Diagnosing Concept Drift with Visual Analytics

no code implementations28 Jul 2020 Weikai Yang, Zhen Li, Mengchen Liu, Yafeng Lu, Kelei Cao, Ross Maciejewski, Shixia Liu

Concept drift is a phenomenon in which the distribution of a data stream changes over time in unforeseen ways, causing prediction models built on historical data to become inaccurate.

Analyzing the Noise Robustness of Deep Neural Networks

no code implementations26 Jan 2020 Kelei Cao, Mengchen Liu, Hang Su, Jing Wu, Jun Zhu, Shixia Liu

The key is to compare and analyze the datapaths of both the adversarial and normal examples.

Adversarial Attack

Analyzing the Noise Robustness of Deep Neural Networks

no code implementations9 Oct 2018 Mengchen Liu, Shixia Liu, Hang Su, Kelei Cao, Jun Zhu

Deep neural networks (DNNs) are vulnerable to maliciously generated adversarial examples.

Cross Domain Knowledge Transfer for Person Re-identification

no code implementations18 Nov 2016 Qiqi Xiao, Kelei Cao, Haonan Chen, Fangyue Peng, Chi Zhang

Building on the idea that identity classification, attribute recognition and re- identification share the same mid-level semantic representations, they can be trained sequentially by fine-tuning one based on another.
