A distinguished physicist who is currently professor of chemistry and biology at the California Institute of Technology, Hopfield previously held positions at Bell Laboratories, the University of California at Berkeley, and Princeton.
Hopfield proposed a design for a neural network modeled on a spin glass, a type of physical system in which each atom in a matrix of atoms spins pointing up or down, influencing the spin of its neighbors until the matrix reaches a stable configuration.
In the neural networks, known as Hopfield nets, units influence the activation of their neighbors until a stable configuration is achieved.
