Improving Trainability of Variational Quantum Circuits via Regularization Strategies

no code implementations2 May 2024 Jun Zhuang, Jack Cunningham, Chaowen Guan

In the era of noisy intermediate-scale quantum (NISQ), variational quantum circuits (VQCs) have been widely applied in various domains, advancing the superiority of quantum circuits against classic models.

Debiasing Machine Unlearning with Counterfactual Examples

no code implementations24 Apr 2024 Ziheng Chen, Jia Wang, Jun Zhuang, Abbavaram Gowtham Reddy, Fabrizio Silvestri, Jin Huang, Kaushiki Nag, Kun Kuang, Xin Ning, Gabriele Tolomei

This bias emerges from two main sources: (1) data-level bias, characterized by uneven data removal, and (2) algorithm-level bias, which leads to the contamination of the remaining dataset, thereby degrading model accuracy.

Deperturbation of Online Social Networks via Bayesian Label Transition

1 code implementation27 Oct 2020 Jun Zhuang, Mohammad Al Hasan

However, a small number of users, so-called perturbators, may perform random activities on an OSN, which significantly deteriorate the performance of a GCN-based node classification task.
