Neuron

Each connection $x_i$ is weighted by $w_i$

The output $y$ is determined by the NN transfer function:


\begin{displaymath}y \;=\; \left[ \begin{array}{ll} 1 & {\rm if} \;\Sigma_{i=1}... ...\; {\rm Threshold} \\ 0 & {\rm otherwise} \end{array} \right.\end{displaymath}

This is a step transfer function
