径向基函数网络, RBF network 回忆一下SVM里面的高斯核 radial:描述x与中心点的距离 basis function:用来组合的基本函数 RBFN也是一种NN. RBF网络是对一组RBF的线性组合 RBF也是一种描述相似性的方式,RBFN通过 点与中心的距离(相似性)来做特征转换。 full RBFN是指每个样本点都是center,都有权发表对新进x的意见。
3. Commonly Used Radial Basis Functions Gaussian Function φ(r)=exp(−r22σ2) Inverse Multi-Quadric Function φ(r)=(r2+σ2)−0.5 But the network perform poorly for the noisy data for the perfect tracking and large date sets the network will be very cost. To summarize, For a...
