FDRMFL: Multimodal Federated Feature Extraction Model Based on Information Maximization and Contrastive Learning
arXiv:2512.02076v2 Announce Type: replace Abstract: We propose FDRMFL, a task-driven multimodal feature extraction framework for federated regression under non-IID data distributions. Extracting predictive features from high-dimensional multimodal inputs is particularly challenging in this setting: data cannot leave each client, local samples are scarce and heterogeneously distributed, and unsupervised dimensionality reduction discards task-relevant information while federated training introduces representation drift across communication rounds. FDRMFL addresses these challenges through a unif
The increasing need for privacy-preserving AI and the proliferation of distributed data sources are driving advancements in federated learning techniques.
This development addresses critical challenges in federated learning, enabling more effective AI model training with sensitive, heterogeneous, and siloed data, which is crucial for real-world applications.
The ability to extract predictive features from high-dimensional, multimodal, and non-IID federated data without centralizing it significantly improves the practical viability and performance of distributed AI systems.
