expensive face alignment step (in which the face image is transformed so that ... -
(Springer, Berlin, 2006)Bagging is an ensemble learning method that has proved to be a useful tool in the arsenal of machine learning practitioners. Commonly applied in conjunction with decision tree learners to build an ensemble of decision ...
-
(University of Waikato, Department of Computer Science, 2011)Fitnesse and FIT [5] allow systems tests to be written by non-programmers using a Wiki or HTML style of input. However, there is little support for syntactic and semantic checks as the tests are being designed. This paper ... -
(2001)As the WWW continues to grow, providing adequate bandwidth to countries remote from the geographic and topological center of the network, such as those in the Asia/Pacific, becomes more and more difficult. To meet the ...
