Curriculum-based transfer learning for an effective end-to-end spoken language understanding and domain portability
Table 3: Performance of end-to-end SLU system in starred mode with beam-search decoding on the MEDIA test
['Training chain', 'CER', 'CVER']
The ⋆ symbol is used to indicate a neural model emits its outputs though the starred mode. Notice that the best results are reached when the two last training processes in the curriculum chain use this mode. These training processes, SFP+M(⋆) and SFM(⋆) use very close semantic annotations as output. When we also applied the starred mode on the NER training process, we degraded the global results. We think the starred mode must not be applied too early in the training chain, and would be applied on sub-tasks very close to the final target. For fair comparison with a state-of-the-art approach, we present in the next section a pipeline system we develop that takes benefits of the very good quality of our ASR outputs.
