Fine-grained Anomaly Detection in Sequential Data via Counterfactual Explanations

no code implementations9 Oct 2022 He Cheng, Depeng Xu, Shuhan Yuan, Xintao Wu

Given a sequence that is detected as anomalous, we can consider anomalous entry detection as an interpretable machine learning task because identifying anomalous entries in the sequence is to provide an interpretation to the detection result.

Fairness-aware Agnostic Federated Learning

no code implementations10 Oct 2020 Wei Du, Depeng Xu, Xintao Wu, Hanghang Tong

In this paper, we develop a fairness-aware agnostic federated learning framework (AgnosticFair) to deal with the challenge of unknown testing distribution.

Removing Disparate Impact of Differentially Private Stochastic Gradient Descent on Model Accuracy

no code implementations8 Mar 2020 Depeng Xu, Wei Du, Xintao Wu

In this work, we analyze the inequality in utility loss by differential privacy and propose a modified differentially private stochastic gradient descent (DPSGD), called DPSGD-F, to remove the potential disparate impact of differential privacy on the protected group.

Achieving Differential Privacy in Vertically Partitioned Multiparty Learning

no code implementations11 Nov 2019 Depeng Xu, Shuhan Yuan, Xintao Wu

Evaluation on real-world and synthetic datasets for linear and logistic regressions shows the effectiveness of our proposed method.
