encoder-decoder
输入序列文本=['1 2 3 4 5' , '6 7 8 9 10' , '11 12 13 14 15' , '16 17 18 19 20' , '21 22 23 24 25']
目标序列文本 = ['one two three four five' , 'six seven eight nine ten' , 'eleven twelve thirteen fourteen fifteen' , 'sixteen seventeen eighteen nineteen twenty' , 'twenty_one twenty_two twenty_three twenty_four twenty_five']
一些参数如下：(‘Vocab size:’, 51, ‘unique words’) (‘Input max length:’, 5, ‘words’) (‘Target max length:’, 5, ‘words’)
(‘Dimension of hidden vectors:’, 20) (‘Number of training stories:’, 5) (‘Number of test stories:’, 5)
tokenize（）\W+ 匹配数字和字母下划线的多个字符 ['Bob', 'dropped', 'the', 'apple', '.', 'Where', 'is', 'the', 'apple', '?']

SA-LSTMs
When LSTMs are initialized with a sequence autoencoder, the methods are called SA-LSTMs
LM-LSTMs
When LSTMs are initialized with a language model, the method is called LM-LSTMs.
