In this work, we study robust deep learning against abnormal training data from the perspective of example weighting built in empirical loss functions, i. e., gradient magnitude with respect to logits, an angle that is not thoroughly studied so far.

To address this, we propose to build a set-based similarity structure by exploiting all instances in the gallery.

Therefore, we propose a novel sample mining method, called Online Soft Mining (OSM), which assigns one continuous score to each sample to make use of all samples in the mini-batch.

We show that with this additional reconstruction constraint, the learned projection function from the seen classes is able to generalise better to the new unseen classes.

Zero-shot learning (ZSL) can be considered as a special case of transfer learning where the source and target domains have different tasks/label spaces and the target domain is unlabelled, providing little guidance for the knowledge transfer.

The semantic manifold structure is used to redefine the distance metric in the semantic embedding space for more effective ZSL.
