| Challenge: | Existing studies on adapting large language models to perform a variety of tasks in high-stakes domains such as healthcare lack understanding of the extent and contributing factors that allow them to recall relevant knowledge and combine it with presented information. |
| Approach: | They propose to use multiple choice and abstractive question answering to investigate the extent and contributing factors that allow LLMs to recall relevant knowledge and combine it with presented information in the clinical and biomedical domain. |
| Outcome: | The proposed models perform better on 22 datasets in three generalist and three specialist biomedical sub-domains, and show that they can generalise to unseen sub- domains. |

Abhinav Ramesh Kashyap, Thanh-Tung Nguyen, Viktor Schlegel, Stefan Winkler, See-Kiong Ng, Soujanya Poria
| Challenge: | Sentence representations are a critical component in NLP applications such as retrieval, question answering, and text classification. |
| Approach: | They present a systematic review of the literature on sentence representations focusing mostly on deep learning models. |
| Outcome: | The proposed methods highlight the key contributions and challenges in this area and suggest potential avenues for improving the quality and efficiency of sentence representations. |
So Different Yet So Alike! Constrained Unsupervised Text Style Transfer (2022.acl-long)
Copied to clipboard
| Challenge: | Automated transfer of text between domains does not maintain other attributes between the source and translated text. |
| Approach: | They propose a method for automatic transfer of text between domains that preserves semantic content but changes other attributes. |
| Outcome: | The proposed method retains lexical, syntactic and domain-specific constraints between domains for multiple benchmark datasets, including ones where more than one attribute change. |
A Two-Stage Decoder for Efficient ICD Coding (2023.findings-acl)
Copied to clipboard
| Challenge: | Recent automated ICD coding efforts improve performance by encoding medical notes and codes with additional data and knowledge bases. |
| Approach: | They propose a two-stage decoding mechanism to predict ICD codes using hierarchical properties of the codes to split the prediction into two steps: at first, predict the parent code and then predict the child code based on the previous prediction. |
| Outcome: | Experiments on the public MIMIC-III data show that the proposed model performs well in single-model settings without external data or knowledge. |
UDAPTER - Efficient Domain Adaptation Using Adapters (2023.eacl-main)
Copied to clipboard
| Challenge: | Using adapters, unsupervised domain adaptation (UDA) is more parameter efficient and requires large-scale data to be effective. |
| Approach: | They propose to add small bottleneck layers to each layer of a pre-trained language model to make it more parameter efficient by adding adapters. |
| Outcome: | The proposed methods outperform unsupervised domain adaptation methods such as DANN and DSN in natural language inference and sentiment classification tasks. |
Domain Divergences: A Survey and Empirical Analysis (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing literature on divergence measures is lacking in predicting performance of models in new domains. |
| Approach: | They propose a taxonomy of divergence measures consisting of three classes — Information-theoretic, Geometric, and Higher-order measures and identify the relationships between them. |
| Outcome: | The proposed measures are based on three novel use-cases and identify that they are prevalent in three domains and higher-order measures are more common in two. |
