Artificial Neuron Output=f(Σ(Weights*Inputs)) Basic Structure
3
Several Layered Network A Typical Network Organizes these Neurons into layers that feed into each other sequentially
4
Typical Transfer Functions

Implementation void distributeweightpoints(Connections con){ vector list = con.weights; int totalpoints=con.points; double total=weightsummation(list); double temp; for(unsigned int i=0; i<con.weights.size(); i++){ temp=list[i].value/total; if(temp<1/totalpoints){ con.weights[i]=0;} else{ con.weights[i]=temp;} }
