A common solution is to split the training set further to create a validation set.Test set: A set of examples used only to assess the performance [generalization] of a fully specified classifier." The error surface will be different for different sets of data from your data set (batch learning).By commenting, you are accepting the DISQUS terms of service.def train(self, train, validation, N=0.3, M=0.1): # N: learning rate # M: momentum factor accuracy = list() while(True): error = 0.0 for p in train: input, target = p self.update(input) error = error Propagate(target, N, M) print "validation" total = 0 for p in validation: input, target = p output = self.update(input) total = sum([abs(target - output) for target, output in zip(target, output)]) #calculates sum of absolute diference between target and output accuracy.append(total) print min(accuracy) print sum(accuracy[-5:])/5 #if i % 100 == 0: print 'error %-14f' % error if ?

EDIT: Also, in the case you do not have enough data for a validation set, you can use crossvalidation to tune the parameters as well as estimate the test error.
