# lora-midm-nsmc

This model is a fine-tuned version of [KT-AI/midm-bitext-S-7B-inst-v1](https://huggingface.co/KT-AI/midm-bitext-S-7B-inst-v1) on an nsmc dataset.

## Model description

KT-midm model을 nsmc데이터를 활용하여 미세튜닝한 모델  
영화 리뷰 데이터를 기반으로 사용자가 작성한 리뷰의 긍정 또는 부정을 파악한다.  


## Intended uses & limitations

### Intended uses
사용자가 작성한 리뷰의 긍정 또는 부정 감정 분석을 제공함

### Limitaions
영화 리뷰에 특화되어 있으며, 다른 유형에는 제한이 있을 수 있음  
Colab T4 GPU에서 테스트 되었음

## Training and evaluation data

Training data: nsmc 'train' data 중 상위 2000개의 샘플
