- hebbian learning — (artificial intelligence) The most common way to train a neural network; a kind of unsupervised learning; named after canadian neuropsychologist, Donald O. Hebb.

This means that what may start as little more than a coincidental relationship between the firing of two nearby neurons becomes strongly causal. Despite limitations with Hebbian learning, e.g., the inability to learn certain patterns, variations such as Signal Hebbian Learning and Differential Hebbian Learning are still used.
