Networks: A network is a system of interconnected components that communicate with and influence each other. Networks can be found in both natural and artificial systems. E.g., the nervous system, or the internet. See also Neural networks, Artificial neural networks, Connectionism.

Yuichi Shoda on Networks - Dictionary of Arguments

Corr I 481
Networks/Shoda/Smith: One notable property of dynamic networks is the emergence of distinctive sets of activation patterns into which the network settles over time (Hopfield 1982)(1). Called attractor states, these stable patterns are analogous to the shapes that straw hats can snap into. These shapes represent ‘stable’ states because the hat takes on, and remains in, one of these shapes when it is let go after being distorted. Because component parts of the straw hat mutually support each other, the hat tends to remain in that shape (Shoda and Smith 2004)(2).
As originally proposed by Hebb (1949)(3), a basic neural network mechanism of learning is that the simultaneous activation of two units in a network strengthens the association between them. This principle has been used in a variety of neural network models, playing an important role in cognitive neuroscience (e.g., Rumelhart and McClelland 1986)(4).
Applied to the CAPS system (Cognitive-Affective Processing System, >Control processes/Shoda/Smith), it suggests that CAPS elements that become activated simultaneously may begin to form stronger associations with one other, eventually becoming a nodal cluster of mutually activating thoughts. Once any component of this cluster of thoughts becomes activated, it may in turn activate others in such a way that it becomes very difficult to break out of the cycle of mutual activation among the component cognitions that makeup the attractor state. In this manner, chronic accessibility of the network connections may increase over time.
