Distributional Discrepancy: A Metric for Unconditional Text Generation
Table 6: Ten generators are ranked according to FED score. The lower the score is, the better is the performance.
['GPT-21.0', 'GPT-20.8', 'GPT-20.6', 'GPT-20.4', 'LSTM1.0', 'LSTM0.8', 'LSTM0.6', 'LSTM0.4', 'GPT-20.2', 'LSTM0.2']
Considering that the rank of the FED scores is similar to that of our own, we inspected its performance in detail. The discrimination is significantly small, and there is only a 0.006 difference between the best and worst scores. For the worst scores, several generators are assigned the same scores; however, their performances are different from each other.
