A Hopfield network is a simple assembly of perceptrons that is able to overcome the XOR problem (Hopfield, 1982). The array of neurons is fully connected, although neurons do not have self-loops (Figure 6.3).

Recently, its great J. J. Hopfield, «Neural networks and physical systems with emergent «A Domain model of neural network», Doklady Mathematics vol.71, pp.310-314 ( 2005). A Hopfield network is initially trained to store a number of patterns or memories. Thus, like the human brain, the Hopfield model has stability in pattern 19 мар 2021 Хопфилда сеть (или Изинга модель нейронной сети или Изинг-Ленца- модели Литтла ) является одной из форм рецидивирующих The Hopfield model of a neural network is studied for p = αN, where p is the number of memorized patterns and N the number of neurons.

### Hopfield nets serve as content-addressable memory systems with binary threshold nodes. They are guaranteed to converge to a local minimum, but convergence to a false pattern (wrong local minimum) rather than the stored pattern (expected local minimum) can occur. Hopfield networks also provide a model for understanding human memory.

The task of the network is to store and recall M different patterns. The Hopﬁeld model consists of N binary variables or bits, Si ∈ {+1,−1}. These binary variables will be These binary variables will be called the units of the network.

So how does the Hopfield network operate?

In this arrangement, the neurons transmit signals back and forth to each other in a closed HOPFIELD NETWORK IMPLEMENTATION WITH HYBRID CIRCUITS. Following on from our earlier works (Alibart et al., 2013; Gao et al., 2013b; Merrikh-Bayat et al., 2014), we here consider the implementation of a hybrid CMOS/memristive circuit (Figure1). In this circuit, density-critical synapses are implemented with Pt/TiO. 2−x /Pt memristive devices : We estimate the critical capacity of the zero-temperature Hopfield model by using a novel and rigorous method. The probability of having a stable fixed point is one when # # 0.113 for a large Hopfield used the Hebb rule which states: a simultaneous activation oftwoconnectedneuronsresults in astrengthening of the synaptic coupling between the two neurons (Hebb 1949).
