Repairing Group-Level Errors for DNNs Using Weighted Regularization

1 code implementation24 Mar 2022 Ziyuan Zhong, Yuchi Tian, Conor J. Sweeney, Vicente Ordonez, Baishakhi Ray

In particular, it can repair confusion error and bias error of DNN models for both single-label and multi-label image classifications.

Understanding Local Robustness of Deep Neural Networks under Natural Variations

1 code implementation9 Oct 2020 Ziyuan Zhong, Yuchi Tian, Baishakhi Ray

To this end, we study the local per-input robustness properties of the DNNs and leverage those properties to build a white-box (DeepRobust-W) and a black-box (DeepRobust-B) tool to automatically identify the non-robust points.

Testing DNN Image Classifiers for Confusion & Bias Errors

1 code implementation20 May 2019 Yuchi Tian, Ziyuan Zhong, Vicente Ordonez, Gail Kaiser, Baishakhi Ray

We found that many of the reported erroneous cases in popular DNN image classifiers occur because the trained models confuse one class with another or show biases towards some classes over others.

DeepTest: Automated Testing of Deep-Neural-Network-driven Autonomous Cars

1 code implementation28 Aug 2017 Yuchi Tian, Kexin Pei, Suman Jana, Baishakhi Ray

Most existing testing techniques for DNN-driven vehicles are heavily dependent on the manual collection of test data under different driving conditions which become prohibitively expensive as the number of test conditions increases.
