AdaTriplet-RA: Domain Matching via Adaptive Triplet and Reinforced Attention for Unsupervised Domain Adaptation

1 code implementation16 Nov 2022 Xinyao Shu, ShiYang Yan, Zhenyu Lu, Xinshao Wang, Yuan Xie

Unsupervised domain adaption (UDA) is a transfer learning task where the data and annotations of the source domain are available but only have access to the unlabeled target data during training.

ROBUST DISCRIMINATIVE REPRESENTATION LEARNING VIA GRADIENT RESCALING: AN EMPHASIS REGULARISATION PERSPECTIVE

no code implementations25 Sep 2019 Xinshao Wang, Yang Hua, Elyor Kodirov, Neil M. Robertson

It is fundamental and challenging to train robust and accurate Deep Neural Networks (DNNs) when semantically abnormal examples exist.

IMAE for Noise-Robust Learning: Mean Absolute Error Does Not Treat Examples Equally and Gradient Magnitude's Variance Matters

3 code implementations28 Mar 2019 Xinshao Wang, Yang Hua, Elyor Kodirov, Neil M. Robertson

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.

Ranked List Loss for Deep Metric Learning

2 code implementations CVPR 2019 Xinshao Wang, Yang Hua, Elyor Kodirov, Neil M. Robertson

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

Deep Metric Learning by Online Soft Mining and Class-Aware Attention

3 code implementations4 Nov 2018 Xinshao Wang, Yang Hua, Elyor Kodirov, Guosheng Hu, Neil M. Robertson

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.
