Abstract
Purpose
This paper aims to utilize machine learning and soft computing to propose a new method of rough sets using deep learning architecture for many real-world applications.
Design/methodology/approach
The objective of this work is to propose a model for deep rough set theory that uses more than decision table and approximating these tables to a classification system, i.e. the paper propose a novel framework of deep learning based on multi-decision tables.
Findings
The paper tries to coordinate the local properties of individual decision table to provide an appropriate global decision from the system.
Research limitations/implications
The rough set learning assumes the existence of a single decision table, whereas real-world decision problem implies several decisions with several different decision tables. The new proposed model can handle multi-decision tables.
Practical implications
The proposed classification model is implemented on social networks with preferred features which are freely distribute as social entities with accuracy around 91 per cent.
Social implications
The deep learning using rough sets theory simulate the way of brain thinking and can solve the problem of existence of different information about same problem in different decision systems
Originality/value

Abstract
Purpose
The rough set concept is a new mathematical approach to imprecision, vagueness and uncertainty. This paper introduces the emergent computational paradigm and discusses its applicability and potential in rough set theory.
Design/methodology/approach
A conceptual discussion and approach are taken.
Findings
For accepting a system is displaying an emergent behavior, the system should be constructed by describing local elementary interactions between components in different ways of describing global behavior and properties of the running system over a period of time. The proposals of an emergent computation structure for implementing basic rough sets theory operators are also given in this paper.
Originality/value
The results will have an important impact on the development of new methods for knowledge discovery in databases, in particular for development of algorithmic methods for pattern extraction from data.

Abstract
A methodology for using rough set for preference modeling in decision problem is presented in this paper; where we will introduce a new approach for deriving knowledge rules from database based on rough set combined with genetic programming. Genetic programming belongs to the most new techniques in applications of artificial intelligence. Rough set theory, which emerged about 20 years back, is nowadays a rapidly developing branch of artificial intelligence and soft computing. At the first glance, the two methodologies that we discuss are not in common. Rough set construct is the representation of knowledge in terms of attributes, semantic decision rules, etc. On the contrary, genetic programming attempts to automatically create computer programs from a high‐level statement of the problem requirements. But, in spite of these differences, it is interesting to try to incorporate both the approaches into a combined system. The challenge is to obtain as much as possible from this association.

Abstract
Purpose
Nature is the single and most complex system that has been always studied, and no one can compete Mother Nature, but we can learn from her, by many new methodologies through biology. The paper aims to discuss this issue.
Design/methodology/approach
In this paper, being inspired by the mechanism through which our Mother Nature handling human taste, a proposed model for clustering and classification hand gesture is introduced based on human taste controlling strategy.
Findings
The model can extract information from measurement data and handling it as the structure of tongue and the nervous systems of human taste recognition.
Originality/value
The efficiency of proposed model is demonstrated experimentally on classifying the sign language data set; in the high recognition accuracy obtained for numbers of ASL was 95.52 percent.

Abstract
It has recently been shown that an approach termed emergence system has gained popularity in a variety of fields, however, emergent computation in decentralized spatially extended systems, such as in cellular automata, is still not well understood. To accept that a system is displaying emergent behavior, the system should be constructed by describing local elementary interactions between components. This is achieved in a different way by describing global behavior and properties of the running system over a period of time. This paper introduces the emergent computational paradigm, and discusses its theoretical formulation using a new general model of cellular automata. We have also developed a technique to study the structure of the state transition of cellular automata in the limit of large system size.

Abstract
Purpose
Media has always been used as a key manipulator of public agendas, political beliefs and individuals’ attitudes. The purpose of this study is to investigate the impact of three adaptive media strategies on the pattern and dynamics of potential crowds.
Design/methodology/approach
An agent-based approach is used to simulate the three adaptive media strategies on the pattern and dynamics of potential crowds. During the experiments, the media broadcast is intensified to gather momentum for crowd movements or is lessened to maintain the budget.
Findings
The results show that a slight change in the media management strategy could lead to a radical different impact on the crowd dynamics. The results also show that a quite smart media strategy could outperform a strategy with an unlimited budget. Finally, the structure of the society shows a significant influence on the crowd dynamics than it could be inferred.
Originality/value
The model presents an explanatory toolkit for the crowd complexity. The results provide deep insights into the crowd formation and a basis for understanding the influence of media and the impact of its strategies on the crowd dynamics.

