FedSkillGit: Federated Skill Evolution via Version Control

FedSkillGit is a federated framework that enables large language model agents to evolve reusable natural‑language skills without sharing raw data. Instead of uploading entire skill documents, clients submit bounded patches and local experience summaries, which are filtered for privacy, deduplicated, and merged into a global skill candidate. The server distributes the candidate for client‑side validation, publishing it only when performance improves, and experiments show it outperforms baselines by up to 22% while approaching centralized results.

Vision Paper: Why Distributed LLM Post-Training and Decentralized Alignment Are Now Essential

The paper argues that distributed learning—federated and decentralized—should be a core approach for large language model post‑training, rather than an optional privacy measure. It critiques current methods like RLHF and DPO for assuming centralized preference data, citing scientific, practical, and ethical flaws. The authors present a three‑pillar framework (privacy and data sovereignty, pluralism and representational equity, robustness and scalability), formalize technical challenges such as reference drift and preference heterogeneity, and outline algorithmic directions and a research agenda to make distributed post‑training feasible.

Similarity-Aware Personalized Federated Learning in Heterogeneous Environments

The paper introduces SAPE-FL, a personalization framework for Federated Learning that anchors each client’s model to both a global model and a similarity-weighted peer-averaged model. By applying dynamic, client-specific regularization based on model and output similarity, SAPE-FL balances global knowledge transfer with peer collaboration, filtering out dissimilar clients. The authors provide theoretical convergence guarantees and demonstrate empirically that SAPE-FL outperforms state‑of‑the‑art methods in highly heterogeneous and low‑data scenarios.

Coordination on a Budget: Federated Active Learning with Few Labels

The paper introduces a federated active learning (FAL) approach that tackles data privacy and label scarcity by coordinating query selection across clients. In low-budget scenarios, it finds that homogeneous (IID) data actually requires stronger coordination to avoid redundant queries, while heterogeneous data naturally yields diversity—a reversal of the usual federated learning narrative. The authors propose a new framework that aligns client data in a shared embedding space via federated representation learning, enabling globally coordinated active selection while keeping annotations local, and demonstrate that this method outperforms existing FAL methods even with larger annotation budgets.
