안녕하세요! 빅디 입니다.
파일럿 프로젝트 마무리가 얼마 남지 않은것 같습니다. 조금만더 화이팅 해주세요!
실행하신 문제의 원인은 머하웃 명령중 유사도 옵션에서 오타가 있어 보입니다.
[root@server02 pilot-pjt]# mahout recommenditembased -i /pilot-pjt/mahout/recommendation/input/item_buylist.txt -o /pilot-pjt/mahout/recommendation/output/ -s SIMILARITY_COCCURRENCE -n 3
해당 부분의 정확한 명령을 SIMILARITY_COOCCURRENCE 로 입력후 실행해 주세요~
