| Challenge: | a personalized dialogue system can generate user-customized responses based on long-term memory about the user's persona. |
| Approach: | They propose a method for building a personalized open-domain dialogue system . they combine weighted dataset blending and negative persona information augmentation methods . |
| Outcome: | The proposed method balances dialogue fluency and tendency to ground while introducing a response-type label to improve controllability and explainability of the grounded responses. |

| Challenge: | Domain Adaptive Continual Pretraining (DACP) is a method to mitigate performance degradation in small LLMs and enhance their effectiveness in target domains. |
| Approach: | They propose a continual pretraining methodology that optimizes sLLMs within service domains and enhances their effectiveness in target domains. |
| Outcome: | The proposed model achieves significant gains in target-domain performance while preserving general capabilities, offering a cost-efficient and scalable solution for enterprise-level deployment. |
