摘　　要： 联结主义是20世纪80年代早期所复兴的认知心理学的另一研究范式。它是一种计算的研究取向,认为认知其实就是相互联系的具有活性值的神经单元所构成的网络的动态整体活动,存在于神经网络联结中或权重里的知识信息,是整个交互作用的神经节的激活模式,通过调整权重就可以改变网络的联结关系并进而改变网络的功能;联结主义的基本网络模型是由输入层、隐含层和输出层三个神经单元层组成的,单元层被定义为拓扑的或关于网络的联结的类型,因此构造神经网络的结构,实质上就是构造神经网络的拓扑结构。 connectionism, retrieving in the early 80s of the 20th centenary, is another paradigm of cognitive psychology. It is a computing research approach, it believes that cognition is the action of the network which is consisted of the interconnected neural units of having activation values, it thinks that information and knowledge which lies in the connection or the weight of neural network is the activation pattern of the interacted neural nodes, by adjusting the weights , the connected relation and function of the network can be altered;the basic connectionist model comprises three neural unit layers such as input layer ,hidden layer and output layer, the unit layer is defined as the topology or the connected type of network, thus constructing the structure of neural network is constructing the topology of neural network.
