Internal Covariate Shift 관련 질문 드립니다.
미해결
딥러닝 CNN 완벽 가이드 - TFKeras 버전
선생님 안녕하세요, 공부를 하던 중 Internal Covariate Shift가 정확히 왜 개선 되어야 하는 문제인지 잘 모르겠어서 이렇게 질문을 남깁니다. 우선 제가 이해한 바로는 Covariate Shift란, 실제 데이터가 True function이라는 분포를 따른다고 할 때 아래와 같은 경우에서 발생한다고 이해했습니다. 우리가 train data를 샘플링 할 때 true function의 큰 틀은 따르지만 조금 다른 분포에서 샘플링을 하고 이를 사용해서 모델을 훈련시킬 경우, 학습 모델은 True function과 전적으로 겹칠 수 없게 됩니다. 따라서 test data를 train data가 커버하고 있지 않는 true function 영역에서 추출하게 된다면 학습시킨 모델은 잘 맞지 않게 될 것이고, 이는 학습용 데이터와 테스트 데이터의 분포가 서로 달랐기 때문에 발생한 문제라고 이해했습니다. Internal Covariate Shift란, 위와 같은 문제가 어떤 레이어의 출력이 다음 레이어의 입력으로 들어갈 때 일어나는걸로 이해했습니다. 딥러닝 특성상 한 레이어당 많은 파라미터가 존재하고 비선형적인 활성화 함수를 사용하기 때문에 A 레이어에 입력이 Z-mean scaling된 데이터가 들어온다고 해도, weighted sum과 활성화 함수를 거쳐서 B 레이어의 입력으로 들어가는 값들은 A 레이어의 정규화된 입력 분포와는 다른 분포를 가지고 있게 될 것입니다. 제가 생각하는 Internal Covariate Shift의 단점은 훈련 속도가 느려진다는 부분입니다. B 레이어의 입장에서는 A 레이어의 가중치 값이 바뀔 때마다 들어오는 입력의 분포가 달라지기 때문에 지속적으로 적응(마땅한 표현이 떠오르지 않네요 ㅠ) 해나가야 해서 결국 최적해를 찾기까지는 오랜 시간이 걸릴 것 같습니다. 이러한 문제는 네트워크가 깊어질수록 입력층에 가까운 레이어와 출력층의 가까운 레이어가 받아보는 분포의 차이는 더 크게 될 것이고, 때문에 입력층에 가까운 레이어의 가중치에서 미세한 조정이 발생해도 출력층에 가까운 레이어의 가중치에서는 상당한 임팩트의 영향력을 끼칠 수 있다고 생각이 되어 네트워크가 안정적으로 수렴하기에 어렵다고 생각됩니다. Training 과정에서는 위와 같은 부분이 문제라고 생각되는데 혹시 제가 잘못 이해한 부분이 있다면 지적 부탁드리겠습니다 선생님. 그리고 문서들을 쭉 찾아보니까 test시에도 training 과정에서 사용했던 분포와 test 할 때 사용하는 이미지 데이터의 분포가 다르기 때문에 성능 차이가 발생한다고 하는데 이 부분이 잘 이해가 안갑니다. 어차피 테스트 할 경우에는 training 할 경우와 세부적으론 다르지만 큰 틀에서는 비슷한 분포의 데이터를 사용하는데, 이러한 gap을 줄여주기 위해 training을 돌리는게 아닌가요? 항상 감사드립니다 선생님. 이와 겹치는 부분이 있지만 결국에는 다른

스크롤을 움직이면 캐릭터가 전진하고 벽이 움직이는 과정에서 렉이 너무 많이 걸립니다. 스크린 크기를 작게한 후 캐릭터랑 벽을 움직여보면 렉이 걸리지 않는데, 풀 스크린 모드에서 캐릭터랑 벽을 움직이면 렉이 너무 많이 걸려서 움직이는 동작을 거의 볼 수 없습니다. 현재 구현하는 기능들이 용량을 너무 많이 차지해서 나오는 문제일까요? 개선 방법을 알고 싶습니다. Chrome 99 on macOS (Monterey) 으로 브라우저 모드를 사용하고 있습니다. 브라우저가 오래된 버전이라 발생하는 문제는 아닌것 같습니다.

안녕하세요 본 강의 15분 55초쯤에서 intent를 선언하는데 this는 작동하지 않고 context라고 입력해야 제대로 작동하는 것을 보았는데요. 지금까지 연습할때도 그렇고 다른 Activity에서도 그렇고 항상 this로 잘 사용을 했었는데 여기서는 context를 입력해야 되는 이유가 무엇인가요? this를 쓰는 것과 context를 쓰는것의 차이를 알고싶습니다!

안녕하세요? 강의 잘 듣고 있습니다. 해당 강의의 SignupForm부분에서 clean_email에 대해 질문입니다. class SignupForm ( UserCreationForm ): def __init__ ( self , *args , **kwargs ) : super (). __init__ ( * args , ** kwargs ) self .fields[ ' email ' ].required = True self .fields[ ' first_name ' ].required = True self .fields[ ' last_name ' ].required = True class Meta ( UserCreationForm .

ValidationError ( " 이미 등록된 이메일 주소입니다. " ) return email 1. 폼이 제출될 때, 모든 폼들의 데이터에 대해 유효성 검사가 완료되고, 완료된 결과가 cleand_data에 딕셔너리 형태로 담기는 것인가요? 2. 유효성 검사가 끝이나고(cleanded_data가 다 종료되고) clean_field 형태의 함수가 자동으로 호출이 되는건가요? 3. 마지막으로 clean_email함수에서 유효성검사가 끝이나면 email을 반환하는데요 반환된 email이 모델폼의 인스턴스, 그러니까 한행의 데이터에 바로 들어가는 로직이 궁금한데, 찾아봐도 잘 모르겠습니다 ㅠㅠ
