To further analyze the proposed algorithm, we evaluate the selected features by FO-MPA by performing classification. Medical imaging techniques are very important for diagnosing diseases. According to the formula10, the initial locations of the prey and predator can be defined as below: where the Elite matrix refers to the fittest predators. We adopt a special type of CNN called a pre-trained model where the network is previously trained on the ImageNet dataset, which contains millions of variety of images (animal, plants, transports, objects,..) on 1000 classe categories. Layers are applied to extract different types of features such as edges, texture, colors, and high-lighted patterns from the images.
