I am currently working on a refined version of NeuralNetwork (HAMA-770),
the new MLP will be implemented based on it. To quickly fix this problem
you mentioned, I will simply increase the training time to reduce the
chance of training failed.

Oh, this is caused by the testing of the MultilayerPerceptron, with small
probability, the model will fail to learn the correct answer, I will fix
this problem.
