Entropy-Guided Tensor Compression for Multimodal Federated Learning on Edge Devices

arXiv:2607.06651v1 Announce Type: new Abstract: Federated learning (FL) over mobile and edge devices increasingly involves multimodal models in which clients differ in both sensing capability and computational capacity. Existing update compression schemes typically apply uniform policies across layers and devices, without accounting for modality-specific differences in spectral structure and compressibility. We propose MESH-FL, an entropy-guided matrix product state (MPS) update-compression framework for modality-heterogeneous FL on resource-constrained devices. MESH-FL estimates the spectral

Why this matters
Why now

The proliferation of diverse edge devices with varying capabilities is pushing the boundaries of traditional federated learning, demanding more efficient and adaptable compression techniques.

Why it’s important

This development addresses critical limitations in deploying advanced AI, particularly multimodal models, on resource-constrained edge devices, and is crucial for the decentralization and broader adoption of AI.

What changes

Federated learning can now be applied more effectively to heterogeneous edge environments, reducing communication overhead and computational demands for multimodal AI applications.
