Maskinlærings-augmenteret afbrudt tidsserieanalyse

Maskinlærings-augmenteret afbrudt tidsserieanalyse (ML-ITS) estimerer den kausale effekt af en diskret intervention ved at træne en maskinlæringsmodel på tidsseriedata før interventionen, projicere en kontrafaktisk bane ind i perioden efter interventionen og måle afstanden mellem observerede og forudsagte resultater. Den udvider klassisk ITS ved at erstatte parametriske trendantagelser med fleksible ML-estimatorer såsom gradient boosting, random forests eller Bayesianske strukturelle tidsseriemodeller.
