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.

Cross-Silo Federated Learning for Multi-Tier Networks with Vertical and Horizontal Data Partitioning

no code implementations19 Aug 2021 Anirban Das, Timothy Castiglia, Shiqiang Wang, Stacy Patterson

Each silo contains a hub and a set of clients, with the silo's vertical data shard partitioned horizontally across its clients.

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.
