A Multi-Task Approach for Disentangling Syntax and Semantics in Sentence Representations (N19-1)
Copied to clipboard
| Challenge: | Empirically, the model with the best performing syntactic and semantic representations gives rise to the most disentangled representations. |
| Approach: | They propose a generative model that uses latent variables to learn a sentence that uses both latent and latent representations. |
| Outcome: | The proposed model achieves better disentanglement between semantic and syntactic representations by training with multiple losses, including losses that exploit aligned paraphrastic sentences and word-order information. |
Controllable Paraphrase Generation with a Syntactic Exemplar (P19-1)
Copied to clipboard
| Challenge: | Prior work on controllable text generation assumes that the generated attribute can take on a finite set of values known a priori. |
| Approach: | They propose a task where the syntax of a generated sentence is controlled rather by a sentential exemplar. |
| Outcome: | The proposed model achieves improvements over baselines and learns to capture desirable characteristics. |
Variational Sequential Labelers for Semi-Supervised Learning (D18-1)
Copied to clipboard
| Challenge: | a family of multitask variational methods for semi-supervised sequence labeling is currently unclear how to use them in the context of sequence labelling. |
| Approach: | They propose a family of multitask variational methods for semi-supervised sequence labeling using latent variables and a discriminative labeler. |
| Outcome: | The proposed models outperform standard sequential baselines on 8 sequence labeling datasets and improve further with unlabeled data. |
