Artificial Neural Networks (feed-forward)

We have got an informal introduction to ANNs as multilayer perceptron models. What does this actually mean? We developed a perceptron algorithm in Chapter 8, Stacked Generalization. According to its definition, the perceptron is a mathematical model of a biological neuron. In actual neurons, the dendrite receives electrical signals from the axons of other neurons, but in a perceptron, these electrical signals are represented as numerical values. At the synapses between the dendrite and axons, electrical signals are modulated in various amounts. This is also modeled in the perceptron by multiplying each input value by a value called weight. An actual neuron fires an output signal only when the total ...
