On developing robust models for favourability analysis : Model choice, feature sets and imbalanced data
(2012)Locating documents carrying positive or negative favourability is an important application within media analysis. This article presents some empirical results on the challenges facing a machine-learning approach to this ... -
On Drive-by-Download Attacks and Malware Classification
(North East Wales Institute, 2013-09) -
On finite presentability of Bruck-Reilly extensions of a monoid with respect to an endomorphism and its powers.
(2007-09)Let M be a monoid and let θ be an endomorphism of M. We prove that if the Bruck–Reilly extension BR(M, θ) is finitely presented, then the Bruck–Reilly extension BR(M, θm) is also finitely presented for all m ⩾ 1 -
On fuzzy frontiers and fragmented foundations : some reflections on the original and new institutional economics
(2014-12-31)These reflections are prompted by the papers by Ménard (2014) and Ménard and Shirley (2014). Their essays centre on the path-breaking contributions to the 'new institutional economics' (NIE) by Ronald Coase, Douglass North ... -
On Improving the Calibration of Millimetre and Submillimetre Photometry at the James Clerk Maxwell Telescope / JCMT
(1994-10-01)A method is described for deriving the atmospheric extinction coefficients corresponding to the passband filters in the James Clerk Maxwell Telescope (JCMT) common-user photometer. This method takes advantage of the ... -
On information-optimal scripting of actions
(MIT Press, 2019-07)Animals and humans encounter many tasks which permit ritualized behaviours, essentially fixed action sequences or “scripts”, similar to options known from Reinforcement Learning, but proceeding without intermediate decisions. ... -
On Initializations for the Minkowski Weighted K-Means
(Springer Nature, 2012)Minkowski Weighted K-Means is a variant of K-Means set in the Minkowski space, automatically computing weights for features at each cluster. As a variant of K-Means, its accuracy heavily depends on the initial centroids ... -
On Instance Weighted Clustering Ensembles
(2023-10-04)Ensemble clustering is a technique which combines multipleclustering results, and instance weighting is a technique which highlightsimportant instances in a dataset. Both techniques are known to enhanceclustering performance ... -
On IP and secrecy : The relevance of intellectual property rights to design-led start-up businesses
(2013-08-30)This paper will unveil how design-led start-up businesses can enhance their growth potential through securing exclusive access to intellectual property (IP). Many design-led start-up companies commonly see themselves ... -
On IP and secrecy Management for Innovation : the relevance of intellectual property rights to design-led start-up businesses
(2013-09-04)In their book, ‘The Smart Entrepreneur’, Clarysse and Kiefer claim that ‘Patents are particularly important when your business is not close to market, because the exclusivity afforded by a solid patent can buy you some ... -
On kappa-deformation and triangular quasibialgebra structure
(2008-07-17)We show that, up to terms of order 1/kappa^5, the kappa-deformed Poincare algebra can be endowed with a triangular quasibialgebra structure. The universal R matrix and coassociator are given explicitly to the first few ... -
On Maltsev digraphs
(2011)We study digraphs preserved by a Maltsev operation, Maltsev digraphs. We show that these digraphs retract either onto a directed path or to the disjoint union of directed cycles, showing that the constraint satisfaction ... -
On Maltsev Digraphs
(2015-02-25)We study digraphs preserved by a Maltsev operation: Maltsev digraphs. We show that these digraphs retract either onto a directed path or to the disjoint union of directed cycles, showing in this way that the constraint ... -
On Method: the problem of objectivity
(Staffordshire University Press, 2000)In this paper I shall criticise the notion of objectivity in design research methodology. I shall argue that the requirement for such objectivity is either implicit in the phrasing of research degree regulations, or is ... -
On multi-objective optimization of geometry of staggered herringbone micromixer
(2009-07)A design methodology for micromixers is presented which systematically integrates computational fluid dynamics (CFD) with an optimization methodology based on the use of design of experiments (DOE), function approximation ... -
On Partitional Clustering of Malware
(2012-07)In this paper we fully describe a novel clustering method for malware, from the transformation of data into a manipulable standardised data matrix, finding the number of clusters until the clustering itself including ... -
On Power and Control Systems of the Multibody Advanced Airship for Transport
(2013)The concept of the Multibody Advanced Airship for Transport (MAAT) is presented. The power, propulsion and control systems of the airship are discussed. The energy required for operation of this airship is supplied by a ...
