    Recently, there has been much research into effective representation and analysis of uncertainty in human responses, with applications in cyber-security, forest and wildlife management, and product development, to name a few. Most of this research has focused on representing the response uncertainty as intervals, e.g., “I give the movie between 2 and 4 stars.” In this paper, we extend upon the model-based interval agreement approach (IAA) for combining interval data into fuzzy sets and propose the efficient IAA (eIAA) algorithm, which enables efficient representation of and operation on the fuzzy sets produced by IAA (and other interval-based approaches, for that matter). We develop methods for efficiently modeling, representing, and aggregating both crisp and uncertain interval data (where the interval endpoints are intervals themselves). These intervals are assumed to be collected from individual or multiple survey respondents over single or repeated surveys; although, without loss of generality, the approaches put forth in this paper could be used for any interval-based data where representation and analysis is desired. The proposed method is designed to minimize loss of information when transferring the interval-based data into fuzzy set models and then when projecting onto a compressed set of basis functions. We provide full details of eIAA and demonstrate it on real-world and synthetic data

    The Research Institute in Science of Cyber Security (RISCS) takes an evidence-based and interdisciplinary approach to addressing cyber security challenges. By providing a platform for the exchange of ideas, problems and research solutions between academia, industry, and both the UK and international policy communities, RISCS promotes and supports the development of scientific approaches to cyber security. Central to the RISCS agenda is the application of bodies of knowledge to stimulate a transition from ‘common practice’ to ‘evidence-based best practice’ in cyber security. Recognising that cyber security is a contested concept, RISCS operates within a national and international cyber security framework to establish a coherent set of research principles. These principles focus on the deployment of scientific methods and the gathering of evidence to produce sound interventions and responses to cyber security challenges. We actively seek to maximise collaboration amongst our diverse community through a culture of open publication, sharing and expanding our network. Through this collaboration, RISCS develops techniques that enable communities to anticipate emergent cyber security issues from public policy, social practice and technological perspectives. Our end goal is to deliver a world-class portfolio of activity and research findings that maximises the value of social, political and economic research into cyber security and which results in a set of scientifically based options that individuals, institutions and nation states can use to respond to imminent and long term cyber security challenges

Most of this research has focused on representing the response uncertainty as intervals, e.g., “I give the movie between 2 and 4 stars.” In this paper, we extend upon the model-based interval agreement approach (lAA) for combining interval data into fuzzy sets and propose the efficient IAA (eIAA) algorithm, which enables efficient representation of and operation on the fuzzy sets produced by IAA (and other interval-based approaches, for that matter).
