“…To test the performance of the designed model, different brain tumor data sets have been used by researchers Abbas et al, 2018b;Saba et al, 2019) Fatima, Rehman, Almazyad, & Saba, 2017;Jamal et al, 2017;Mughal, Muhammad, et al, 2017a;Mughal, Muhammad, Sharif, Rehman, & Saba, 2018;Mughal, Sharif, et al, 2017b;Muhsin, Rehman, Altameem, Saba, & Uddin, 2014;Rad, Rahim, Rehman, Altameem, & Saba, 2013;Waheed et al, 2016). Such models include encoder-decoder models (Castillo et al, 2017;Saba, 2018;Saba, Rehman, & Sulong, 2011a;Sharif et al, 2017), multiple networks to extract the different level of features (Sedlar, 2017), models using convolutional networks with some postprocessing (Shaikh et al, 2017) and hybrid architectures with varying numbers of layers (Mundher, Muhamad, Rehman, Saba, & Kausar, 2014;Neamah, Mohamad, Saba, & Rehman, 2014;Saba & Alqahtani, 2013).…”
