A Stochastic Quasi-Newton Method for Non-convex Optimization with Non-uniform Smoothness

no code implementations22 Mar 2024 Zhenyu Sun, Ermin Wei

Leveraging gradient clipping and variance reduction, our algorithm can achieve the best-known $\mathcal{O}(\epsilon^{-3})$ sample complexity and enjoys convergence speedup with simple hyperparameter tuning.

Understanding Generalization of Federated Learning via Stability: Heterogeneity Matters

no code implementations6 Jun 2023 Zhenyu Sun, Xiaochun Niu, Ermin Wei

While the existing literature has studied extensively the generalization performances of centralized machine learning algorithms, similar analysis in the federated settings is either absent or with very restrictive assumptions on the loss functions.

Collaborative Multi-Agent Video Fast-Forwarding

no code implementations27 May 2023 Shuyue Lan, Zhilu Wang, Ermin Wei, Amit K. Roy-Chowdhury, Qi Zhu

We show that compared with other approaches in the literature, our frameworks achieve better coverage of important frames, while significantly reducing the number of frames processed at each agent.

A Communication-efficient Algorithm with Linear Convergence for Federated Minimax Learning

no code implementations2 Jun 2022 Zhenyu Sun, Ermin Wei

Most existing federated minimax algorithms either require communication per iteration or lack performance guarantees with the exception of Local Stochastic Gradient Descent Ascent (SGDA), a multiple-local-update descent ascent algorithm which guarantees convergence under a diminishing stepsize.

Faithful Edge Federated Learning: Scalability and Privacy

no code implementations30 Jun 2021 Meng Zhang, Ermin Wei, Randall Berry

To this end, we formulate the first faithful implementation problem of federated learning and design two faithful federated learning mechanisms which satisfy economic properties, scalability, and privacy.

Federated Learning

Distributed Multi-agent Video Fast-forwarding

1 code implementation10 Aug 2020 Shuyue Lan, Zhilu Wang, Amit K. Roy-Chowdhury, Ermin Wei, Qi Zhu

In many intelligent systems, a network of agents collaboratively perceives the environment for better and more efficient situation awareness.
