Mar 24 2011Each layer contains various nodes connected by arcs and weighted by some arithmetic function When the input data exceed some threshold the neural network "fires" The goal in our case was to classify individuals as high- or low-risk for AMD (the output) from genetic and clinical risk factor data (the inputs) weighted directed graph and to refine an initial solution found with the genetic method into a locally optimal solution by applying the Kerhighan-Lin algorithm Approach: • Fitness = expected number of button presses on mission weighted by criticality factor (Random allocation requires about 35 button presses on a mission )
