Learning of single patterns and a temporal pattern sequence in a network when the coupling coefficients between the network elements change their values according to a definite coupling function is described. In contrast to technical systems (e.g. film, tape) where temporal sequences are often encoded in the storage location, the network stores information only by changing the values of the coupling coefficients. A network of 100 elements was stimulated on an UNIVAC 1100/80 computer. Eight single patterns and a sequence of these patterns were offered at the input of the network. After the learning process the network reproduces every stored pattern as an output signal when only parts of it are fed in. The activity, that is the sum of all output signals, is regulated by an external control signal. By setting that control signal to a suitable value the network is able to reproduce the stored pattern sequence starting from any arbitrary pattern. Lowering the external control signal during that process causes the network to hold the last presented pattern until the external control signal is changed again. It is speculated that the coupling function implemented in the stimulation may be analogous to a characteristic describing the chemical process of cooperative binding.
描述了当网络元件之间的耦合系数根据确定的耦合函数改变其值时，网络中单个模式和时间模式序列的学习情况。与技术系统（如胶片、磁带）不同，在技术系统中时间序列通常编码在存储位置，而该网络仅通过改变耦合系数的值来存储信息。在一台UNIVAC 1100/80计算机上对一个由100个元件组成的网络进行了刺激。在网络的输入端提供了八个单个模式以及这些模式的一个序列。学习过程之后，当仅输入部分存储模式时，网络会将每个存储模式作为输出信号进行再现。活动，即所有输出信号的总和，由外部控制信号调节。通过将该控制信号设置为合适的值，网络能够从任何任意模式开始再现存储的模式序列。在此过程中降低外部控制信号会使网络保持最后呈现的模式，直到外部控制信号再次改变。据推测，刺激中实现的耦合函数可能类似于描述协同结合化学过程的一个特征。
