SecureCut: Federated Gradient Boosting Decision Trees with Efficient Machine Unlearning

no code implementations22 Nov 2023 Jian Zhang, Bowen Li Jie Li, Chentao Wu

In response to legislation mandating companies to honor the \textit{right to be forgotten} by erasing user data, it has become imperative to enable data removal in Vertical Federated Learning (VFL) where multiple parties provide private features for model training.

Temporal Gradient Inversion Attacks with Robust Optimization

no code implementations13 Jun 2023 Bowen Li, Hanlin Gu, Ruoxin Chen, Jie Li, Chentao Wu, Na Ruan, Xueming Si, Lixin Fan

We investigate a Temporal Gradient Inversion Attack with a Robust Optimization framework, called TGIAs-RO, which recovers private data without any prior knowledge by leveraging multiple temporal gradients.

Adaptive incentive for cross-silo federated learning: A multi-agent reinforcement learning approach

no code implementations15 Feb 2023 Shijing Yuan, Hongze Liu, Hongtao Lv, Zhanbo Feng, Jie Li, Hongyang Chen, Chentao Wu

To overcome these limitations, we propose a novel adaptive mechanism for cross-silo FL, towards incentivizing organizations to contribute data to maximize their long-term payoffs in a real dynamic training environment.
