대구 교통사고 피해 예측 AI 경진대회

경진대회 개요

  1. 사고 발생 시간, 공간 등의 정보를 활용하여 사고위험도(ECLO)를 예측하는 AI 알고리즘 개발

     ECLO(Equivalent Casualty Loss Only) : 인명피해 심각도
     - ECLO = 사망자수 * 10 + 중상자수 * 5 + 경상자수 * 3 + 부상자수 * 1
     - 본 대회에서는 사고의 위험도를 인명피해 심각도로 측정
    
  2. 평가 방법 : RMSLE(Root Mean Squared Logarithmic Error) of ECLO

참여자

빅데이터 연합동아리 Bitamin 12기 구준회, 김지원, 서은서, 송규헌, 최시훈

결과

  • RMSLE : 0.42706
  • 리더보드 상위 5%