Abstract
Purpose
The growing popularity of mobile technology has led governments across the world to develop mobile business models and encouraged the transition from the electronic government (e-government) to the mobile government (m-government). However, only a small amount of data is available regarding m-government implementation in developing countries and users’ behavioural intentions (BIs) with respect to the utilization of such services. To address this issue, this study attempts to identify factors that affect m-government acceptance among citizens of the United Arab Emirates (UAE). This study aims to examine the relationships between m-government service characteristics and m-government technology characteristics by analysing their perceived ease-of-use, perceived usefulness, user attitudes towards m-government usage and corresponding BIs with respect to utilization of m-government services.
Design/methodology/approach
This study is based on a quantitative survey conducted among 326 users of m-government services in the UAE. The responses were tabulated on a five-point Likert scale. Structural equation modelling was used to evaluate the performance of the proposed model and verify the hypothesized relationships between its constructs.
Findings
Overall, the research findings indicate that: users’ intention to use m-government applications has three determinants – attitude towards m-government use, m-government ease of use and m-government usefulness; m-government usefulness and ease of use have a significant influence on user attitudes towards m-government; and perceived ease of use of the service, currency of the services, the accuracy of the provided information, the security concerns associated with the utilization of the m-government services, trust in the m-government services and the risks perceived in using the m-Government service are antecedents of users’ perceptions of the m-government services.
Originality/value
This study has improved our understanding of the critical mobile technology factors that are needed to improve user acceptance of m-government services. The study presents important implications for both theory and practice.

Abstract
Purpose
Earnings quality is of great concern to corporate stakeholders, including capital providers in international markets with widely varying regulatory pedigrees and ownership patterns. This paper aims to examine the association between the cost of equity capital and earnings quality, contextualised via tests that incorporate the potential for moderating effects around institutional settings. The analysis focuses on and compares evidence relating to (common law) UK/US firms and (civil law) German firms over the period 2005–2018 and seeks to identify whether, given institutional dissimilarities, significant differences exist between the two settings.
Design/methodology/approach
First, the authors undertake a review of the extant literature on the link between earnings quality and the cost of capital. Second, using a sample of 948 listed companies from the USA, the UK and Germany over the period 2005 to 2018, the authors estimate four implied cost of equity capital proxies. The relationship between companies’ cost of equity capital and their earnings quality is then investigated.
Findings
Consistent with theoretical reasoning and prior empirical analyses, the authors find a statistically negative association between earnings quality, evidenced by information relating to accruals and the cost of equity capital. However, when they extend the analysis by investigating the combined effect of institutional ownership and earnings quality on financing cost, the impact – while negative overall – is found to vary across legal backdrops.
Research limitations/implications
This paper uses institutional ownership as a mediating variable in the association between earnings quality and the cost of equity capital, but this is not intended to suggest that other measures may be of relevance here and additional research might usefully expand the analysis to incorporate other forms of ownership including state and foreign bases. Second, and suggestive of another avenue for developing the work presented in the study, the authors have used accrual measures of earnings quality.
Practical implications
The results are shown to provide potentially important insights for policymakers, creditors and investors about the consequences of earnings quality variability. The results should be of interest to firms seeking to reduce their financing costs and retain financial viability in the wake of the impact of the Covid-19 pandemic.
Originality/value
The reported findings extends the single-country results of Eliwa et al. (2016) for the UK firms and Francis et al. (2005) for the USA, whereby both reported that the cost of equity capital is negatively associated with earnings quality attributes. Second, in a further increment to the extant literature (particularly Francis et al., 2005 and Eliwa et al., 2016), the authors find the effect of institutional ownership to be influential, with a significantly positive impact on the association between earnings quality and the cost of equity capital, suggesting in turn that institutional ownership can improve firms’ ability to secure cheaper funding by virtue of robust monitoring. While this result holds for the whole sample (the USA, the UK and Germany), country-level analysis shows that the result holds only for the common law countries (the UK and the USA) and not for Germany, consistent with the notion that extant legal systems are a determining factor in this context. This novel finding points to a role for institutional investors in watching and improving the quality of financial reports that are valued by the market in its price formation activity.
