Abstract: Small for Gestational Age (SGA) and Large for Gestational Age (LGA) describe fetuses whose weights deviate below or above the expected average for their gestational age (24 to 42 weeks). SGA fetuses typically fall below the 10th percentile in weight, indicating intrauterine growth restriction, while LGA fetuses surpass the 90th percentile, signifying excessive growth. Accurate classification of SGA and LGA is crucial for evaluating fetal health and guiding prenatal care decisions. This study proposes a Weighted Soft Voting Ensemble Classifier (WSVEC) capable of predicting these classifications by the end of the first trimester.
