Abstract‘Curse of Dimensionality’—massive generation of high-dimensional medical datasets from various biomedical applications hardens the data analytic process for precise medical diagnosis. The design of an efficient feature selection technique for finding the optimal feature subset can be devised as a prominent solution to the above-said challenge. Further, it also improves the accuracy and minimizes the computational complexity of the learning model. The state-of-the-art feature selection techniques based on heuristic and statistical functions suffer from significant challenges in terms of classification accuracy, time complexity, etc. Hence, this paper presents Rough Set Theory and Hypergraph (RSHGT)-based feature selection technique to identify the optimal feature subset for accurate medical diagnosis. Experimental validations using six medical datasets from the Kent Ridge Biomedical dataset repository prove the efficiency of RSHGT in terms of reduct size, accuracy, precision, recall, and time complexity.
