الگوریتمهای موجود برای آموزش سیستم استنتاج فازی- عصبی تطبیقی (ANFIS) باوجود کاربرد فراوان، نقایصی همچون بهدامافتادن در بهینۀ محلی دارند. در پژوهش حاضر، کاربرد الگوریتمهای بهینهسازی ژنتیک (GA)، ازدحام ذرات (PSO)، کلونی مورچگان برای محیطهای پیوسته (ACOR) و تکامل تفاضلی (DE)، در توسعه و بهبود عملکرد ANFIS بررسی شد. بهعنوان مطالعۀ موردی، بیشترین دمای ماهانۀ شهر اصفهان در بازۀ زمانی 64 س...
Horizontal Directional Drilling (HDD) is extensively used in geothechnical engineering. In a variety of conditions it is essential to predict the torque required for performing the reaming operation. Nevertheless, there is presently not a convenient method to accomplish this task. To overcome this problem, in this research, the application of computational intelligence methods for data analysis...
One of the most significant and effective criteria in the process of cutting dimensional rocks using the gang saw is the maximum energy consumption rate of the machine, and its accurate prediction and estimation can help designers and owners of this industry to achieve an optimal and economic process. In the present research work, it is attempted to study and provide models for predicting the m...
Accurate prediction of pore water pressure in the body of earth dams during construction with accurate methods is one of the most important components in managing the stability of earth dams. The main objective of this research is to develop hybrid models based on fuzzy neural inference systems and meta-heuristic optimization algorithms. In this regard, the fuzzy neural inference system and opt...
En este art́ıculo, se examina la modelación de series temporales no lineales usando ANFIS. Se discute en primer lugar, su relación con otros modelos estad́ısticos, y se presenta su formulación con una generalización de estos; posteriormente, se analiza una aproximación metodológica para su especificación inicial basada en criterios estad́ısticos; y finalmente se presenta el caso del pronóstico del...
Resumen. En este artículo se presenta una metodología hibrida basada en un modelo difuso del tipo 1 en versión singleton usando un diseño factorial 2 que optimiza el modelo del sistema experto y sirve para realizar inspección en línea. El método de diseño factorial proporciona la base de datos necesaria para realizar la creación de la base de reglas para el modelo difuso y también genera la bas...
To deal with the large number of malicious mobile applications (e.g. mobile malware), a number of malware detection systems have been proposed in the literature. In this paper, we propose a hybrid method to find the optimum parameters that can be used to facilitate mobile malware identification. We also present a multi agent system architecture comprising three system agents (i.e. sniffer, extr...
This paper presents a PID tuning method for unstable processes using an adaptive-network-based-fuzzy-inference system (ANFIS) for given gain and phase margin (GPM) speci)cations. PID tuning methods are widely used to control stable processes. However, PID controller for unstable processes is less common. In this paper, the PID controller parameters can be determined by the ANFIS. Because the de...
Piles have paramount importance for various structural systems in a wide scope of civil and geotechnical engineering works. Accurately predicting the pullout resistance piles is critical long-term resilience infrastructures. In this research, three sophisticated models are employed precisely (Pul) helical piles. Metaheuristic schemes gray wolf optimization (GWO), differential evolution (DE), an...
This paper presents novel GA-ANFIS expert system prototype for dermatological disease detection by using dermatological features and diagnoses collected in real conditions. Nine dermatological features are used as inputs to classifiers that are based on Adaptive Neuro-Fuzzy Inference Systems (ANFIS) for the first level of fuzzy model optimization. After that, they are used as inputs in Genetic ...
