A Survey of Privacy Threats and Defense in Vertical Federated Learning: From Model Life Cycle Perspective

no code implementations6 Feb 2024 Lei Yu, Meng Han, Yiming Li, Changting Lin, Yao Zhang, Mingyang Zhang, Yan Liu, Haiqin Weng, Yuseok Jeon, Ka-Ho Chow, Stacy Patterson

Vertical Federated Learning (VFL) is a federated learning paradigm where multiple participants, who share the same set of samples but hold different features, jointly train machine learning models.

LESS-VFL: Communication-Efficient Feature Selection for Vertical Federated Learning

no code implementations3 May 2023 Timothy Castiglia, Yi Zhou, Shiqiang Wang, Swanand Kadhe, Nathalie Baracaldo, Stacy Patterson

As part of the training, the parties wish to remove unimportant features in the system to improve generalization, efficiency, and explainability.

A Sample-Based Algorithm for Approximately Testing $r$-Robustness of a Digraph

no code implementations25 Jul 2022 Yuhao Yi, YuAn Wang, Xingkang He, Stacy Patterson, Karl H. Johansson

In this paper, we propose a sample-based algorithm to approximately test $r$-robustness of a digraph with $n$ vertices and $m$ edges.

Compressed-VFL: Communication-Efficient Learning with Vertically Partitioned Data

no code implementations16 Jun 2022 Timothy Castiglia, Anirban Das, Shiqiang Wang, Stacy Patterson

Our work provides the first theoretical analysis of the effect message compression has on distributed training over vertically partitioned data.

Multi-Level Local SGD: Distributed SGD for Heterogeneous Hierarchical Networks

no code implementations ICLR 2021 Timothy Castiglia, Anirban Das, Stacy Patterson

We propose Multi-Level Local SGD, a distributed stochastic gradient method for learning a smooth, non-convex objective in a multi-level communication network with heterogeneous workers.

Multi-Level Local SGD for Heterogeneous Hierarchical Networks

1 code implementation27 Jul 2020 Timothy Castiglia, Anirban Das, Stacy Patterson

In our algorithm, sub-networks execute a distributed SGD algorithm, using a hub-and-spoke paradigm, and the hubs periodically average their models with neighboring hubs.

EdgeBench: Benchmarking Edge Computing Platforms

1 code implementation14 Nov 2018 Anirban Das, Stacy Patterson, Mike P. Wittie

The emerging trend of edge computing has led several cloud providers to release their own platforms for performing computation at the 'edge' of the network.
