    Building an ANFIS-based Decision Support System for Regional Growth: The Case of European Regions

    This paper proposes a Decision Support System that can provide European policy makers with systematic guidance in allocating and prioritizing scant public resources. We do so by taking the stance of the Smart Specialisation Strategies which aim at consolidating the regional strengths and make effective and efficient use of public investment in R&D. By applying the ANFIS method we were able to understand how – and to what extent – the competitiveness drivers promoted technological development and how the latter contributes to the economic growth of European regions. We used socio-economic, spatial, and patent-based data to train, test and validate the models. What emerges is that an increase of R&D investments enhances the regional employment rate and the number of patents per capita; in turn, by taking into account the several combinations of specialization and diversification indicators, this leads to an increase of the regional GDP

    Quantum Monte Carlo simulations for estimating FOREX markets: A speculative attacks experience

    The foreign exchange markets, renowned as the largest financial markets globally, also stand out as one of the most intricate due to their substantial volatility, nonlinearity, and irregular nature. Owing to these challenging attributes, various research endeavors have been undertaken to effectively forecast future currency prices in foreign exchange with precision. The studies performed have built models utilizing statistical methods, being the Monte Carlo algorithm the most popular. In this study, we propose to apply Auxiliary-Field Quantum Monte Carlo to increase the precision of the FOREX markets models from different sample sizes to test simulations in different stress contexts. Our findings reveal that the implementation of Auxiliary-Field Quantum Monte Carlo significantly enhances the accuracy of these models, as evidenced by the minimal error and consistent estimations achieved in the FOREX market. This research holds valuable implications for both the general public and financial institutions, empowering them to effectively anticipate significant volatility in exchange rate trends and the associated risks. These insights provide crucial guidance for future decision-making processes

    ICICS-2020 is the third conference initiated by the School of Electronics and Electrical Engineering at Lovely Professional University that explored recent innovations of researchers working for the development of smart and green technologies in the fields of Energy, Electronics, Communications, Computers, and Control. ICICS provides innovators to identify new opportunities for the social and economic benefits of society.  This conference bridges the gap between academics and R&D institutions, social visionaries, and experts from all strata of society to present their ongoing research activities and foster research relations between them. It provides opportunities for the exchange of new ideas, applications, and experiences in the field of smart technologies and finding global partners for future collaboration. The ICICS-2020 was conducted in two broad categories, Intelligent Circuits & Intelligent Systems and Emerging Technologies in Electrical Engineering

    THE USE OF ARTIFICIAL NEURAL NETWORKS AS A STRATEGY FOR FORECASTING PRICES IN THE CONTEXT OF AGRIBUSINESS

    No full text
    This paper presents an analysis of the use of artificial neural networks as a strategy for forecasting prices in the context of agribusiness. For this purpose, data were adopted from EMATER/RS (1992-2006) on four specific commodities: soybean, live cattle, corn, and wheat. The methodology adopted during the research followed the steps shown in Hair et al. (2005), using neural network perception. The data discussed demonstrate the possibility of using neural networks as a strategy for predicting the price of agricultural commodities in future markets. However, one should pay attention to the common cognitive bias in the process of decision making, as it is believed that a significant contribution to academia lies there, as well as a starting point for improving management decisions in rural business.Este artigo apresenta uma análise do uso de redes neurais artificiais como estratégia de previsão de preços no contexto do agronegócio. Para tanto, adotou-se como pano de fundo dados da Emater/RS (1992-2006) a respeito de quatro commodities específicas: soja, boi gordo, milho e trigo. A metodologia adotada durante a pesquisa seguiu os passos apresentados em Hair et al. (2005), utilizando-se o modelo de rede neural perception. Os dados trabalhados evidenciam a possibilidade do uso de redes neurais como uma estratégia de precificação dos preços de commodities agrícolas em mercados futuros. Embora deva-se ter atenção aos vieses cognitivos frequentes nos processos de tomada de decisão, acredita-se que há uma contribuição significativa à academia, bem como pode ser um ponto de partida para a melhoria nas decisões dos gestores rurais

    Horizontal and Vertical Rule Bases Method in Fuzzy Controllers

    Get PDF
    Concept of horizontal and vertical rule bases is introduced. Using this method enables the designers to look for main behaviors of system and describes them with greater approximations. The rules which describe the system in first stage are called horizontal rule base. In the second stage, the designer modulates the obtained surface by describing needed changes on first surface for handling real behaviors of system. The rules used in the second stage are called vertical rule base. Horizontal and vertical rule bases method has a great roll in easing of extracting the optimum control surface by using too lesser rules than traditional fuzzy systems. This research involves with control of a system with high nonlinearity and in difficulty to model it with classical methods. As a case study for testing proposed method in real condition, the designed controller is applied to steaming room with uncertain data and variable parameters. A comparison between PID and traditional fuzzy counterpart and our proposed system shows that our proposed system outperforms PID and traditional fuzzy systems in point of view of number of valve switching and better surface following. The evaluations have done both with model simulation and DSP implementation
