Harmony Search Algorithm (HSA) is an evolutionary algorithm which mimics the process of music improvisation to obtain a nice harmony. The algorithm has been successfully applied to solve optimization problems in different domains. A significant shortcoming of the algorithm is inadequate exploitation when trying to solve complex problems. The algorithm relies on three operators for performing improvisation: memory consideration, pitch adjustment, and random consideration. In order to improve algorithm efficiency, we use roulette wheel and tournament selection in memory consideration, replace (...) the pitch adjustment and random consideration with a modified polynomial mutation, and enhance the obtained new harmony with a modified β-hill climbing algorithm. Such modification can help to maintain the diversity and enhance the convergence speed of the modified HS algorithm. β-hill climbing is a recently introduced local search algorithm that is able to effectively solve different optimization problems. β-hill climbing is utilized in the modified HS algorithm as a local search technique to improve the generated solution by HS. Two algorithms are proposed: the first one is called PHSβ–HC and the second one is called Imp. PHSβ–HC. The two algorithms are evaluated using 13 global optimization classical benchmark function with various ranges and complexities. The proposed algorithms are compared against five other HSA using the same test functions. Using Friedman test, the two proposed algorithms ranked 2nd (Imp. PHSβ–HC) and 3rd (PHSβ–HC). Furthermore, the two proposed algorithms are compared against four versions of particle swarm optimization (PSO). The results show that the proposed PHSβ–HC algorithm generates the best results for three test functions. In addition, the proposed Imp. PHSβ–HC algorithm is able to overcome the other algorithms for two test functions. Finally, the two proposed algorithms are compared with four variations of differential evolution (DE). The proposed PHSβ–HC algorithm produces the best results for three test functions, and the proposed Imp. PHSβ–HC algorithm outperforms the other algorithms for two test functions. In a nutshell, the two modified HSA are considered as an efficient extension to HSA which can be used to solve several optimization applications in the future. (shrink)

This article introduces a framework for enhancing underwater images using the particle swarm optimization algorithm. A pre-processing step is introduced to reduce the absorbing and scattering effects of water before applying a filter based on this algorithm to enhance the image. The quality of enhanced images is quantitatively assessed by applying the framework on a dataset of underwater images. The obtained results show a considerable improvement.

Recent rapid advances in Artificial Intelligence and Machine Learning have raised many questions about the regulatory and governance mechanisms for autonomous machines. Many commentators, scholars, and policy-makers now call for ensuring that algorithms governing our lives are transparent, fair, and accountable. Here, I propose a conceptual framework for the regulation of AI and algorithmic systems. I argue that we need tools to program, debug and maintain an algorithmic social contract, a pact between various human stakeholders, mediated by machines. To achieve (...) this, we can adapt the concept of human-in-the-loop from the fields of modeling and simulation, and interactive machine learning. In particular, I propose an agenda I call society-in-the-loop, which combines the HITL control paradigm with mechanisms for negotiating the values of various stakeholders affected by AI systems, and monitoring compliance with the agreement. In short, ‘SITL = HITL + Social Contract.’. (shrink)

Cybernetics, or self-governance of animal and machine, requires the ability to sense the world and to act on it in an appropriate manner. Likewise, self-governance of a human society requires groups of people to collectively sense and act on their environment. I argue that the evolution of political systems is characterized by a series of innovations that attempt to solve two ‘scalability’ problems: scaling up a group’s ability to make sense of an increasingly complex world, and to cooperate in increasingly (...) larger groups. I then explore some recent efforts toward using the Internet and social media to provide alternative means for addressing these scalability challenges, under the banners of crowdsourcing and computer-supported argumentation. I present some lessons from those efforts about the limits of technology, and the research directions more likely to bear fruit. (shrink)

