Abstract: We propose a novel setting for learning, where the input domain is the image of a map defined on the product of two sets, one of which completely determines the labels. Given the ability to sample from each set independently, we present an algorithm that learns a classifier over the input domain more efficiently than sampling from the input domain directly. We apply this setting to visual classification tasks, where our approach enables us to train classifiers on datasets that consist entirely of a single example of each class. On several standard benchmarks for real-world image classification, our approach achieves performance competitive with state-of-the-art results from the few-shot learning and domain transfer literature, while using significantly less data.
