示例1: test

# 需要导入模块: from NeuralNetwork import NeuralNetwork [as 别名]
# 或者: from NeuralNetwork.NeuralNetwork import threshold [as 别名]

    print("post reading...")
    pr = PostReader(base_directory, ignore_word_file, filtered)

    print("creating neural network...")
    nn = NeuralNetwork(pr.get_word_set(), nb_hidden_neurons, nb_max_iteration)

    print("training...")
    training_set = pr.get_training_set()
    t0 = time.clock()
    nb_iteration = nn.train(training_set)
    training_time = time.clock() - t0

    print("verification...")
    t0 = time.clock()
    verification_set = pr.get_verification_set()
    verification_time = time.clock() - t0
    nb_correct = 0
