Communication-Efficient Distributed Training for Collaborative Flat Optima Recovery in Deep Learning
arXiv:2507.20424v3 Announce Type: replace Abstract: We study centralized distributed data parallel training of deep neural networks (DNNs), aiming to improve the trade-off between communication efficiency and model performance of the local gradient methods. To this end, we revisit the flat-minima hypothesis, which suggests that models with better generalization tend to lie in flatter regions of the loss landscape. We introduce a simple, yet effective, sharpness measure, Inverse Mean Valley, and demonstrate its strong correlation with the generalization gap of DNNs. We incorporate an efficient
The continuous drive for more efficient and scalable deep learning training methods, coupled with the increasing computational demands of larger models, makes advancements in communication efficiency critical.
Improving communication efficiency is vital for scaling distributed AI training, directly impacting the cost, speed, and environmental footprint of developing advanced AI models for both public and private sectors.
Distributed deep learning training can become significantly faster and more resource-efficient, potentially accelerating research and development cycles for large-scale AI applications.
