Such that provided an image or images I can easily classify within its category. Most approaches that search through training data for empirical relationships tend to overfit the data, meaning that they can identify and exploit apparent relationships in the training data that do not hold in general. The data is split into 8,144 training images and 8,041 testing images, where each class has been split roughly in a 50-50 split. The dataset is divided into two as negative and positive crack images for image classification. Image Classification on Small Datasets with Keras.
