Abstract

This study examined an efficient model for the accurate prediction of blood pressure levels by building on existing models that are useful for HBP prediction. The best model was selected based on RMSE and MAE evaluation metrics that were used to evaluate their performance. The RMSE metric was used to provide information by doing a term-by-term comparison and showing the value-performance relationship between selected models; while the MAE metric shows the average of absolute errors that the selected models are liable. The data for this study was sourced from Kaggle.com because it is publicly available and reduces the chance for ethical misconduct. Features of the data selected are useful for training, testing, and estimation of the study outcome. This was done through the processes of pre-cleaning, visualisation, transformation, engineering, and modelling. The Cat-Boost model outperformed other models with an RMSE score of 7.307459 and an MAE score of 5.790854; this was further confirmed after evaluation by the Grid search presented good evaluation scores where the RMSE and MAE scores were significantly reduced to 0.87773 and 0.12256 respectively. The study also shows that the most significant variable for blood pressure measurement is age while the least significant is the number of major vessels coloured by fluoroscopy (ca 4).
