Function-Private Identity-Based Encryption: Hiding the Function in Functional Encryption
Function privacy identity-based encryption functional encryption
2015/8/5
In light of such an inherent difficulty, any meaningful notion of function privacy must be based
on the minimal assumption that, from the adversary's point of view, identities that correspond to...

为了解决以往正则最小二乘法求权重向量时遇到的矩阵接近奇异而无法求逆的问题，采用广义逆矩阵的方法求多层径向基函数网络中各层的权重向量，并将这种方法引至多层径向基函数网络的遗传算法中。采用实函数逼近，混沌时间序列建模与预测等仿真实验对算法进行验证。结果表明，采用广义逆矩阵的方法要比正则最小二乘法在逼近精度上高1至2个数量级。
