Gradient based Feature Attribution in Explainable AI: A Technical Review

no code implementations15 Mar 2024 Yongjie Wang, Tong Zhang, Xu Guo, Zhiqi Shen

Due to the lack of a rigorous definition of explainable AI (XAI), a plethora of research related to explainability, interpretability, and transparency has been developed to explain and analyze the model from various perspectives.

Explaining Language Models' Predictions with High-Impact Concepts

no code implementations3 May 2023 Ruochen Zhao, Shafiq Joty, Yongjie Wang, Tan Wang

The emergence of large-scale pretrained language models has posed unprecedented challenges in deriving explanations of why the model has made some predictions.

DualCF: Efficient Model Extraction Attack from Counterfactual Explanations

no code implementations13 May 2022 Yongjie Wang, Hangwei Qian, Chunyan Miao

We then propose DualCF strategy to circumvent the above issues, which is achieved by taking not only CF but also counterfactual explanation of CF (CCF) as pairs of training samples for the substitute model.

Hedging longevity risk in defined contribution pension schemes

no code implementations23 Apr 2019 Ankush Agarwal, Christian-Oliver Ewald, Yongjie Wang

We transform this constrained optimal investment problem into an unconstrained problem by replicating a self-financing portfolio of future contributions from the member and the minimum guarantee provided by the scheme.

Removing Stripes, Scratches, and Curtaining with Non-Recoverable Compressed Sensing

no code implementations23 Jan 2019 Jonathan Schwartz, Yi Jiang, Yongjie Wang, Anthony Aiello, Pallab Bhattacharya, Hui Yuan, Zetian Mi, Nabil Bassim, Robert Hovden

Highly-directional image artifacts such as ion mill curtaining, mechanical scratches, or image striping from beam instability degrade the interpretability of micrographs.
