    match = re.search(r"[\.\?\!][^\.\?\!]*$", complete_answer)

Training Details

• We train our model with PEFT. PEFT is a technique that does not tune all parameters of a model during fine-tuning, but only a small subset of parameters. By tuning only a few parameters while leaving others fixed, the model is less likely to suffer from catastrophic forgetting, where the model forgets previously learned tasks when it learns new ones. This significantly reduces computation and storage costs.

• We use QLora to train the base model. Quantized Low Rank Adapters (QLoRA) is an efficient technique that uses 4-bit quantized pre-trained language models to fine-tune 65 billion parameter models on a 48 GB GPU while significantly reducing memory usage. The method uses NormalFloat 4-bit (NF4), a new data type that is theoretically optimal for normally distributed weights; Double Quantization, which further quantizes quantization constants to reduce average memory usage; and Paged Optimizers, which manage memory spikes during mini-batch processing, to increase memory efficiency without sacrificing performance.

• Also, we performed instruction tuning using the data that we collected and the kyujinpy/KOR-OpenOrca-Platypus-v3 dataset on the hugging face. Instruction tuning is learning in a supervised learning format that uses instructions and input data together as input and output data as a pair. In other words, instruction tuning involves fine-tuning a pre-trained model for a specific task or set of tasks, where the model is taught to follow specific instructions or guidelines. Instruction tuning is a type of Supervised Fine-tuning (SFT) that aims to improve the generality and adaptability of a model by introducing an additional dimension that enables the model to understand and follow specific instructions.

중앙은행의 역할에 대해서 설명해줄래?

중앙은행은 국가가 발행하는 화폐의 유통과 경제의 안정적 운영을 위해 설립된 국가기관입니다. 중앙은행은 ① 경제의 안정적 운영을 위해 금융기관을 감독하고, 화폐의 발행과 통화정책을 실시하는 기능을 합니다. ② 통화정책의 실행에는 중앙은행이 유동성(Liquidity)을 공급하고, 이자율을 조정하여 수요와 공급을 조절하는 일, 예금준비금을 유지하는 일, 환율조절 등이 포함됩니다. ③ 중앙은행은 금융기관의 대출한도 초과대출, 외환거래, 지폐의 발행과 교환을 관리하는 업무도 담당합니다. ④ 통화정책의 실시는 화폐와 신용의 발행 및 공급을 통제를 통해 물가안정과 고용을 증대하고 경제의 균형성장을 도모하는 것을 목표로 하고 있습니다.
