Quantized Eigenvector Matrices for 4-bit Second-Order Optimization of Deep Neural Networks

Title: Memory-Efficient AI Solutions for Deep Neural Networks Deep neural networks (DNNs) have achieved great success in various fields, but face challenges in training large-scale models efficiently due to memory and computational costs. Researchers have developed a 4-bit second-order optimizer, named Shampoo, which significantly reduces memory consumption while maintaining performance comparable to its 32-bit counterpart. This is achieved by quantizing the eigenvector matrix of the preconditioner, preserving small singular values crucial for accurate computation. The practical value of this research is evident in the significant memory savings it offers, enabling the widespread use of memory-efficient second-order optimizers in training large-scale DNNs.
