1	Label	According to the police, shares of Nature Cell jumped to 62,200 won, once in the 4,000 won range, but their shares fell sharply in March after the Ministry of Food and Drug Safety rejected the request for conditional permission from Jointstem
2	Google Translation	According to the police, the stock price of Nature Cell, which was once in the 4,000 won range, soared to a maximum of 62,200 won, but the stock price fell sharply after the Ministry of Food and Drug Safety rejected JointStem's conditional permit application in March.
2	koBART	According to the police, shares of Nature Cell, which were once around 4,000 won, jumped to up to 62,200 won, but shares fell sharply in March when the Ministry of Food and Drug Safety rejected the conditional licensing application of Joint System.

Model Performance

• Test Data에서 임의의 10,000개 데이터를 추출하여 BLEU Score를 산출함

BLEU
32.85

Demo

• 학습한 model binary 추출 작업이 필요함
  • pytorch-lightning binary --> huggingface binary로 추출 작업 필요
  • hparams의 경우에는 ./logs/tb_logs/default/version_0/hparams.yaml 파일을 활용
  • model_binary 의 경우에는 ./logs/kobart_translation-model_chp 안에 있는 .ckpt 파일을 활용
  • 변환 코드를 실행하면 ./translation_binary 에 model binary 가 추출 됨

 python get_model_binary.py --hparams hparam_path --model_binary model_binary_path

• streamlit을 활용하여 Demo 실행
  • 실행 시 http://localhost:8501/ 로 Demo page가 실행됨

streamlit run infer.py

• Demo Page 실행 결과
  • 원문링크
