1. **[SOLAR 10.7B: Scaling Large Language Models with Simple yet Effective Depth Up-Scaling](https://md.research.elamur.ai/free/en/papers/kim-2023-solar-10-7b-scaling-large/)** *(2023 · 77 citations)* Scaling up LLMs usually means training ever-larger networks or adopting mixture-of-experts designs, which complicate training and inference pipelines.
2. **[sDPO: Don't Use Your Data All at Once](https://md.research.elamur.ai/free/en/papers/kim-2024-sdpo-don-t-use-data/)** *(2024 · 19 citations)* Direct Preference Optimization (DPO) aligns an LLM by comparing its log-probability ratios for chosen and rejected responses against those of a frozen reference model.
3. **[PEEP-Talk: A Situational Dialogue-based Chatbot for English Education](https://md.research.elamur.ai/free/en/papers/lee-2023-peep-talk-situational-dialogue-based/)** *(2023 · 9 citations)* Learners of English as a foreign language rarely get to practise realistic conversation. Existing tutoring chatbots tend to be rule-based, cope poorly with off-topic input, and give little feedback. PEEP-Talk addresses this with three parts:
