Stroke Prediction Model Based on XGBoost Algorithm
International Journal of Applied Sciences & Development, 2022In this paper, individual sample data randomly measured are preprocessed, for example, outliers values are deleted and the characteristics of the samples are normalized to between 0 and 1. The correlation analysis approach is then used to determine and rank the relevance of stroke characteristics, and factors with poor correlation are discarded.
