HEBBIAN LEARNING IN LARGE RECURRENT NEURAL NETWORKS

Hebbian learning in biological neural networks is when a synapse is strengthened when a signal passes through it and both the pre-synaptic neuron and post-synaptic neuron fire (activate) within a given time interval. A short version is that neurons that fire together, wire together.

These experiments give evidence that a balance of Hebbian learning rules, regulated in a meaningful way, can lead to useful neural networks. First, it is shown that local Hebbian rules alone can, with high probability, guide a suﬃciently large neural net-work to a meaningful state when trained on simple classiﬁcation problems. Second, the networks are modiﬁed to be recurrent, and it is
