In recent times, there has been considerable interest in the potential advantages of decentralised “Edge” organisations. In order to investigate the potential costs and benefits of such organisational structures for Command and Control (C2), we have combined organisational simulation with a novel tree rewiring process that creates a spectrum of organisational structures ranging from a pure hier...

Gaussian comparison theorems are useful tools in probability theory; they are essential ingredients in the classical proofs of many results in empirical processes and extreme value theory. More recently, they have been used extensively in the analysis of underdetermined linear inverse problems. A prominent role in the study of those problems is played by Gordon’s Gaussian min-max theorem. It ha...

High utility itemset mining (HUIM) is a new emerging field in data mining which has gained growing interest due to its various applications. The goal of this problem is to discover all itemsets whose utility exceeds minimum threshold. The basic HUIM problem does not consider length of itemsets in its utility measurement and utility values tend to become higher for itemsets containing more items...

Utility episode mining has emerged as an interesting and challenging research topic in data mining. It finds applications in anomaly detection, biomedical data analysis, predicting stock trends etc. The number of high-utility episodes that can be extracted from a sequence depends upon the value of minimum utility threshold. It is often difficult for a user to find a suitable threshold value whi...

We introduce a solution concept for cooperative game with transferable utility and a coalition structure that is proportional for two-player games. Our value is obtained from generalizing a proportional value for cooperative game with transferable utility (Ortmann, 2000) in a way that parallels the extension of the Shapley value to the Owen value. We provide two characterizations of our solutio...

Although rewards are physical stimuli and objects, their value for survival and reproduction is subjective. The phasic, neurophysiological and voltammetric dopamine reward prediction error response signals subjective reward value. The signal incorporates crucial reward aspects such as amount, probability, type, risk, delay and effort. Differences of dopamine release dynamics with temporal delay...

This paper develops a multiattribute preference ranking rule in the context of utility robustness. A nonparametric perturbation of a given additive reference utility function is specified to solve the problem of ambiguity and inconsistency in utility assessments, while preserving the additive structure and the decision maker’s risk preference under each criterion. A concept of robust preference...

The aim of this paper is to develop a conceptual framework for studying the use of geo-information and associated technology in government. We first review how geo-information, geo-information technology and people—notions central to geo-information use—are conceptualized in the literature and show that authors view these notions through two contrasting lenses, a market and a polis lens. We the...

We consider the problem of designing (perhaps massively distributed) collectives of computational processes to maximize a provided “world” utility function. We consider this problem when the behavior of each process in the collective can be cast as striving to maximize its own payoff utility function. For such cases the central design issue is how to initialize/update those payoff utility funct...
