Data-Efficient Concept Extraction from Pre-trained Language Models for Commonsense Explanation Generation (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods to extract concepts from pre-trained language models are not suitable for commonsense explanation generation. |
| Approach: | They propose a method to extract the key explanation concept from pre-trained language models by fine-tuning it with 20% training data and using a metric to evaluate the retrieved concepts. |
| Outcome: | The proposed method improves evaluation metrics over pre-trained language models and the existing models. |
Assessing Combinational Generalization of Language Models in Biased Scenarios (2022.aacl-short)
Copied to clipboard
| Challenge: | Existing work focuses on assessing in-domain knowledge, but shedding light on what pre-trained Language Models learn is important. |
| Approach: | They propose a method to assess a PLM's generalization capacity in biased scenarios by combining component combinations where it could be easy for the PLMs to learn shortcuts from the training corpus. |
| Outcome: | The proposed model can overcome distribution shifts in the training corpus and with sufficient data. |
