The effect of pruning neural network structures in remote sensing is investigated. Standard pruning methods, i.e., Optimal Brain Damage and Optimal Brain Surgeon, are compared with pruning based on a genetic algorithm. Direct coding is used to represent the links of the network for optimization with a canonical genetic algorithm using binary representation. The results show that the genetic algorithm
is the only method able to discover a significantly better neural network structure. The main drawback of the genetic approach is the extensive training time required.
