  small data,

  1st and 2nd translator uses the different training data, counting 22000 and 22017 seperately
 +
  2nd translator uses '''random initialized embedding'''
 +
*results (BLEU):
 +
  BASELINE: 36.67 (36.67 is the model at 4750 updates, but we use model at 3000 updates to
 +
                    prevent the case of overfitting, to generate the 2nd translator's training data, for
 +
                    which the BLEU is 34.96)
 +
  best result of our model: 29.81
 +
  This may suggest that that using either the same training data with 1st translator or different
 +
                    one won't influence 2nd translator's performance, instead, using the same one may
 +
                    be better, at least from results. But I have to give a consideration of a smaller size
 +
                    of training data compared to yesterday's model.

*results (BLEU):

  BASELINE: 43.87

  best result of our model: 43.48
 +
  Experiments show that this kind of series or cascade model will definitely impair the final perfor-
 +
                      mance due to information loss as the information flows through the network from
 +
                      end to end. Decoder's smaller vocabulary size compared to encoder's demonstrate
 +
                      this (9000+ -> 6000+).
 +
  The intention of this experiment is looking for a map to solve meaning shift using 2nd translator,
 +
                      but result of whether the map is learned or not is obscured by the smaller vocab size
 +
                      phenomenon.

 +
  emb_size = 310

  learning_rate = 0.001

  small data,
 +
  double-decoder model with joint loss which means the final loss  = 1st decoder's loss + 2nd
 +
  decoder's loss
 +
*results (BLEU):
 +
  BASELINE: 43.87
 +
  best result of our model: '''39.04'''
 +
  The 1st decoder's output is generally better than 2nd decoder's output. The reason may be that
 +
  the second decoder only learns from the first decoder's hidden states because their states are
 +
  almost the same.
 +
*DISCOVERY:
 +
  The reason why double-decoder without joint loss generalizes very bad is that the gap between
 +
  force teaching mechanism (training process) and beam search mechanism (decoding process)
 +
  propagates and expands the error to the output end, which destroys the model when decoding.
 +
*next:
 +
  Try to train double-decoder model without joint loss but with beam search on 1st decoder.

 2nd translator uses random initialized embedding
  • results (BLEU):

2017/05/10 Aodong Li 13:30 22:00 8
  • experiment setting: 
 small data, 
 1st and 2nd translator uses the different training data, counting 22000 and 22017 seperately
 2nd translator uses random initialized embedding
  • results (BLEU): 
 BASELINE: 36.67 (36.67 is the model at 4750 updates, but we use model at 3000 updates to
                    prevent the case of overfitting, to generate the 2nd translator's training data, for 
                    which the BLEU is 34.96)
 best result of our model: 29.81
 This may suggest that that using either the same training data with 1st translator or different
                   one won't influence 2nd translator's performance, instead, using the same one may
                    be better, at least from results. But I have to give a consideration of a smaller size 
                    of training data compared to yesterday's model.

  • experiment setting: 
 small data, 
 1st and 2nd translator uses the same training data, 
 2nd translator uses constant untrainable embedding imported from 1st translator's decoder
  • results (BLEU): 
 BASELINE: 43.87
 best result of our model: 43.48
 Experiments show that this kind of series or cascade model will definitely impair the final perfor-
                     mance due to information loss as the information flows through the network from 
                     end to end. Decoder's smaller vocabulary size compared to encoder's demonstrate
                     this (9000+ -> 6000+).
 The intention of this experiment is looking for a map to solve meaning shift using 2nd translator,
                     but result of whether the map is learned or not is obscured by the smaller vocab size 
                     phenomenon.

 2nd translator uses as training data the concat(Chinese, machine translated English),

  • results (BLEU): 
 BASELINE: 43.87
 best result of our model: 42.19
 Overfitting? In overall, the 2nd translator performs worse than baseline
  • details about experiment 2: 
 hidden_size = 500
 emb_size = 310
 learning_rate = 0.001
 small data, 
 double-decoder model with joint loss which means the final loss  = 1st decoder's loss + 2nd 
 decoder's loss
  • results (BLEU): 
 BASELINE: 43.87
 best result of our model: 39.04
 The 1st decoder's output is generally better than 2nd decoder's output. The reason may be that 
 the second decoder only learns from the first decoder's hidden states because their states are 
 almost the same.
  • DISCOVERY: 
 The reason why double-decoder without joint loss generalizes very bad is that the gap between
 force teaching mechanism (training process) and beam search mechanism (decoding process)
 propagates and expands the error to the output end, which destroys the model when decoding.
  • next: 
 Try to train double-decoder model without joint loss but with beam search on 1st decoder.

checkpoint-100000 translation model BLEU： 11.11

  • source:在秦者名错，与张仪争论,於是惠王使错将伐蜀，遂拔，因而守之。
  • target:在秦国的名叫司马错，曾与张仪发生争论，秦惠王采纳了他的意见，于是司马错率军攻蜀国，攻取后，又让他做了蜀地郡守。
  • trans：当时秦国的人都很欣赏他的建议，与张仪一起商议，所以吴王派使者率军攻打蜀地，一举攻，接着又下令守城 。
  • source:神大用则竭，形大劳则敝，形神离则死 。
  • target:精神过度使用就会衰竭，形体过度劳累就会疲惫，神形分离就会死亡。
  • trans: 精神过度就可衰竭,身体过度劳累就会疲惫，地形也就会死。
  • source:今天子接千岁之统，封泰山，而余不得从行，是命也夫，命也夫！
  • target:现天子继承汉朝千年一统的大业，在泰山举行封禅典礼而我不能随行，这是命啊，是命啊！
  • trans: 现在天子可以继承帝位的成就爵位，爵位至泰山，而我却未能执行先帝的命运。
  • 1.data used Zizhitongjian only(6,000 pairs), we can get BLEU 6 at most.
  • 2.data used Zizhitongjian only(12,000 pairs), we can get BLEU 7 at most.
  • 3.data used Shiji and Zizhitongjian(43,0000 pairs), we can get BLEU about 9.
  • 4.data used Shiji and Zizhitongjian(43,0000 pairs), and split the ancient language text one character by one, we can get BLEU 11.11 at most.
