> 中文摘要: 本文提出一种具有非线性映射能力的RAM式联想存贮器(RAM—AM),通过将二值输入模式分解成若干个子模式,并作为RAM的寻址地址,来训练该联想存贮器.存贮编码采用相关矩阵方法,此AM作为异联想存贮器能成功地回忆,如XOR、高阶奇偶校验一类高阶非线性问题,说明了映射能力对于模式划分行为的依赖性.最后从理论上证明了所提模型的信噪比大大高于Hopfield模型的信噪比及在大量神经元存在下的可实现性,实验例子证实了这种模型的可行性.
Abstract:In this paper,a RAM associative memory(RAM—AM)with the nonlinear mapping ability is proposed.Every input pattern is divided into a number of sub—patterns which can address RAM to train the RAM—AM,its storage matrix is encoded through correlative matrix method.As a heteroassociative memory,the AM can succeassy recall high—order nonlinear problems such as XOR and the parities problems.The analysis shows that its mapping ability depends on the partition for input patterns.Finally,this paper theoretically proves that the proposed AM has higher signal—to—noise ratio than those of Hopfield—like models and realizability under the existence of a large number of neurons.The experimental results confirm its feasibility.
