【摘要】 着重讨论了二维自关联和异关联Hopfield模型的内积形式,并提出了两种新的光电实现系统。其中采用了偏振编码加1/2波片的方法来解决两极编码问题;另一特点是只要改变第一块记忆模板以及相应地调整反馈阈值就可以实现异关联。最后给出了计算机模拟及原理性实验结果。更多还原

【Abstract】 The auto-and hetero-association of the Hopfield modeldescribed in the form of inner-product are discussed here, two kinds ofnew optoelectronic implementation systems the two-step multi-imag-ing system and the two-step correlation system, are presented. Thepolarization coding and 1/2 wave plate are employed to solve the prob-lem of bipolar coding. Another advantage of these systems is that het-ero--association can also be realized in the system for auto-association,only if the first memory mask and the feedback threshold values areadjusted accordingly. Finally, computer simulations and experimentalresults are presented.更多还原
