Retraction: Optimal brain tumor diagnosis based on deep learning and balanced sparrow search algorithm

Abstract

Liu T, Yuan Z, Wu L, Badami B. Optimal brain tumor diagnosis based on deep learning and balanced sparrow search algorithm. Int J Imaging Syst Technol. 2021;31:1921–1935. https://doi.org/10.1002/ima.22559The above article, published online on 22 February 2021 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor‐in‐Chief Dr. Mohamed Seghier, and Wiley Periodicals, LLC. The retraction has been agreed due to major overlap between this article and the following article by the same group of authors: Liu T, Yuan Z, Wu L, Badami B. An optimal brain tumor detection by convolutional neural network and Enhanced Sparrow Search Algorithm. Proc Inst Mech Eng H., J. Med. Eng 2021;235:459–469. https://doi.org/10.1177/0954411920987964. Following an investigation by the editorial office and Wiley, it was determined that the degree of overlap between these two articles constitutes a duplicate publication, which violates the journal's and Wiley's policies.
