Improved Clinical Diagnosis Using Predictive Analytics

Abstract

The strength of Predictive analytics lies in the ability to reveal interesting patterns obscured within the data and aid the decision-making process. Predictive analytics when deployed using high-end techniques, tools, and methods plays a significant life savior role in the early detection and diagnosis of several human diseases. This research work proposes implementation of predictive analytics using a multi-stratified algorithm named the “Local Weight Global Mean K-Nearest Neighbor (LWGMK-NN)” algorithm under the supervised classification category built over the foundation of analytical techniques without any preset assumptions to discover insights and make predictions. We have considered ten standard clinical datasets to demonstrate the performance of the proposed work against nine state-of-the-art classification algorithms: Logistic Regression, Decision trees, Gaussian Naive Bayes, Random Forest, Linear Support Vector Machine, Stochastic Gradient Descent, Artificial Neural Networks, and XGBoost as benchmark algorithms. Experimental results shown through performance metrics obtained for simple random sampling, 5-fold cross-validation- a statistical re-sampling method, and for 5 times iterated 5-fold cross-validation techniques concludes the efficiency of the LWGMK-NN algorithm and justifies its implementation as a predictive model.
