| Challenge: | Empathy from perspectives is a prediction tool that uses a rater’s perspective to predict the rater's empathy towards a story. |
| Approach: | They developed a model that uses a rater’s perspective as context for predicting the rater's empathy towards a story. |
| Outcome: | The proposed model improves on the EmpathyFromPerspectives dataset and compares it with baseline models. |

| Challenge: | Autoregressive neural machine translation (NMT) uses a tractable likelihood computation and efficient sampling. |
| Approach: | They propose to use an energy-based model to mimic the behavior of the task measure and use it to train an energy based re-ranking algorithm. |
| Outcome: | The proposed model improves on the samples drawn from the NMT with a higher BLEU score than the experimental model and the energy-based re-ranking algorithm. |
