Robust Semantic Parsing with Adversarial Learning for Domain Generalization
Table 4: Frame Identification score for LUs with the highest variation in cluster distribution
['LU', '[ITALIC] biGRU D1', '[ITALIC] biGRU D3', '[ITALIC] biGRU+ [ITALIC] AC D1', '[ITALIC] biGRU+ [ITALIC] AC D3']
When we apply biGRU+AC, the gains observed on Frame Identification are not constant across LUs. To analyze the impact of the adversarial approach, we compare for each LU the distribution across clusters of the sentences containing the given LU. This is done separately for D1 and D3 (for D3, sentences are projected into the clusters by choosing the less distant cluster centroid). These are also the LUs that are the most positively affected by the adversarial strategy.
