THUMT: An Open Source Toolkit for Neural Machine Translation
Table 1: Comparison between GroundHog and THUMT.
['Toolkit', 'Criterion', 'Optimizer', 'MT02', 'MT03', 'MT04', 'MT05', 'MT06', 'MT08', 'All']
Experimental results show that the translation performance of THUMT is comparable to Groundhog using MLE. Due to the capability to include evaluation metrics in during, MRT obtain significant improvements over MLE. Another finding is that Adam leads to consistent and significant improvements over AdaDelta.
