The Fine Line between Aid and Interference: Insights from Informatics on Healthcare AI

Artificial Intelligence (AI) is increasingly being integrated into healthcare, promising enhanced efficiency and improved patient care. Employed more as a supplement rather than a substitute to human decision-making, AI in healthcare serves multiple functions ranging from alerts integrated in electronic medical records (EMRs), to advanced large language models (LLMs) capable of making highly accurate clinical…

Matrices of Quantized Eigenvectors for Second-Order Optimization of 4-bit Deep Learning Networks

Deep neural networks (DNNs) have found widespread success across various fields. This success can be attributed to first-order optimizers such as stochastic gradient descent with momentum (SGDM) and AdamW. However, these methods encounter challenges in efficiently training large-scale models. As an alternative, second-order optimizers like K-FAC, Shampoo, AdaBK, and Sophia have demonstrated superior convergence properties,…
