Understanding the Stability-based Generalization of Personalized Federated Learning

ICLR 2025poster

Despite great achievements in algorithm design for Personalized Federated Learning (PFL), research on the theoretical analysis of generalization is still in its early stages. Some theoretical results have investigated the generalization performance of personalized models under the problem setting an…

Decentralized Directed Collaboration for Personalized Federated Learning

CVPR 2024poster

Personalized Federated Learning (PFL) is proposed to find the greatest personalized models for each client. To avoid the central failure and communication bottleneck in the server-based FL we concentrate on the Decentralized Personalized Federated Learning (DPFL) that performs distributed model trai…

Improving the Model Consistency of Decentralized Federated Learning

ICML 2023poster

To mitigate the privacy leakages and communication burdens of Federated Learning (FL), decentralized FL (DFL) discards the central server and each client only communicates with its neighbors in a decentralized communication network. However, existing DFL suffers from high inconsistency among local c…

Make Landscape Flatter in Differentially Private Federated Learning

CVPR 2023poster

To defend the inference attacks and mitigate the sensitive information leakages in Federated Learning (FL), client-level Differentially Private FL (DPFL) is the de-facto standard for privacy protection by clipping local updates and adding random noise. However, existing DPFL methods tend to make a s…

Deep Rank Cross-Modal Hashing with Semantic Consistent for Image-Text Retrieval

ICASSP 2022accepted

Cross-modal hashing retrieval approaches maps heterogeneous multi-modal data into a common hamming space to achieve efficient and flexible retrieval performance. However, existing cross-modal methods mainly exploit feature-level similarity between multi-modal data, the label-level similarity and rel…
