개요

본 논문은 기울기 기반 이중 수준 최적화(gradient-based bilevel optimization)의 효율성을 개선하는 Mixed-Flow Meta-Gradients (MixFlow-MG) 알고리즘을 제안합니다. 기울기 기반 이중 수준 최적화는 하이퍼파라미터 최적화, 작업 적응, 알고리즘 발견, 메타러닝 등 다양한 분야에 활용되지만, 기울기의 기울기를 계산하는 과정에서 계산 비용이 높은 2차 및 혼합 도함수를 필요로 합니다. MixFlow-MG는 혼합 모드 미분을 사용하여 더 효율적이고 확장성 있는 계산 그래프를 구성하여 기존 구현 방식보다 메모리 사용량을 10배 이상, 벽시계 시간을 최대 25%까지 단축합니다.
