機械学習で階層/ネストされたデータを処理する方法
例で問題を説明します。いくつかの属性(年齢、性別、国、地域、都市)を与えられた個人の収入を予測するとします。あなたはそのようなトレーニングデータセットを持っています train <- data.frame(CountryID=c(1,1,1,1, 2,2,2,2, 3,3,3,3), RegionID=c(1,1,1,2, 3,3,4,4, 5,5,5,5), CityID=c(1,1,2,3, 4,5,6,6, 7,7,7,8), Age=c(23,48,62,63, 25,41,45,19, 37,41,31,50), Gender=factor(c("M","F","M","F", "M","F","M","F", "F","F","F","M")), Income=c(31,42,71,65, 50,51,101,38, 47,50,55,23)) train CountryID RegionID CityID Age Gender Income 1 1 1 1 23 M 31 2 1 1 1 48 F 42 3 1 1 2 62 M 71 4 …
