[Jargon File] Hebbian learning intelligence> The most common way to train a neural network; a kind of unsupervised learning; named after canadian neuropsychologist, Donald O. Hebb. The algorithm is based on Hebbs Postulate, which states that where one cells firing repeatedly contributes to the firing of another cell, the magnitude of this contribution will tend to increase gradually with time. 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. http://neuron-ai. tuke. sk/NCS/VOL1/P3_html/node14. html.
