“…A state-of-the-art survey paper summarizes the research achievements about the fusion of deep learning and fuzzy systems in recent years, and represents the overall framework and graphical form of fusing deep learning and fuzzy systems, as well as some challenges and future research . Especially, fuzzy deep learning has been applied to handle uncertain medical data, e.g., images (Amaya-Rodriguez, Duran-Lopez et al 2019, Ramirez, Sanchez et al 2019, Mohebbian, Hassan et al 2020, Huang, Zhang et al 2021), text records (Davoodi and Moradi 2018, Gangavarapu, Jayasimha et al 2019, Li, Wei et al 2021, Poli, Ouerdane et al 2021) and video files (Lawanot, Inoue et al 2019, Fathabadi, Grantner et al 2021, Verma and Dubey 2021, for different effects, segmentation (Chouhan, Kaul et al 2018, Sevik, Karakullukcu et al 2019, classification (Luo, Pan et al 2020, Zhuang, Kang et al 2020, natural language processing (Davoodi andMoradi 2018, Gangavarapu, Jayasimha et al 2019), prediction (Jiang, Li et al 2021, Nguyen, Kavuri et al 2022) and fusion (Hermessi, Mourali et al 2019, Vinnarasi, Daniel et al 2021 This paper aims to review fuzzy deep learning for uncertain medical data. The main contributions of the paper are listed as follows: 1) constructing four types of frameworks of fuzzy deep learning methods used for uncertain medical data; 2) making a survey of fuzzy deep learning for uncertain medical data, including widely-used fuzzy deep learning methods, uncertain medical data and effects; 3) exhibiting evaluation metrics considering classification, segmentation and fusion; 4) providing some critical discussions on advantages, challenges and future research directions of fuzzy deep learning for uncertain medical data.…”
