Federated learning: Strategies for improving communication efficiency

J Konečný, HB McMahan, FX Yu, P Richtárik… - arXiv preprint arXiv …, 2016 - arxiv.org
Federated Learning is a machine learning setting where the goal is to train a high-quality
centralized model while training data remains distributed over a large number of clients each …

Simplified models for LHC new physics searches

…, J Wacker, W Waltenberger, I Yavin, F Yu… - Journal of Physics G …, 2012 - iopscience.iop.org
This document proposes a collection of simplified models relevant to the design of new-physics
searches at the Large Hadron Collider (LHC) and the characterization of their results. …

A field guide to federated optimization

…, H Wang, B Woodworth, S Wu, FX Yu… - arXiv preprint arXiv …, 2021 - arxiv.org
Federated learning and analytics are a distributed approach for collaboratively learning
models (or statistics) from decentralized data, motivated by and designed for privacy protection. …

cpSGD: Communication-efficient and differentially-private distributed SGD

N Agarwal, AT Suresh, FXX Yu… - Advances in Neural …, 2018 - proceedings.neurips.cc
Distributed stochastic gradient descent is an important subroutine in distributed learning. A
setting of particular interest is when the clients are mobile devices, where two important …

Long-lived particles at the energy frontier: the MATHUSLA physics case

…, B Tweedie, SM West, C Young, F Yu… - Reports on progress …, 2019 - iopscience.iop.org
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a
comprehensive survey of standard model (SM) extensions. LLPs are a common prediction of …

An exploration of parameter redundancy in deep networks with circulant projections

Y Cheng, FX Yu, RS Feris, S Kumar… - Proceedings of the …, 2015 - openaccess.thecvf.com
We explore the redundancy of parameters in deep neural networks by replacing the
conventional linear projection in fully-connected layers with the circulant projection. The circulant …

Pre-training tasks for embedding-based large-scale retrieval

WC Chang, FX Yu, YW Chang, Y Yang… - arXiv preprint arXiv …, 2020 - arxiv.org
We consider the large-scale query-document retrieval problem: given a query (eg, a question),
return the set of relevant documents (eg, paragraphs containing the answer) from a large …

Self-supervised learning for large-scale item recommendations

T Yao, X Yi, DZ Cheng, F Yu, T Chen, A Menon… - Proceedings of the 30th …, 2021 - dl.acm.org
Large scale recommender models find most relevant items from huge catalogs, and they
play a critical role in modern search and recommendation systems. To model the input space …
