در پژوهش حاضر یک سیستم استنتاج فازی عصبی انطباقپذیر (ANFIS) مبتنی بر تحلیل مولفههای اصلی (PCA) جهت پیشبینی درماندگی مالی شرکتها پیشنهاد شدهاست. این سیستم نه تنها توانایی سازگاری و یادگیری را دارد، بلکه خطا را نیز کاهش میدهد؛ زیرا از پارامترهای اضافی هنگامی که متغیرهای ورودی بیش از حد هستند، اجتناب میکند. برای تأیید اثربخشی این مدل، تعداد 181 شرکت پذیرفته شده در بورس اوراق بهادار تهران (9...
Nonlinear Adaptive Noise Cancellation for 2-D Signals with Adaptive Neuro-Fuzzy Inference Systems Hao Qin Advisor: University of Guelph, 2004 Professor Simon X. Yang Neuro-fuzzy systems are capable of inducing rules from observations, where the adaptive neuro-fuzzy inference system (ANFIS) is an effective method that can be applied to a variety of domains such as pattern recognition, robotics, ...
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...
This article proposes an adaptive neuro-fuzzy inference system (ANFIS) for solving navigation problems of an autonomous ground vehicle (AGV). The system consists of four ANFIS controllers; two of which are used for regulating both the left and right angular velocities of the AGV in order to reach the target position; and other two ANFIS controllers are used for optimal heading adjustment in ord...
In India, the first confirmed case of novel corona virus (COVID-19) was discovered on January 30, 2020. The number cases is increasing day by day, and it crossed 21,53,010 August 9, this paper, a hybrid forecasting model has been proposed to determine for upcoming 10 days based earlier found in India. adaptive neuro-fuzzy inference system (ANFIS) mutation-based Bees Algorithm (mBA). meta-heuris...
در پروژه حاضر، مساله کنترل پیش بین بر مبنای مدل های چندگانه با ترکیب و کلیدزنی بر روی سیستم برج تقطیر مدنظر است. کلیدزنی به این مفهوم است که در هر لحظه از زمان، فرآیند توسط یک مدل خطی توصیف می شود. هدف در اینجا انتخاب کنترلگری است که مناسب ترین رفتار را با توجه به رفتار سیستم در آن لحظه داشته باشد. همچنین در این پایان نامه از سنسورهای نرم جهت تخمین غلطت با استفاده از اطلاعات دما استفاده شده است...
The objective of this study is to investigate a potential application of the Adaptive Neuro-Fuzzy Inference System (ANFIS) and the Geographic Information System (GIS) as a relatively new approach for landslide susceptibility mapping in the Hoa Binh province of Vietnam. Firstly, a landslide inventory map with a total of 118 landslide locations was constructed from various sources. Then the lands...
This paper presents a comparative analysis for stabilization and control of highly non-linear, complex and multi-variable Double Inverted Pendulum on cart. A Matlab-Simulink model of DIP has been built using governing mathematical equations. The objective is to control both the pendulums at vertical position while cart is free to move in horizontal direction. The control of DIP was achieved usi...
This study examines the forecasting performance of Adaptive Neuro Fuzzy Inference System(ANFIS) compared in comparison to statistical autoregressive integrated moving average (ARIMA) and the artificial neural network (ANN) model in forecasting of rice yield production.. To assess the effectiveness of these models, we used 9 years of time series records for rice yield data in Malaysia from 1995 ...
In this study, the efficiency of neuro-fuzzy inference system (ANFIS) and genetic expression programming (GEP) in predicting the transfer length of prestressing strands in prestressed concrete beams was investigated. Many models suggested for the transfer length of prestressing strands usually consider one or two parameters and do not provide consistent accurate prediction. The alternative appr...
