Furthermore , due to the symmetry restriction of traditional radial basis function networks ( rbfn ) with gaussian function , the asymmetric gaussian basis function ( agbf ) is proposed to construct the full adaptive agbfn . because the asymmetry gaussian function ' s variability and malleability are higher than the traditional one , the asymmetry gaussian basis function can provide the agbfn which own a higher flexibility and can approach the true result more easily 针对这一问题,文中提出了一种全自适应的不对称高斯基函数网络( agbfn )结构,网络的基函数采用具有不对称宽度的伪高斯函数,和常规的高斯函数相比,具有更大的可变性和延展性,从而使得隐层神经元在函数近似上具有更高的适应性,提高了神经网络的学习能力。
