The many-to-many location-routing problem

In this paper the many to many location routing problem is introduced, and its relationship to various problems in distribution management is emphasised. Useful mathematical formulations which can be easily extended to cater for other related problems are produced. Techniques for tackling this complex distribution problem are also outlined.

A robust approach to subsequence matching

In terms of a general time theory which addresses time-elements as typed point-based intervals, a formal characterization of time-series and state-sequences is introduced. Based on this framework, the subsequence matching problem is specially tackled by means of being transferred into bipartite graph matching problem. Then a hybrid similarity model with high tolerance of inversion, crossover and noise is proposed for matching the corresponding bipartite graphs involving both temporal and non-temporal measurements. Experimental results on reconstructed time-series data from UCI KDD Archive demonstrate that such an approach is more effective comparing with the traditional similarity model based algorithms, promising robust techniques for lager time-series databases and real-life applications such as Content-based Video Retrieval (CBVR), etc.

A critical examination of node-similarity based graph matching algorithms

In this paper, we shall critically examine a special class of graph matching algorithms that follow the approach of node-similarity measurement. A high-level algorithm framework, namely node-similarity graph matching framework (NSGM framework), is proposed, from which, many existing graph matching algorithms can be subsumed, including the eigen-decomposition method of Umeyama, the polynomial-transformation method of Almohamad, the hubs and authorities method of Kleinberg, and the kronecker product successive projection methods of Wyk, etc. In addition, improved algorithms can be developed from the NSGM framework with respects to the corresponding results in graph theory. As the observation, it is pointed out that, in general, any algorithm which can be subsumed from NSGM framework fails to work well for graphs with non-trivial auto-isomorphism structure.

From ALIBI to COLUMBUS. The long march to self-aware, reflective computational models of humor

One thing is (a) to develop a system that handles some task to one's satisfaction, and also has a universally recognized myrthful side to its output. Another thing is (b) to provide an analysis of why you are getting such a byproduct. Yet another thing is (c) to develop a model that incorporates reflection about some phenomenon in humor for its own sake. This paper selects for discussion especially Alibi, going on to describe the preliminaries of Columbus. The former, which fits in (a), is a planner with an explanatory capability. It invents pretexts. It's no legal defense, but it is relevant to evidential thinking in AI & Law. Some of the output pretext are myrthful. Not in the sense they are silly: they are not. A key factor seems to be the very alacrity at explaining out detail after detail of globally damning evidence. I attempt a reanalysis of Alibi in respect of (b). As to Columbus, it fits instead in (c). We introduce here the basics of this (unimplemented) model, developed to account for a sample text in parody.

New public management of Higher education, Foucault and power

The theory of New Public Management (NPM) suggest that one of the features of advanced liberal rule is the tendency to define social, economic and political issues as problems to be solved through management. This paper argues that the restructuring of Higher Education (HE) in many Western countries since the 1980s has involved a shift from an emphasis on administration and policy to one of its efficient management. Utilising Foucault’s concept of governmentality rather than the liberal discourse of management as a politically neutral technology, managerialism can be seen as a newly emergent and increasingly rationalised disciplinary regime of governmentalising practices in advanced liberalism. As such the contemporary University as an institution governed by NPM can be demonstrated to have emerged not as the direct outcome of democratic policies that have rationalised its activities (so that the emancipatory aims of personal development, an educated workforce and of true research can be fully realised), nor can it be understood as the instrument through which individuals or self-realising classes are defeated through the calculations of the state acting on behalf of economic interests, rather it can be seen as the contingent and intractable outcome of the complex power/knowledge relations of advanced liberalism. I analyse the interlocking of the ‘tutor-subject’ and ‘student-subject’ as a local enacting of policy discourse informed by the NPM of HE that reshapes subjectivity and retunes the relationship between tutor and student. I put forward suggestions for how resistance to these new modes of disciplinary subjectification can be enacted.
