안녕하세요 제로초님 강의 듣던중 해결이 안되는 부분이 있어 질문 드려요ㅜ로그인을 하면 redux tool 에도 LOG_IN_SUCCESS가 잘 뜹니다 또한 network에서 login 200으로 잘 찍히구요 그러나 아래의 에러가 뜨며 진행이 되지 않습니다 ㅜ const fullUserWithoutPassword = await User.findOne({         where: {id: user.id},         attributes: {           exclude: ['password']         },         include: [{           model: Post         }, {           model: User,           as: 'Followings'         }, {           model: User,           as: 'Followers'         }]     }) password만 제외하고 불러오는 코드도 작성했는데  무슨문제인지 몰라서 질문드려요 ㅜ 구글링도 해보고 질문 게시판도 봤는데 무슨 문제인지 모르겠습니다ㅜ

#include <stdio.h> int main() { int a, b, c, max = 0; scanf_s("%d %d %d", &a, &b, &c); if (a > b && a > c) { max = a; if (b + c < a) { printf("NO"); } else { printf("YES"); } } else if (b > a && b > c) { max = b; if (a + c < b) { printf("NO"); } else { printf("YES"); } } else if (c > a && c > b) { max = c; if (a + b < c) { printf("NO"); } else { printf("YES"); } } return 0; } 제 코드가 너무 더럽게 나와서 별로 보기싫긴한데 처음에 풀때 이렇게 나왔는데 이렇게 풀어도 맞는건가요?

우선 인생 강의 정말 감사드립니다. 도움이 정말 많이 되네요ㅠ,ㅠ 강의 시간과 분량 상 필수적이고 핵심적인 것만 알려주셨을 거 같은데, 강의에서 가르쳐주신 것처럼 자기만의 서버 프레임워크를 만들어갈 때 더 추가할 만한 기능이 있을까요?    

#include <stdio.h> int main() { int a; scanf_s("%d", &a); if (a % 2 == 0 && a != 0) { printf("even\n"); } else if (a == 0) { printf("zero\n"); } else { printf("odd\n"); } return 0; } 이런식으로 코드를 만들었는데 이것도 답은 똑같이 나오는데 혹시 정확히 맞는 답이 아닌가요?

안녕하세요. 이번 강의에서 multi thread 환경에서 thread가 사용하는 process 의 메모리 영역에 대한 그림에 질문드립니다. 저번강의에서 thread는 process의 stack 영역을 제외하고 heap, data, code 영역은 공유한다고 들었는데 이번 강의 그림에는 code1,code2,code3이 분리가 되어있습니다. 프로세스 단위로는 code1,2,3 구분이 무의미하고 multi thread 단위 입장에서는 각각 다른 code를 수행할 수도 있고 같은 code를 수행할 수도 있지만 독립적인 단위라는 개념상 code를 분리하신거라고 이해하면 될까요?     

안녕하세요. 캡틴판교님 남겨주신 답변을 참고해서 타입스크립트의 ESlint설정을 따라해보았지만 오류가 자꾸 잡혀서   npm install eslint --save-dev eslint --init √ How would you like to use ESLint? · style √ What type of modules does your project use? · esm √ Which framework does your project use? · vue √ Does your project use TypeScript? · Yes √ Where does your code run? · browser √ How would you like to define a style for your project? · guide √ Which style guide do you want to follow? · airbnb √ What format do you want your config file to be in? · JavaScript Checking peerDependencies of eslint-config-airbnb-base@latest The config that you've selected requires the following dependencies: eslint-plugin-vue@latest eslint-config-airbnb-base@latest eslint@^7.32.0 || ^8.2.0 eslint-plugin-import@^2.25.2 √ Would you like to install them now with npm? · Yes다음과정을 거쳐서 eslint를 설치하고 판교님의 깃헙을 참고해서.eslintrc.js의 extends에 'plugin:@typescript-eslint/eslint-recommended' 속성을 추가해서 해결했는데 이 플러그인이 무슨의미인지 알고 싶네요. .eslintrc파일 코드 첨부하겠습니다 module.exports = { env: { browser: true, es2021: true, }, extends: [ 'plugin:@typescript-eslint/eslint-recommended', // 추가 'plugin:vue/essential', 'airbnb-base', ], parserOptions: { ecmaVersion: 'latest', sourceType: 'module', }, plugins: ['vue'], rules: { 'linebreak-style': 0, }, };

