“…From the literature reviewed, it was observed that many studies have applied diverse deep learning techniques in addressing classification problems, among the approaches is Alex.Net which has been trained with several datasets and evaluated. The results despite the success revealed certain gaps such as occlusion in [78], the need for improved sensitivity in [79], and delay when applied for real-time classification in [70, 75 and 80]. In the case of Mobile-Net, which has also been tested on several datasets, overall results need improvement in [15,16], lack of instructiveness was identified in [68, 69 and 84] as the gap.…”
