Layer-Wise Adaptive Model Aggregation for Scalable Federated Learning

AAAI 2023technical

In Federated Learning (FL), a common approach for aggregating local solutions across clients is periodic full model averaging. It is, however, known that different layers of neural networks can have a different degree of model discrepancy across the clients. The conventional full aggregation scheme…

Securing Secure Aggregation: Mitigating Multi-Round Privacy Leakage in Federated Learning

AAAI 2023technical

Secure aggregation is a critical component in federated learning (FL), which enables the server to learn the aggregate model of the users without observing their local models. Conventionally, secure aggregation algorithms focus only on ensuring the privacy of individual users in a single training ro…

ApproxIFER: A Model-Agnostic Approach to Resilient and Robust Prediction Serving Systems

AAAI 2022technical

Due to the surge of cloud-assisted AI services, the problem of designing resilient prediction serving systems that can effectively cope with stragglers and minimize response delays has attracted much interest. The common approach for tackling this problem is replication which assigns the same predic…