항상 좋은 강의와 답변 제공해주셔서 감사합니다. 쉽고 명료한 설명 덕분에 무사히 완강할 수 있었습니다. 수업을 마치며 몇가지 질문이 있어서 드립니다!!   1. 새로운 커스텀 데이터에 Masking 에 대한 Annotation 은 어떻게 만드나요?? 이전에 BBox Annotation 제작했었던 것처럼 cvat를 이용해서 만들 수 있는지, 아니면 다른 방법으로 만드는지 궁금합니다.   2. 현재 DLCV 관련 분야로 취직을 목표로 하고 있습니다. 허나 비전공자로서 혼자 공부를 하다보니 방향을 잡기가 좀 힘든 것 같습니다. 대학원같은 경우는 현재 상황상 불가능하여 우선은 배운 것을 바탕으로 캐글같은 컴페티션 경험이나 DLCV 관련 논문을 읽고 구현해보는 경험을 쌓아볼까 하는데, 선생님께서 생각하시기에는 어떤 내용을 추가적으로 공부하면 좋을지 어떤 방향으로 경험과 실력을 쌓아가는 것이 좋을지 자문을 구하고 싶습니다.   3. AutoML과 같은 패키지들을 DLCV 관련 현업에서도 사용하는지 궁금합니다. 뭔가 현업에서는 자신들의 목적에 맞게 모델을 직접 만들 것 같은데 실제로 어떠한지 알고싶습니다. 혹시 현업에서 모델을 직접 만든다면 그러한 능력을 키우고 경험을 쌓아두어야할지 궁금합니다.  

You will most likely be unable to trade cryptographic money until you complete the check cycle. The stage might request that you present a duplicate of your driver's permit or identification, and you might even be approached to transfer a selfie to demonstrate your appearance matches the reports you submit. To purchase crypto, you'll have to ensure you have buy cryptocurrency coins assets in your record. You could store cash into your crypto account by connecting your ledger, approving a wire move or in any event, making an installment with a charge or Mastercard. Contingent upon the trade or specialist and your subsidizing strategy, you might need to stand by a couple of days before you can utilize the cash you store to purchase digital money.

안녕하세요 스프링 김영한님 커리 타고 있는 학생입니다. 계속 강의를 들으며, 필기하고 같이 코드를 따라 치고 있는 중인데 막상 제거가 되지 않는 느낌이어서요.. 특히 스프링같은경우는 클래스들을 객체화 시키는 과정이 중요한 것 같은데, 막상 코딩을 하려고 하면 못하는 것 같습니다. 혹시 공부 방법좀 여쭤볼 수 있을까요

json 정보들이 존재하는 uri에 delete요청을 보내면 해당 json 리소스들이 삭제되는 것인가요 아니면 body 부분 필드들만 모두 삭제가 되는건가요?

이제는 MyView나 ModelView 이런거 없이 SpringMemberControllerV3.java 이것만 있으면 되는건가요?   

intellij 사용중입니다. 캡쳐에서 보시다시피 다른 function이나 method들은 잘 나오는데 mongoose.connect만 왜 .. unresolved function or method 라고 나오는걸까요 ㅠㅠ 에러는 아니지만 신경이쓰여서 질문남깁니다..

강의보면  .......................... org.hibernate.SQL select    order0_.order_id.......   이렇게 친절하게 개행된 쿼리가 나오는데 저는 안나오네요 아래는 설정화면 입니다. 생각해보니 강의 3개째보는데 개행된 쿼리는 나온적이 없어요. 혹시 인텔리제이 커뮤니티 버전이라서 그런걸까요?      

분류 모델에서 정확도는 미분이 안되어 손실 함수로 쓸 수 없기 때문에 손실 함수는 회귀 모델에서 주로 쓰이고 분류 모델에서 정확도를 평가하기 위해서는 정확도 대신 로지스틱 손실 함수를 사용한다고 하셨는데, 분류 모델을 정확도로 평가하지 않고 굳이 로지스틱 손실 함수를 사용하여 z값을 바꿔 확률값을 측정하는 이유가 뭔가요?! 경사하강법을 통해 더욱 정확한 값을 예측하기 위해서인 건가요?
