Machine Learning Optimization & Modeling

New simulation results offer guidance for practitioners deciding between regularization techniques, analyzing 134,400 model runs to determine when to favor Ridge, Lasso, or Elastic Net based on pre-fitting metrics. Separately, a comparison of quantization algorithms revealed that a technique developed in 2021 maintains superior accuracy over a purported 2026 successor, showing that accuracy hinges critically on the choice of a single scale parameter in rotation-based vector quantization.
