4.5. Artificial Neural Networks

The objective of a predictive analytics algorithm is to model the relationship between input and output variables. The neural network technique approaches this problem by developing a mathematical explanation that closely resembles the biological process of a neuron. Although the developers of this technique have used many biological terms to explain the inner workings of neural network modeling process, it has a simple mathematical foundation. Consider the simple linear mathematical model:

Y=1+2X1+3X2+4X3

Where Y is the calculated output and X1,X2,andX3 are input attributes. 1 is the intercept and 2, 3, and 4 are the ...
