7 types of Artificial Neural Networks for Natural Language Processing

It requires stationary inputs and is thus not a general RNN, as it does not process sequences of patterns. It guarantees that it will converge. If the connections are trained using Hebbian learning then the Hopfield network can perform as robust content-addressable memoryresistant to connection alteration.

Bidirectional associative memory[ edit ] Main article: Bidirectional associative memory Introduced by Bart Kosko, [21] a bidirectional associative memory BAM network is a variant of a Hopfield network that stores associative data as a vector.

The bi-directionality comes from passing information through a matrix and its transpose. Typically, bipolar encoding is preferred to binary encoding of the associative pairs. Recently, stochastic BAM models using Markov stepping were optimized for increased network stability and relevance to real-world applications.

Echo state network The echo state network ESN has a sparsely connected random hidden layer. The weights of output neurons are the only part of the network that can change be trained. ESNs are good at reproducing certain time series.

The gradient backpropagation can be regulated to avoid gradient vanishing and exploding in order to keep long or short-term memory. The cross-neuron information is explored in the next layers. Using skip connections, deep networks can be trained.

Recursive neural network A recursive neural network [27] is created by applying the same set of weights recursively over a differentiable graph-like structure by traversing the structure in topological order. Such networks are typically also trained by the reverse mode of automatic differentiation.

A special case of recursive neural networks is the RNN whose structure corresponds to a linear chain.

Recursive neural networks have been applied to natural language processing. Only unpredictable inputs of some RNN in the hierarchy become inputs to the next higher level RNN, which therefore recomputes its internal state only rarely. This is done such that the input sequence can be precisely reconstructed from the representation at the highest level.

The system effectively minimises the description length or the negative logarithm of the probability of the data. This makes it easy for the automatizer to learn appropriate, rarely changing memories across long intervals. In turn this helps the automatizer to make many of its once unpredictable inputs predictable, such that the chunker can focus on the remaining unpredictable events.

A neural network is usually composed of simple decision-making elements that are connected with variable weights and strengths. Each of these elements is called a neurode. The term neurode is similar to the biological neuron; modified slightly to indicate its artificial nature.

Artificial Neural Network Essentials NEURAL NETWORKS by Christos Stergiou and Dimitrios Siganos | Abstract This report is an introduction to Artificial Neural Networks.

Figure 1: A Simple Neural Network Diagram. Basically, all artificial neural networks have a similar structure or topology as shown in Figure1. In that structure some of the neurons interfaces to the real world to receive its inputs.

Other neurons provide the real world with the network's outputs. The term neural network was traditionally used to refer to a network or circuit of biological neurons.[1] The modern usage of the term often refers to artificial neural networks, which are composed of artificial neurons or nodes.

Thus the term has two distinct usages: Biological neural networks are.
