Hidden Layer Neurons
Hidden layer neurons are large groups of neurons between an input layer and output layer– your sensory receptors and your motor actions. Their size, type, and network topology (who connects to who) affect the complexity of problems they solve and decisions they make. Successful networks find solutions because they are statistically favored. Neurons compete for [...]

The program works well for small arrays, but really starts bogging down at sizes 500×500 and above. Anyone doing serious work will want to check [...]
