arXiv:2605.26327v1 Announce Type: new Abstract: Shampoo-based methods, such as KL-Shampoo and SOAP, have demonstrated strong performance in training neural networks and rely on QR decomposition. Because existing QR implementations require single-precision (FP32) arithmetic and remain computationally expensive, these methods become time- and memory-intensive when their preconditioning matrices are large. Moreover, using BFloat16 (BFP16) storage to reduce memory usage can degrade the performance of Shampoo-based methods. We propose a reparametrization of the preconditioner that supports BFP16 st
The continuous push for more efficient and scalable AI training, especially with larger models and memory-constrained hardware like BFloat16, necessitates innovations in optimization algorithms.
Improved preconditioning methods directly enhance the training efficiency and scalability of large neural networks, reducing computational costs and enabling more complex AI models.
Current limitations in computational cost and memory usage for advanced optimization algorithms in AI training are eased by this reparametrization, making them more practical for real-world applications.
