The dataset with a greater number of features involves more computational cost and it may lead to low performance in the context of prediction accuracy. Therefore, in this research work we have predicted diabetes with more accuracy by using a smaller number of features. The heuristic methods Sequential Forward Selection (SFS), Sequential Backward Selection (SBS) and metaheuristic evolutionary methods\u00a0\u2014 Whale Optimization Algorithm (WOA) and Genetic Algorithm (GA) are used for performing feature subset selection. The Gini index is also used as a filter evaluator. The performance of the feature subsets is analyzed by applying three different types of ML models, Random Forest (RF), Multi-Layer Perceptron (MLP) and K-Nearest Neighbor (KNN). We have predicted type-2 diabetes with an accuracy of 96.82%. Also, we have reduced the number of features up to 67.44% i.e., identified 32.56% most relevant features. <\/jats:p>","DOI":"10.1142\/s1793962324500314","type":"journal-article","created":{"date-parts":[[2024,3,9]],"date-time":"2024-03-09T15:22:03Z","timestamp":1709997723000},"source":"Crossref","is-referenced-by-count":3,"title":["Feature subset selection using heuristic and metaheuristic approaches for diabetes prediction on a binary encoded dataset"],"prefix":"10.1142","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5641-0373","authenticated-orcid":false,"given":"Puneet","family":"Kumar","sequence":"first","affiliation":[{"name":"Department of Computer Science & Engineering, Chandigarh University, Punjab, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8476-2798","authenticated-orcid":false,"given":"Bhoopesh Singh","family":"Bhati","sequence":"additional","affiliation":[{"name":"Department of Computer Science & Engineering, Indian Institute of Information Technology, Sonepat, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2038-7359","authenticated-orcid":false,"given":"Rajesh Kumar","family":"Dhanaraj","sequence":"additional","affiliation":[{"name":"Symbiosis Institute of Computer Studies and Research (SICSR), Symbiosis International (Deemed University), Pune, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4350-3911","authenticated-orcid":false,"given":"Celestine","family":"Iwendi","sequence":"additional","affiliation":[{"name":"School of Creative Technologies, University of Bolton, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2805-4951","authenticated-orcid":false,"given":"Balamurugan","family":"Balusamy","sequence":"additional","affiliation":[{"name":"Shiv Nadar University, Delhi-NCR Campus, Noida, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4812-2280","authenticated-orcid":false,"given":"Nitesh Singh","family":"Bhati","sequence":"additional","affiliation":[{"name":"Department of Computer Science & Engineering, Galgotias University, Greater Noida, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0873-0513","authenticated-orcid":false,"given":"Prerana","family":"Rai","sequence":"additional","affiliation":[{"name":"Chandigarh University, Punjab, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2024,5,31]]},"reference":[{"key":"S1793962324500314BIB001","doi-asserted-by":"publisher","DOI":"10.1016\/j.cam.2019.112571"},{"key":"S1793962324500314BIB002","volume-title":"Handbook of Statistical Analysis and Data Mining Applications","author":"Nisbet R.","year":"2009"},{"key":"S1793962324500314BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2020.106456"},{"key":"S1793962324500314BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.csda.2019.106839"},{"key":"S1793962324500314BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2016.07.026"},{"key":"S1793962324500314BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2020.113981"},{"key":"S1793962324500314BIB007","doi-asserted-by":"publisher","DOI":"10.1016\/j.patcog.2017.11.027"},{"key":"S1793962324500314BIB008","doi-asserted-by":"publisher","DOI":"10.1016\/j.patcog.2015.03.020"},{"key":"S1793962324500314BIB009","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.3047942"},{"key":"S1793962324500314BIB011","doi-asserted-by":"publisher","DOI":"10.1201\/9780429341830"},{"key":"S1793962324500314BIB012","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-34062-8_32"},{"key":"S1793962324500314BIB013","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.3004284"},{"key":"S1793962324500314BIB014","volume-title":"Data Mining: Concepts and Techniques","author":"Han J.","year":"2022"},{"key":"S1793962324500314BIB015","volume-title":"Data Mining: Practical Machine Learning Tools and Techniques","author":"Witten I.
