Techopedia Explains Hebbian Theory

Hebbian theory is named after Donald Hebb, a neuroscientist from Nova Scotia who wrote “The Organization of Behavior” in 1949, which has been part of the basis for the development of artificial neural networks.

In modern artificial neural networks, algorithms can update weights of neural connections. Professionals sometimes talk about “Hebb’s rule” that describes how these connections work and how they change. Part of the appeal of Hebbian theory is the idea that by changing neural weights and associations, engineers can get different results out of sophisticated artificial neural networks.
