*3.3. Performance Metrics*

As noted in Section 1, the possibility for bias arises when only a few metrics are reported while other notable metrics remain unreported [3]. Since each metric reports different information regarding an algorithm's performance, some articles tend to only report those metrics that reflect their method's improved performance while shunning others. However, to avoid such unacceptable practices, we used a variety of notable metrics to compare the different models with aim to provide a broader perspective regarding the performance of the different models. To this effect, five well-known evaluation metrics were considered, and they are discussed as follows.
