Large　for　gestational　(LGA)　means　the　fetus　having　an　abnormal　birth　weight.　It　adheres　severe　complications　during　and　after　the　maternal　period.　Therefore,　this　research　presents　an　ensemble　classification　scheme　using　Chinese　National　Pre-Pregnancy　Examination　Program　dataset　to　classify　a　fetus　as　an　LGA　or　non-LGA　based　on　provided　Chinese　LGA　classification　guidelines.　Moreover,　the　proposed　scheme　is　comprised　of　data　cleansing　and　ensemble　classification　schemes　that　have　drastically　improved　the　LGA　classification　process　with　improved　performance　results　compared　to　present　published　studies.　Therefore,　the　recommended　scheme　can　be　utilized　by　healthcare　professionals　to　build　an　enhanced　and　reliable　LGA　classification　system.　©　2020　IEEE.
