FedRAHi: Reliability-Aware Hierarchical Collaboration for Federated Graph Foundation Models

FedRAHi, a Reliability-Aware Hierarchical collaboration framework for FedGFM that leverages the symbiotic knowledge to construct a client-aware affinity graph, and performs personalized weighting of client parameters based on the reliability scores is proposed.

Disagreement-Aware Subgraph Federated Learning via Uncertainty-Guided Local-Global Alignment

FedDUA is proposed, a novel disagreement-aware and uncertainty-guided framework for subgraph FL that first models cross-client semantic disagreement via a lightweight semantic anchor graph and derives adaptive aggregation weights for reliable global federated knowledge.

Federated Generalized Category Discovery via Personalized Contrastive Graph Learning

In this work, we investigate the task of Federated Generalized Category Discovery (Fed-GCD), which aims to leverage labeled data from known classes to cluster unlabeled samples from both known and unknown classes through privacy-preserving collaboration among clients. Existing Fed-GCD methods predominantly emphasize im...

Multi-View Clustering Goes Federated: A Survey

Overall, FedMVC represents a promising framework for privacy-preserving unsupervised learning in distributed environments and key research challenges include formal privacy–utility trade-offs, convergence under extreme data heterogeneity, and the integration of large language models for improved interpretability.

Task-Aware Federated Fine-Tuning for MoE-based Large Language Models

FedTAR is proposed, a task-aware federated fine-tuning method for MoE-based LLMs that establishes the association between local updates and task preference via routing outputs and preserves expert specialization and mitigates destructive interference among heterogeneous clients.

Personalized and Multi-View Representation for Federated Cold-Start Recommendation

PMFRec learns a personalized representation generator to produce user-specific item representations from attribute features, and introduces a global multi-view encoder with item-adaptive gating and an orthogonality objective to capture complementary semantic views while reducing cross-view redundancy.
