[창의 퍼즐] 수학의 머신러닝공식

수학에는 여러가지 학문이 있지만 당최 머신러닝 공식이란것은 찾아보기힘들다

일반 기계적머신러닝은

(AI입문서저서 참고) 크림빵, 단팥빵, 시나몬롤, 초코칩쿠키, 소시지빵, 피자빵

이있을때 크림빵의 음료수선택은 보통 우유가많다

어떤식으로 결정을하냐면 어떤사람이 크림빵에 우유를 구매하였다 라고 가정하게된다면

우유가중치에 1을더한다 하지만다른 음료를 구매할때는 우유가중치를 포함한 다른가중치에 -1을 한다(0보다크다면) 그리고 그 구매한음료의 가중치에 1을더하여

확률을 결정하는방법으로 쓰입니다

기계적머신러닝을 수학공식으로 표현하게된다면

$f(x,y, a_1, a_2,a_3) = a_x++, (\sum_{k = 1}^{3} (a_k--, a_x++)+a_x--)$ (제가만든거) x는 음료매개변수, y는 빵매개변수, a_i는 음료가중치 a_1 은 우유의가중치 a_2는 커피의가중치 a_3은 사이다의 가중치 여기서는 시그마가 for반복문으로 쓰이며, ++, --는 각각 1을 더하다, 1을 빼다입니다

이제 여러분들이 해야할차례입니다

이 머신러닝공식에서 IF를 쓰지않고 위 기계적머신러닝 함수를 이용해 수학공식으로 음료를 추천해주십시오!

그러면 이는 이차원배열의 형태를 띄우게 되겠죠
