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...
On the simulation of image-based cellular materials in a meshless style[Formula presented] 2021, Computers and Mathematics with Applications Citation Excerpt : Also, high-performance solvers may be required to overcome the possible linear dependency of the standard hat and special functions. Among the...
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 (...
Simulation results show that the chosen optimal kernel width by our proposed MPE formula is very close to the actual one by the conventional method. Moreover, our proposed MPE formula outperforms other selection methods used for fault-free neural networks....

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...
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...
