| Challenge: | Using pretrained transformer models for automatically summarizing doctor-patient conversations presents challenges . limited training data, domain shift, long and noisy transcripts, and high target summary variability are challenges compared to human annotators. |
| Approach: | They propose a method for fine-tuning pretrained transformer models for automatically summarizing doctor-patient conversations directly from transcripts. |
| Outcome: | The proposed method surpasses the performance of an average human annotator and the quality of previous published work for the task. |
An Empirical Investigation of Beam-Aware Training in Supertagging (2020.findings-emnlp)

| Challenge: | Structured prediction is often approached by training a local normalized model with maximum likelihood and decoding approximately with beam search. |
| Approach: | They propose a meta-algorithm that captures beam-aware training algorithms and suggests new ones. |
| Outcome: | The proposed algorithm improves performance for both models and the simpler model . it also improves the model which must manage uncertainty during decoding . |
