Python mse Examples

Example #1

File: de.py Project: azmihafizha/evolving_ann

def fitness(kr):
    return 1 / (jst.mse(inps, kr, num_input, num_hidden, num_output) + 0.0001)

Example #2

File: de.py Project: azmihafizha/evolving_ann

def fitness(kr):
	return 1/(jst.mse(inps,kr,num_hidden)+0.1)

Example #3
