Belonging Network -- Few-shot One-class Image Classification for Classes with Various Distributions --
Takumi Ohkuma, Hideki Nakayama (UT) PRMU2020-44
Abstract (in Japanese) (See Japanese page) 
(in English) Few-shot one-class image classification is the task of recognizing a particular class while rejecting test images that do not belong to the class using only a few given training images. One promising strategy for this task is to employ meta learning to transfer knowledge from existing resources. In this paper, we propose a simple meta-learning based method “Belonging Network (BeNet)”. We use and compare some basic statistics of target classes to sketch their distributions and find that simple mean and variance information of the training image set contributes to improving the performance. Despite its surprising simplicity, BeNet achieves state-of-the-art performance in our experiments.
