Embodiment Construction
[0090] The technical problem to be solved by the present invention is to provide a machine learning-based pre-pregnancy and pregnancy Screening Methods for Down Syndrome in Intermediate Stage.
[0091] The specific steps of the machine learning-based screening method for Down's syndrome in the first trimester and the second trimester of the present invention are as follows:
[0092] Step 1. Data Acquisition
[0093] The data used in the present invention comes from the clinical diagnosis records of the First Affiliated Hospital of Jilin University. The content of the data is 100,138 screening results of Down’s syndrome in the second trimester of pregnancy, with a total of 58 fields. After cleaning, 81,626 samples were obtained. The present invention tests the performance of the predictive model when selecting different attributes for the feature vectors. The results show that when the three fields "AFP Conc.", "hCGbConc.", and "uE3Conc." are used as training features, the ac...
