Gaussian basis functionRegularizationSmoothing parameter selectionWe consider the problem of constructing functional regression models for scalar responses and functional predictors, using Gaussian basis functions along with the technique of regularization. An advantage of our regularized Gaussian basis expansions ...

regression matrix is employed to select a suitable set of radial basis function centers from a large number of possible candidates and this provides, for the first time, fully automatic selection procedure for identifying parsimonious radial basis function models of structure-unknown non-linear systems...
Compared to statistical regression models, RBFN models demonstrated an improvement of more than 20%. For the etch rate, the improvement was considerably increased to more than 40%. It is therefore expected that RBFN can be effectively used to construct prediction models of plasma processes....

实际上估计参数的时候就是抓住这K+M个function 一般来说,不会使用超过三次样条的多项式了,取M=1,2,4 固定konts的样条被称作regression splines,进行这样的操作需要选择样条的次数、节点的个数、节点的位置。 Natural Cubic Splines 使用多项式拟合数据在边界会出现方差较大的情况,这对于样条更为突出相较于全局的多项...

in which I is the indicator function. It may be difficult to see from the equation above, but this yields a regression matrix which is largely sparse, e.g. the majority of elements will be zero. This may increase the overall numerical complexity of the model, but as the regression matrix...

In this study, fuzzy regression (FR) models with fuzzy inputs and outputs are discussed. Some of the FR methods based on linear programming and fuzzy least squares in the literature are explained. Within this study, we propose a Fuzzy Radial Basis Function (FRBF) Network to obtain the estim...
