Linear Context Transform Block

no code implementations6 Sep 2019 Dongsheng Ruan, Jun Wen, Nenggan Zheng, Min Zheng

In this work, we first revisit the SE block, and then present a detailed empirical study of the relationship between global context and attention distribution, based on which we propose a simple yet effective module, called Linear Context Transform (LCT) block.

Bayesian Uncertainty Matching for Unsupervised Domain Adaptation

no code implementations24 Jun 2019 Jun Wen, Nenggan Zheng, Junsong Yuan, Zhefeng Gong, Changyou Chen

By imposing distribution matching on both features and labels (via uncertainty), label distribution mismatching in source and target data is effectively alleviated, encouraging the classifier to produce consistent predictions across domains.
