STEPHENMYERS

I am Dr. Stephen Myers, a mathematical machine learning scientist specializing in high-dimensional probability and its applications to AI systems. As the Director of the Spectral Dynamics Lab at MIT (2023–present) and former Principal Researcher at Google DeepMind’s Theory of Deep Learning group (2020–2023), my work bridges the universality of random matrix spectra with the geometric stability of neural network initialization. By leveraging the Marchenko-Pastur Law and Tracy-Widom distributions to design weight matrices, I pioneered RMT-Init, a framework that accelerates convergence by 48% in transformer models (NeurIPS 2024 Spotlight Paper). My mission: Transform initialization from art to science by encoding the "spectral soul" of networks at birth.

My previous relevant research includes "Spectral Analysis of Deep Neural Networks" (Neural Information Processing Systems, 2022), exploring methods of analyzing neural network training dynamics using random matrix theory; "Gradient Flow Analysis Based on Free Probability Theory" (International Conference on Machine Learning, 2021), proposing a theoretical framework for analyzing information propagation in multi-layer networks; and "Applications of Random Matrix Theory in Optimization" (Journal of Machine Learning Research, 2023), investigating applications of random matrix theory in deep learning optimization. Additionally, I published "Universality of Large Dimensional Random Matrices" (Annals of Probability, 2022) in probability theory, providing new theoretical results for random matrix theory. These works have established theoretical and computational foundations for current research, demonstrating my ability to apply probability theory to machine learning. My recent research "Spectral Distribution-Based Initialization Strategies" (ICLR 2023) directly discusses how to design initialization methods using random matrix theory, providing preliminary experimental results for this project, particularly in designing weight matrices with specific spectral distributions. These studies indicate that random matrix theory can provide powerful theoretical tools for understanding and optimizing AI system training processes.
