“…The following comparative methods are considered: Adaboost (Liu et al , 2016), SVM (Liu et al , 2016), deep-CNN (Nam and Hung, 2018), GOA-based deep-CNN (Mirjalili et al , 2018) and MFO-based deep-CNN (Mirjalili, 2015) are compared with the proposed MFGHO-based deep-CNN classifier, with respect to the data aggregation strategies, namely, O-SEED + Rider-Cat swarm optimization (RCSO) (Shyjith et al , 2020), genetic spider monkey optimization (GMSO) + spider monkey optimization (SMO) (Soundaram and Arumugam, 2020), TOPSIS + fuzzy multi-criteria clustering and bio-inspired energy efficiency routing (FMCB-ER) (Mehta and Saxena, 2020), FABC + water wave optimization (WWO) (Kumar and Kumar, 2016; Zheng, 2015), protruder optimization, ABC + invasive weed optimization (IWO) (Misaghi and Yaghoobi, 2019; Zheng, 2015), artificial bee colony (ABC) + protruder optimization (Misaghi and Yaghoobi, 2019; Zheng, 2015; Karaboga and Basturk, 2008) and FABC + protruder optimization algorithm [23] (Misaghi and Yaghoobi, 2019; Zheng, 2015).…”
