We consider the problem of data augmentation, i.e., generating artificial
samples to extend a given corpus of training data. Specifically, we propose
attributed-guided augmentation (AGA) which learns a mapping that allows to
synthesize data such that an attribute of a synthesized sample is at a desired
value or strength. This is particularly interesting in situations where little
data with no attribute annotation is available for learning, but we have access
to a large external corpus of heavily annotated samples. While prior works
primarily augment in the space of images, we propose to perform augmentation in
feature space instead. We implement our approach as a deep encoder-decoder
architecture that learns the synthesis function in an end-to-end manner. We
demonstrate the utility of our approach on the problems of (1) one-shot object
recognition in a transfer-learning setting where we have no prior knowledge of
the new classes, as well as (2) object-based one-shot scene recognition. As
external data, we leverage 3D depth and pose information from the SUN RGB-D
dataset. Our experiments show that attribute-guided augmentation of high-level
CNN features considerably improves one-shot recognition performance on both
problems.
