| Challenge: | GPT-3 has been used to train large-scale language models on hundreds of billion scale data. |
| Approach: | They propose a Korean variant of GPT-3 that uses Korean tokens to train in-context models. |
| Outcome: | The proposed method shows state-of-the-art zero-shot and few-shot learning on downstream tasks in Korean. |

| Challenge: | Recent studies on large-scale in-context language models have reported successful in-const zero- and few-shot learning ability. |
| Approach: | They investigate the effects of the pretraining corpus on in-context learning in a Korean-centric model. |
| Outcome: | The study shows that pretraining corpus size does not determine in-context learning ability . the findings suggest that in-constext learning is not always competitive . |
GPT3Mix: Leveraging Large-scale Language Models for Text Augmentation (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Recent studies report that prompt-based direct classification eliminates the need for fine-tuning but lacks data and inference scalability. |
| Approach: | They propose a data augmentation technique that leverages large-scale language models to generate real text samples from a mixture of real samples. |
| Outcome: | The proposed method outperforms existing methods on diverse classification tasks. |

| Challenge: | Existing studies do not deal with cases where memorized information is outdated, which may cause confusion in later conversations. |
| Approach: | They propose a task where bots keep track of and bring up the latest information about users while conversing through multiple sessions. |
| Outcome: | The proposed method outperforms baselines that leave the stored memory unchanged in terms of engagingness and humanness, and a larger performance gap in the later sessions. |
Building a Role Specified Open-Domain Dialogue System Leveraging Large-Scale Language Models (2022.naacl-main)
Copied to clipboard
| Challenge: | Recent large-scale language models have produced human-like responses in open-domain dialogue systems. |
| Approach: | They propose a framework for imposing roles on open-domain dialogue systems . they use few-shot learning to build a Korean dialogue dataset from scratch . |
| Outcome: | The proposed framework meets role specifications while maintaining conversational abilities. |
