Understanding dynamic neural networks


Dynamic neural networks differ from static networks in that they continue learning after the training phase. They can make adjustments to their structure independently of external modification. A feedforward neural network (FNN) is one of the earliest and simplest dynamic neural networks. This type of network, as its name implies, only feeds information forward and does not form any cycles. This type of network formed the foundation for much of the later work in dynamic ANNs. We will show in-depth examples of two types of dynamic networks in this section, MLP networks and SOMs.

Multilayer perceptron networks

A MLP network is a FNN with multiple layers. The network uses supervised learning with backpropagation where feedback is sent to early layers to assist in the learning process. Some of the neurons use a nonlinear activation function mimicking biological neurons. Every nodes of one layer is fully connected to the following layer.

We will use a dataset...
