Pretrained Semantic Speech Embeddings for End-to-End Spoken Language Understanding via Cross-Modal Teacher-Student Learning
Table 5: Effect of objective function
['Objective', 'Accuracy on Test, %', 'Accuracy on Test, %', 'Accuracy on Test, %', 'Valid value', 'Valid value', 'Valid value']
Overall, these results indicate that the evaluated objective functions behave similarly in this task, however L1 distance based objective function yields slightly better results.
