Although the RBF is the most widely used SVR kernel function,the expression complexity of RBF makes it difficult to get analytical formula of rolling optimization in model predictive control.A model of predictive control based on RBF-SVR is established,the multi-agent particle swarm optimization (...

Among the...
Curve fittingNeural networksStopping powerThis article presents a new framework for fitting measured scientific data to a simple empirical formula by introducing an additional linear neuron to the standard Gaussian kernel radial basis function (RBF) neural networks. The proposed method is first used to...

After that, the L2-soft-margin parameter C is obtained by an analytic formula in terms of a jackknife estimate of the perturbation in the eigenvalues of the kernel matrix. In comparison with SVM model selection based on differentiable bounds, such as radius/margin bounds, experimental results on...

The inverse model formula shared by both neural controllers is given below: 𝐹(𝑘)=RBF(𝑣(𝑘),𝜃(𝑘),𝜃˙(𝑘),𝜃(𝑘+1))F(k)=RBF(v(k),θ(k),θ˙(k),θ(k+1)) (26) Table 4. Notation and parameter values for the inverted pendulum. The state Equations (25...
Therefore, through the above formula, we can deduce that the output expression is 𝑯𝑖=(∑∀𝑗𝑒𝜃(𝑭𝑖)𝑇𝜑(𝑭𝑗)×𝑾𝑔𝑭𝑗)/∑∀𝑗𝑓(𝑭𝑖,𝑭𝑗)Hi=(∑∀jeθ(Fi)Tφ(Fj)×WgFj)/∑∀jf(Fi,Fj) (6) Figure 5 shows the architecture of the...
