Copied to clipboard
| Challenge: | Existing approaches to generate reviews using attribute identifiers are limited and dependent on how well they can capture vector representations of attributes. |
| Approach: | They propose to leverage attributes as inputs for review generation by using reference sets . they propose to use these references to enrich inductive biases of given attributes . |
| Outcome: | The proposed model improves over previous approaches on automatic and human evaluation metrics. |

| Challenge: | Existing models do not deal with cold-start problem typical in review websites. |
| Approach: | They propose a Hybrid Contextualized Sentiment Classifier that uses word encoder and Cold-Start Aware Attention to pool word vectors. |
| Outcome: | The proposed model performs significantly better on famous datasets despite having less complexity and can be trained much faster. |
