미해결[개정판] 파이썬 머신러닝 완벽 가이드
get_cost 함수 w1[0,0]가 들어가는 이유
안녕하세요 강사님 수업 잘 듣고있습니다!파이썬 코드로 경사 하강법 구현하기에서 def get_cost 함수 y_pred = w1[0,0] * X + w0 부분에 질문이 있습니다.현재 코드가 w1와 w0 둘다 shape이 (1,1)이라서 그런지 더욱 헷갈리는 것 같습니다. 왜 w1[0,0]가 들어가고, w0은 전체가 들어가는지 정확하게 이해가 되지 않습니다.y_pred = w1 * X + w0 이렇게 넣어도 반환되는 값은 똑같은데 만약 feature가 여러 개가 있어도 똑같이 w1[0,0]을 넣는 것인지 아니면 그거랑 상관없이 다르게 이해하고 있는 것인지... 잘 모르겠습니다!

해결됨[코드캠프] 부트캠프에서 만든 고농축 백엔드 코스
Entity 구현 - 1: N, N : M 이 강의10분 13초에서
안녕하세요.위 파일은 product.entity.ts 파일입니다.product.entity.ts 파일에서 @JoinColumn() 을 productSaleslocation 테이블에만 해주시는 이유가 무엇인지 알 수 있을까요?product테이블과 서로 관계를 맺고 있는 productSaleslocation 테이블과 users 테이블에도 @JoinColumn()을 해줘야 하는 것 아닌가요?상품테이블은productCategory테이블과(상품카테고리_id)ManyToOne 관계를 맺고 있으며, User 테이블과 (유저_id) ManyToOne 관계를 맺고 있어서 각각 JoinColumn을 해줘야 하는 것으로 생각했는데, 제 생각이 틀린 것일까요?좋은 강의 해주셔서 진심으로 감사합니다!

@mixin 파트 시청중 궁금점이 생겨서요!첫번째 이미지 처럼 hover를 저렇게주고 css 컴파일하면은두번째이미지처럼 3개의 hover를 가진 css로 컴파일 되어서 보여지는데요.저러면은 괜히 css만 지저분해져보이는데 저렇게 hover를 주는 이유가 있었을까여?.그리고 css 컴파일 된것을 보면은ex) .complete.complete:hover -> 이렇게 되어있으면은 제가 알고 있는 css개념으로는.complete 클래스를 가지면서 .complete를가진 요소에 hover를 줘라라고 알고있기때문에hover가 먹지 않을꺼라고 생각이들었는데요. 먹어지는 이유가 있을까요?..

코드 작성 후, 리로드하면 웹브라우저에서 코딩이 그대로 실행됨
처음에는 태그 자동완성도 되고 리로드도 정상적으로 실행됐습니다.그런데 수강 중 실습하면서 코딩 작성하다가 알림창이 떠서 확인도 안하고 클릭했더니다음부턴 태그 자동완성도 안되고, 웹브라우저로 리로드하면 원본 코드 그대로 나타납니다...visual studio code 삭제 이후 재설치해봤는데도 똑같은 상태라서 어떻게 해야할지 모르겠습니다.
