Its symptoms are not known at an early stage due to which a person is deprived of receiving medication at an early stage. Dementia, a general form of Alzheimer, is difficult to diagnose and hence a proper system for detection of Alzheimer is needed. Various studies have been done for accurate classification of patients with or without Alzheimer\u2019s disease (AD). However, accuracy of prediction is still a challenge depending on the type of data used for diagnosis. Timely identification of true positives and false negatives are critical to the diagnosis. This work focuses on extraction of optimal features using nature-inspired algorithms to enhance the accuracy of classification models. This work proposes two hybrid nature-inspired algorithms\u00a0\u2014 particle swarm optimization with genetic algorithm (PSO_GA) and whale optimization algorithm with genetic algorithm, (WOA_GA) to improve prediction accuracy. The performance of proposed algorithms is evaluated with respect to various existing algorithms on the basis of accuracy and time taken. Experimental results depict that there is trade-off in time and accuracy. Results revealed that the best accuracy is achieved by PSO_GA while it takes higher time than WOA and WOA_GA. Overall WOA_GA gives better performance accuracy when compared to a majority of the compared algorithms using support vector machine (SVM) and AdaSVM classifiers.<\/jats:p>","DOI":"10.1142\/s146902682250016x","type":"journal-article","created":{"date-parts":[[2022,8,6]],"date-time":"2022-08-06T03:00:55Z","timestamp":1659754855000},"source":"Crossref","is-referenced-by-count":6,"title":["Hybrid Nature-Inspired Algorithm for Feature Selection in Alzheimer Detection Using Brain MRI Images"],"prefix":"10.1142","volume":"21","author":[{"given":"Parul","family":"Agarwal","sequence":"first","affiliation":[{"name":"Jaypee Institute of Information Technology, Sector \u2013 62, Noida 201301, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anirban","family":"Dutta","sequence":"additional","affiliation":[{"name":"Jaypee Institute of Information Technology, Sector \u2013 62, Noida 201301, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tarushi","family":"Agrawal","sequence":"additional","affiliation":[{"name":"Jaypee Institute of Information Technology, Sector \u2013 62, Noida 201301, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikhil","family":"Mehra","sequence":"additional","affiliation":[{"name":"Jaypee Institute of Information Technology, Sector \u2013 62, Noida 201301, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shikha","family":"Mehta","sequence":"additional","affiliation":[{"name":"Jaypee Institute of Information Technology, Sector \u2013 62, Noida 201301, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,8,3]]},"reference":[{"key":"S146902682250016XBIB001","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1016\/j.trsl.2018.01.001","volume":"194","author":"Liu X.","year":"2018","journal-title":"Transl.
