- Abstract: Image classification has been studied extensively, but there has been limited
work in using unconventional, external guidance other than traditional
image-label pairs for training. We present a set of methods for leveraging
information about the semantic hierarchy embedded in class labels. We first
inject label-hierarchy knowledge into an arbitrary CNN-based classifier and
empirically show that availability of such external semantic information in
conjunction with the visual semantics from images boosts overall performance.
Taking a step further in this direction, we model more explicitly the
label-label and label-image interactions using order-preserving embeddings
governed by both Euclidean and hyperbolic geometries, prevalent in natural
language, and tailor them to hierarchical image classification and
representation learning. We empirically validate all the models on the
hierarchical ETHEC dataset.

Multi-label image classification (MLIC) is a fundamental and practical task, which aims to assign multiple possible labels to an image.
In recent years, many deep convolutional neural network (CNN) based approaches have been proposed which model label correlations.
This paper advances this research direction by improving the modeling of label correlations and the learning of semantic representations.
