WebMar 18, 2024 · Hopfield Network (HN): In a Hopfield neural network, every neuron is connected with other neurons directly. In this network, a neuron is either ON or OFF. The state of the neurons can change by receiving inputs from other neurons. We generally use Hopfield networks (HNs) to store patterns and memories.
