RETRACTED ARTICLE: Support vector regression methodology for prediction of input displacement of adaptive compliant robotic gripper

Abstract

The prerequisite for new versatile grippers is the capability to locate and perceive protests in their surroundings. It is realized that automated controllers are profoundly nonlinear frameworks, and a faultless numerical model is hard to get, in this way making it troublesome to control utilizing tried and true procedure. Here, a design of an adaptive compliant gripper is presented. This design of the gripper has embedded sensors as part of its structure. The use of embedded sensors in a robot gripper gives the control system the ability to control input displacement of the gripper and to recognize specific shapes of the grasping objects. Since the conventional control strategy is a very challenging task, soft computing based controllers are considered as potential candidates for such an application. In this study, the polynomial and radial basis function (RBF) are applied as the kernel function of Support Vector Regression (SVR) to estimate and predict optimal inputs displacement of the gripper according to experimental tests and shapes of grasping objects. Instead of minimizing the observed training error, SVR poly and SVR rbf attempt to minimize the generalization error bound so as to achieve generalized performance. The experimental results show that an improvement in predictive accuracy and capability of generalization can be achieved by the SVR approach compared to other soft computing methodology.

Kernel Ridge Regression Model Based on Beta-Noise and Its Application in Short-Term Wind Speed Forecasting

“…The short-term wind speed sequence forecast results at point x i+11 each interval of 10 min given by GN-KRR [7,8,32], ν-SVR [33,34], and BN-KRR are illuminated with MAE, MAPE, RMSE, and SEP indicators are used to evaluate the prediction results of the three models at point x i+11 each interval of 10 min shown in Table 1.

Temperature dependent modelling of magnetorheological (MR) dampers using support vector regression

“…This successful forecasting technique, popular due to its superior generalization performance and fast convergence, is extended to identification and modelling of nonlinear systems using the support vector regression (SVR) [27]. With the appropriate kernel functions, SVR has been widely used as an artificial intelligent technique in many areas such as health monitoring [28], concrete strength prediction [29], robotics [30]. Taghavifar and Aref Mardani [31] applied SVR to model energy dissipation of runoff-road vehicles and found that they outperformed the popular ANN technique.…”
