Application of particle swarm optimization with ANFIS model for double scroll chaotic system

Abstract

The predictions for the original chaos patterns can be used to correct the distorted chaos pattern which has changed due to any changes whether from undesired disturbance or additional information which can hide under chaos pattern. This information can be recovered when the original chaos pattern is predicted. But unpredictability is most features of chaos, and time series prediction can be used based on the collection of past observations of a variable and analysis it to obtain the underlying relationships and then extrapolate future time series. The additional information often prunes away by several techniques. This paper shows how the chaotic time series prediction is difficult and distort even if Neuro-Fuzzy such as Adaptive Neural Fuzzy Inference System (ANFIS) is used under any disturbance. The paper combined particle swarm (PSO) and (ANFIS) to exam the prediction model and predict the original chaos patterns which comes from the double scroll circuit. Changes in the bias of the nonlinear resistor were used as a disturbance. The predicted chaotic data is compared with data from the chaotic circuit.

Trajectory Tracking of Soccer Motion Based on Multiobject Detection Algorithm

“…Based on the above tness functions, F A × Y + B × OB(i) can be obtained, where A and B are the weighting factors of the two functions and are any real numbers greater than or equal to zero [14]. e proportion of Y and OB(i) in the tness function can be adjusted by adjusting the size of A and B.…”

A hybrid deep learning optimization for predicting the spread of a new emerging infectious disease

“…Several studies in the field of machine learning have been conducted to predict the COVID-19 spreading cases using a single method such as artificial neural network (ANN) [14], multilayer perception (MLP) [15], random forest [16], and Gaussian Nave Bayes [17]. Unfortunately, the construction of several individual algorithms often results in a decrease in model performance [18] as more and more parameters must Int J Artif Intell ISSN: 2252-8938 …”

Big data clustering based on spark chaotic improved particle swarm optimization

“…Rather than advocating the combination of different algorithms, alternative methods leverage novel ideas derived from contemporary theories, such as chaos theory, to enhance their efficacy in a straightforward manner [38]− [40]. A promising approach to model systems heavily dependent on initial conditions, such as meta-heuristics, is through the use of chaotic maps.…”
