연관규칙 분석
연관규칙 분석이란 특정한 사건이 발생했을 때 동시에 발생하는 또 다른 사건과의 규칙을 찾아ㅐ는 분석 방법
남성고객이 맥주와 기저귀를 함께 구매하는 경향이 크다는 사실을 밝혀내어 상품 배치에 활용한 사례 유명
장바구니 분석이라고도 함
지지도, 신뢰도, 향상도가 중요 지표로 활용됨
지지도(support): 사건이 데이터에서 나타나는 비율
비율을 높일수록 선택되는 사건은 적어짐
비율을 낮출수록 중요하지 않은 사건이 나타남
0.001(0.1%) ~ 0.01(1%)로 시작해 본다
신뢰도(confidence): 규칙이 맞을 확률
비율을 높일수록 중요한 규칙들만 나타남
비율을 낮출수록 많은 규칙들이 나타남
0.8(80%) ~ 0.9(90%)로 시작해 본다
향상도(Lift): 두 규칙의 상관관계
사건 Y의 확률대비, 사건 X가 발생할 때 사건 Y가 발생할 확률
향상도가 크면 우연적일 가능성이 적다는 의미임
