In this paper we study a new restriction of the PAC learning framework, in which each label class is handled by an unsupervised learner that aims to fit an appropriate probability distribution to its own data. A hypothesis is derived by choosing, for any unlabeled instance, the label whose...

Based on multiple-case research, this paper develops a model of strategic information systems (IS) investment in small and medium-sized enterprises (SMEs). IS investment is modelled as a function of an SME's strategic context as defined by its strategic focus, i.e. cost reduction versus value...

The purpose of this thesis is to introduce a new broad approach to computing - Empirical Modelling (EM) - and to propose a way of applying this approach for system development so as to avoid the limitations of conventional approaches and integrate system development with business process...

For businesses planning interactions online, particularly using Web services, managing risks and accommodating each other's varying business-level security requirements is a complex but critical issue during development. Literature suggests numerous reasons that prohibit the simplistic adoption,...

This article examines the interdependency of population-level adaptation (evolution) and individual-level adaptation (learning). More specifically, we assume a trade-off between the two means of adaptation, that is, a higher individual-level adaptation can only be achieved with a reduced...

This paper presents a model, which allows managers to identify the influence of their decisions to the potential innovation activity of the firm by simulation. Systems Thinking methodology has been used to understand the framework of innovation systems and to design and run the simulation model....

This paper is concerned with optimizing financial programs through the use of performance models to promote the best use of available computational resources, The work necessarily focuses on run-time optimization, where a performance model of the program is combined with knowledge of run-time...

Business Process Reengineering (BPR) was developed as a new idea which, it was suggested, could revolutionise the corporation and give it a major competitive advantage by simplifying key business processes and utilising information technology to secure cross-functional communication and focus on...

A conditional simulation technique has previously been presented for variance reduction when estimating rail probabilities. particularly extreme ones. for a wide class of moving-average processes. Here. ve generalize the technique from continuous ro discrete random variables. Two distinct...

Business Process Reengineering (BPR) was developed as a new idea which, if was suggested, would revolutionise the corporation and give it a major competitive advantage, Rather than continue the debate about whether BPR is 'good' or 'bad', the focus here is on understanding how the concept 'BPR',...
