Cardiovascular Disease Prediction using Recursive Feature Elimination and Gradient Boosting Classification Techniques

Cardiovascular diseases (CVDs) are one of the most common chronic illnesses that affect peoples health. Early detection of CVDs can reduce mortality rates by preventing or reducing the severity of the disease. Machine learning algorithms are a promising method for identifying risk factors. This paper proposes a proposed recursive feature elimination-based gradient boosting (RFE-GB) algorithm in order to obtain accurate heart disease prediction. The patients health record with important CVD features has been analyzed for the evaluation of the results. Several other machine learning methods were also used to build the prediction model, and the results were compared with the proposed model. The results of this proposed model infer that the combined recursive feature elimination and gradient boosting algorithm achieves the highest accuracy (89.7 %). Further, with an area under the curve of 0.84, the proposed RFE-GB algorithm was found superior and had obtained a substantial gain over other techniques. Thus, the proposed RFE-GB algorithm will serve as a prominent model for CVD estimation and treatment.

Forecasting Hyponatremia in hospitalized patients Using Multilayer Perceptron and Multivariate Linear Regression Techniques

The percentage of patients hospitalized due to hyponatremia is getting higher. Hyponatremia is the deficiency of sodium electrolyte in the human serum. This deficiency might indulge adverse effects and also associated with longer hospital stay or mortality, if it wasnt actively treated and managed. This work predicts the futuristic sodium levels of patients based on their history of health problems using multilayer perceptron and multivariate linear regression algorithm. This work analyses the patients age, information about other disease such as diabetes, pneumonia, liver-disease, malignancy, pulmonary, sepsis, SIADH, and sodium level of the patient during admission to the hospital. The results of the proposed MLP algorithm is compared with MLR algorithm based results. The MLP prediction results generates 23-72 of higher prediction results than MLR algorithm. Thus, proposed MLR algorithm has produced 57.1 of reduced mean squared error rate than the MLR results on predicting future sodium ranges of patients. Further, proposed MLR algorithm produces 27-50 of higher prediction precision rate.
