Each image is of shape (width, height, 3), where 3 is for the 3 channels (RGB). Given a training set of m_train images labeled as "cat" (y=1) or "non-cat" (y=0), and a test set of m_test images labeled as cat or non-cat, show the steps for a simple image-recognition algorithm that can correctly classify pictures as cat or non-at.
