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).

Noisy examples are taught and we test if the network grasps the underlying concepts. Several parameters are modified along the simulation: the number of concepts and examples and the initial noise in the examples. It is obtained the first order transition from the retrieval 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).

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).
