Abstract
The feature selection method is a learning acquisition technique that selects the most pertinent features. Feature selection aims to reduce computational overload and improve the classifier by enumerating essential features. The presence of replicate and unimportant features in an extensive data set can dramatically reduce the efficiency of machine learning models. This paper proposes an efficient feature selection algorithm for healthcare data using recursive feature elimination with feature ranking (RFE_FR) to improve classification performance. The different feature ranking methods, including info gain, relief, and correlation-based ranking approaches, are used to compute the feature rank. It reduces the feature dimension and selects features efficiently. This approach improves performance by removing associated and redundant features from the dataset. To investigate the RFE_FR performance, the machine learning classification algorithms KNN, NB, RF, and SVM are employed. The accuracy of the suggested method performance is assessed using the real-time healthcare dataset. This study demonstrates that, when comparing the model efficiency with and without feature selection, the RFE_FR strategies selected have a significant favourable effect on the model performance.