Argumentation is a very fertile area of research in Artificial Intelligence, and various semantics have been developed to predict when an argument can be accepted, depending on the abstract structure of its defeaters and defenders. When these semantics make conflicting predictions, theoretical arbitration typically relies on ad hoc examples and normative intuition about what prediction ought to be the correct one. We advocate a complementary, descriptive-experimental method, based on the collection of behavioral data about the way human reasoners handle these (...) critical cases. We report two studies applying this method to the case of reinstatement (both in its simple and floating forms). Results speak for the cognitive plausibility of reinstatement and yet show that it does not yield the full expected recovery of the attacked argument. Furthermore, results show that floating reinstatement yields comparable effects to that of simple reinstatement, thus arguing in favor of preferred argumentation semantics, rather than grounded argumentation semantics. Besides their theoretical value for validating and inspiring argumentation semantics, these results have applied value for developing artificial agents meant to argue with human users. (shrink)

The primary objective of this research is to examine the potential influence of environmental, social, and governance (ESG) disclosure on cash holdings. Additionally, the study explores the role of earnings management (EM) practices as a mediating factor in this relationship. The sample comprises 797 companies listed on financial markets across 19 European countries, and the data spans from 2013 to 2019. The outcomes indicate a significant negative correlation between ESG disclosure and cash holdings, implying that ESG performance can be used (...) by management to resolve disputes with stakeholders. The outcomes further indicate that the existence of EM practices partially mediates the link between ESG disclosure and cash holdings. Moreover, they are robust by substitute cash holdings specification, three distinct initiatives of ESG disclosure (i.e., environment, social, and governance), and a two-stage least squares assessment. Therefore, the findings document that nonfinancial reporting in the form of ESG disclosure can assist in controlling agency conflict, leading to better valuations of company performance by stakeholders.

The contemporary Qur’anic studies have been marked by amazing development. Various methods and approaches to understand the Qur’an are offered by the scholars. One of the prominent figures in this field is Nashr Hamid Abu Zayd. Nasr Hamid Abu Zayd (1943–2010 M) is a highly controversial contemporary thinker. He is an Egyptian scholar who is accused of being apostate, because of his theory of qur’anic hermeneutic (the textual of Qur’an). This is reflected in his stances towards contemporary religious discourse and (...) the approach to reading religious texts, especially the Quran, which requires reading according to a hermeneutic mechanism. His books ‘Naqd al-Khitab al-Dini (Criticism of Religious Discourse)’ and ‘Al-Takfir fi Zaman al-Takfir (Thinking in the Time of Atonement)’ caused a great uproar in the early nineties of the last century. Abu Zayd was accused of criticising atheists because of their stances on the text. Therefore, this study aimed to discuss Abu Zayd’s position on contemporary religious discourse and his new approach to reading religious texts, and also aims to discuss why Abu Zayd’s theory has been string up Islamic world and ending by his expulsive from his native country. To deal with this problem, this article discusses Abd Zayd’s biography and some cultural framework of his people. The methodology of Qur’anic hermeneutic is the least his. Having examined the topic, the author finds that Abu Zayd believes that modem literary theory and criticism denote the way to understand and interpret the Qur’an ‘objectively’. The contribution of this research is discussing Abu Zayd’s contemporary religious discourse and his new approach to reading religious texts. Contribution: The contribution of this research is discussing Abu Zayd’s contemporary religious discourse and his new approach to reading religious texts. (shrink)

This article aimed to highlight how polemic between Muslims and Christians on halal tourism is discussed in Indonesia. The study concerned three research questions: How do Christians view halal tourism? Is the halal tourism a term that has the potential to build segregation according to the Christians’ perspective? How do Muslims respond to Christians on halal tourism? By reviewing related literature and conducting interviews and analysis using reception theory, this study reached the following conclusions. Firstly, Christian religious figures view on (...) halal tourism by varied characters: realistic, substantial and critical. Secondly, for those with oppositional views, they emphatically said that the term halal tourism had the potential to build segregation. Meanwhile, in a negotiation position, the main substantial one is still open minded for discussion if there is a concept that is formally more inclusive and from the material side representing the common will even though it was originally a will of a particular group. Thirdly, Muslims, as represented in the Indonesian Ulema Council (MUI), perceive that halal tourism does not interfere with other religious beliefs, but it has an economic value for the country.Contribution: Practically, this article contributed to opening opportunities for halal tourism to be recognised by all elements in a multi-religious society. Differences in potential reception occur because the sender of the message and the recipient of the message have basic assumptions according to their respective contexts. (shrink)
