KoRAE

We introduce KoRAE which finetuned with filtered high-quality Korean dataset.

The KoRAE is output of combination of high-quality data which filtered by special data filtering method and Korean Llama-2 that Korean vocabularis were added. We utilized special data filtering methods which introduced in AlpaGasus to filter high-quality data from mixture of several Korean datasets(OpenOrca-KO, KOpen-Platypus, KoCoT_2000, databricks-dolly-15k-ko). We finetuned Korean Llama-2 that introduced by @beomi on the filtered dataset. The Flash-Attention2 and LoRA were utilized for efficient finetuning.

The finding of KoRAE is as follows:

  1. The finetuning in some epochs showed that high-quality filtered data has positive effects on model's performance. However, finetuning in a few epochs, the quantity of data is more matter than quality. It seems to be due to the lack of performance of the Korean base model. Therefore, the research to improve the Korean base model must continue.
  2. The model trained with DPO showed best performance among KoRAE variants. This shows that DPO is clearly effective in the Korean LLM.
  3. The model finetuned with filtered high-quality KoRAE showed better performance than without. Therefore, for better LLM, we should try to finetune the LLM with high-quality data.

Training Dataset

The KoRAE was finetuned with KoRAE dataset filtered high-quality dataset. This dataset is a combination of the publicly available Koraen dataset and a filtering method was applied to the result of the combination dataset. For more information, please refer to the dataset card of KoRAE.
