一种CMAC神经网络的直接地址映射

A direct address mapping of the CMAC

在研究CMAC网络模型结构和工作原理的基础上,改进了CMAC权值存贮空间地址映射,提出了新的地址映射公式,应用此公式由输入空间直接映射到一个远小于理论值的紧凑地址空间.并仿真对比了已有的一种机械手逆运动学控制系统,仿真实验表明,应用此映射在更少的存贮空间条件下能达到同样的控制性能,便于硬件的实现.

This paper analyses the structure and the principle of the CMAC model, modifies the address mapping and puts forward the new formula. This formula directly establishes a mapping from the input space to the compact physical address space, of which the capacity is much less than the theoretic value. In contrast to the original scheme of manipulator inverse kinematics control system, the simulations show that there is the same control performances in using less physical space with the application of the new mapping, and it is favor of hardware complement.
