Geodesic‑SVDD introduces a distributed learning framework for structured tabular data that transforms each client’s task into a one‑class density estimation on a hypersphere, enabling aggregation of local models as probabilistic manifolds in a single communication round. The method employs a Residual Spherical Encoder and a Geodesic Latent Mixup to enforce strict hyperspherical constraints, preventing manifold collapse, and proposes a One‑Shot Product‑of‑Experts protocol for privacy‑preserving aggregation without iterative synchronization. Experiments on five tabular benchmarks and varying label skew levels show that Geodesic‑SVDD achieves the highest mean AUROC among seven federated methods, surpasses federated tree ensembles by up to 21 AUROC points, and its One‑Shot variant matches centralized Deep SVDD under IID and mild skew conditions.

FedCKA introduces a Centered Kernel Alignment (CKA)-based method for federated 3D perception that dynamically balances personalization and globalization. By computing layer-wise feature similarities between local client models and a global consensus model, FedCKA generates client‑specific aggregation masks to selectively share representation‑consistent layers. Experiments on a unified multi‑domain nuScenes benchmark demonstrate that FedCKA surpasses established federated baselines, improving average NDS by 7 percentage points.
Heterogeneous Differential Privacy (HDP) in Federated Learning (FL) allows clients to select individual privacy budgets ($\varepsilon_i$) according to institutional policies and data sensitivity. In practice, many HDP-FL systems employ $\varepsilon$-aware server aggregation to improve model utility by re-weighting client updates according to their declared privacy budgets.

The paper introduces FedGRC, a federated learning framework that enhances both global recognition and personalization for heterogeneous clients. It combines Consensus‑Guided Representation Learning, Multilayer Metric Synthesis, and Support‑Adaptive Shrinkage Personalization to address failures on rare or unseen classes. Experiments on CIFAR‑10, CIFAR‑100, and the FedRS dataset show that FedGRC outperforms 21 baseline methods, improving global accuracy and personalization floors by over 2% in several settings.

arXiv:2608. 15107v1 Announce Type: new Abstract: Federated learning (FL) is a practical framework that can train models on distributed user data while guaranteeing data privacy; however, due to heterogeneity in which each user has a different data distribution, problems frequently arise where both global and personalization performance deteriorate simultaneously.
arXiv:2605. 11165v3 Announce Type: replace Abstract: Federated learning (FL) in heterogeneous environments remains challenging because client models often differ in both architecture and data distribution.
