HaRiM+: Evaluating Summary Quality with Hallucination Risk (2022.aacl-main)
Copied to clipboard
| Challenge: | Existing summarization models are limited in measuring the factual inconsistency of generated summaries. |
| Approach: | They propose a decoder overconfidence-regularizing objective as a hallucination risk measurement to better estimate the quality of generated summaries. |
| Outcome: | The proposed metric is reference-free and requires no training or modules . it records state-of-the-art correlation to human judgment on three sets of summary-quality annotations. |

| Challenge: | Existing methods to train text style transfer models with adversarial loss degrade fluency compared to other metrics. |
| Approach: | They propose a method which leverages a pretrained language model to improve fluency by restructuring the discriminator and the model itself. |
| Outcome: | The proposed model achieves state-of-the-art on three public benchmarks and achieved state-outperformance on the overall metrics. |
Align-to-Distill: Trainable Attention Alignment for Knowledge Distillation in Neural Machine Translation (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing knowledge distillation approaches to NMT often rely on heuristics when deciding which teacher layers to distill from. |
| Approach: | They propose an approach to align student attention heads with their teacher counterparts by heuristics to solve a feature mapping problem. |
| Outcome: | The proposed strategy shows gains of +3.61 and +0.63 BLEU points for WMT-2022 DeDsb and WMT-2014 EnDe compared to baselines. |
