미해결캐글 Advanced 머신러닝 실전 박치기
주피터 노트북 설정 변경과 관련하여 질문 좀 드립니다
안녕하세요~ 영상 설명대로 주피터 노트북 설정을 변경하면 구글 클라우드를 사용하지 않고 제 컴퓨터 상에서 주피터 노트북을 이용하더라도 설정이 이전과 달라지는 게 맞나요? 만약 맞다면, 혹시 영상 설명대로 주피터 노트북 설정을 하면서 기존 주피터 노트북의 설정도 유지할 수 있는 방법이 있나요? 구글 클라우드를 경험해보고 싶어서 순서대로 영상을 보며 진행하고 있었는데, 기존 주피터 노트북 설정을 바꿔야 하는 것 같아 코랩을 써야할지 고민이 되네요 ><

판매 컨트랙트 팩토리 패턴
안녕하세요 좋은 강의 잘 봤습니다! 강의를 보고 궁금한 게 있어 질문 드립니다. 강의에서는 1개의 판매 컨트랙트로 거래를 관리하는 것 같은데, 팩토리 패턴으로 각 거래마다 새로운 컨트랙트를 생성해서 관리하는 방법도 있는 것 같더라구요. 이와 비교해서 1개의 판매 컨트랙트로 관리했을 때의 문제점은 없는걸까요? 그리고 대중적으로 어떤 방법이 많이 쓰이는지 궁금합니다!

미해결[리뉴얼] 파이썬입문과 크롤링기초 부트캠프 [파이썬, 웹, 데이터 이해 기본까지] (업데이트)
수업응용해서 질문있습니다.
해당 수업을 듣고 if 문을 활용하여 문장을 구성해봤는데, 실행이 되질 않습니다. import requests from bs4 import BeautifulSoup res = requests.get('https://davelee-fun.github.io/') soup = BeautifulSoup(res.content, 'html.parser') items = soup.select('h2.text-dark') items2 = soup.select('h4.card-text') for item in items: if item == '매트리스커버 관련 상품 추천': for item2 in items2: print(item2.get_text()) items가 만약 매트리스 커버 관련 상품추천인 경우에 상품명을 추출하는 로직을 짜고 싶은데, items가 리스트형태로 하나, 하나씩 item으로 들어간다고 생각해서 if문을 item으로 엮었고, 이후에는 상품명을 출력하기위해서 for문을 사용하였습니다. 어떤 부분이 잘못되었는지 혹은 이런 로직을 짜려고하면 어떻게 해야하는지 알려주실 수 있나요?? (만약 질문의 범위에서 벗어난 것이라면 벗어났다고만 답변드려도 됩니다.)

Internal Covariate Shift 관련 질문 드립니다.
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

1. Debug.Log나 텍스트에서 변수를 출력할 때 $를 쓰시던데 그냥 문자열 뒤에 +로 변수를 붙이는 거랑 성능상 차이가 있나요? 아니면 그냥 선호하는 스타일의 차이인가요? ex)$"점수 : {_score}" / "점수 : " + _score; 2. 유니티 최적화 관련 글을 읽어보면 대부분 Resources폴더 및 Resources.Load()를 사용하는게 메모리 관리나 최적화에 안 좋다는 얘기를 하던데 현재 강의에서 만드는 게임은 규모가 작으니 괜찮다고 해도 앞으로 직접 본인만의 게임을 만들거나 할 때는 이 방식을 그대로 써도 괜찮은지 궁금합니다.
