A dual approach for federated learning

Zhenan Fan, Huang Fang, Michael P. Friedlander

We study the federated optimization problem from a dual perspective and propose a new algorithm termed federated dual coordinate descent (FedDCD), which is based on a type of coord…

Fair and efficient contribution valuation for vertical federated learning

Zhenan Fan, Huang Fang, Xinglu Wang +4

Federated learning is an emerging technology for training machine learning models across decentralized data sources without sharing data. Vertical federated learning, also known as…

Cardinality-constrained structured data-fitting problems

Zhenan Fan, Huang Fang, Michael P. Friedlander

A memory-efficient framework is described for the cardinality-constrained structured data-fitting problem. Dual-based atom-identification rules are proposed that reveal the structu…

Polar Deconvolution of Mixed Signals

Zhenan Fan, Halyun Jeong, Babhru Joshi +1

The signal demixing problem seeks to separate a superposition of multiple signals into its constituent components. This paper studies a two-stage approach that first decompresses a…

Polar Alignment and Atomic Decomposition

Zhenan Fan, Halyun Jeong, Yifan Sun +1

Structured optimization uses a prescribed set of atoms to assemble a solution that fits a model to data. Polarity, which extends the familiar notion of orthogonality from linear se…

Bundle methods for dual atomic pursuit

Zhenan Fan, Yifan Sun, Michael P. Friedlander

The aim of structured optimization is to assemble a solution, using a given set of (possibly uncountably infinite) atoms, to fit a model to data. A two-stage algorithm based on gau…
