Machine Learning Foundations & Optimization

New empirical work provides a decision framework for practitioners selecting between Ridge, Lasso, and Elastic Net regularizers, derived from analyzing 134,400 distinct simulations and based on three computable pre-fitting metrics. Concurrently, research on model compression reveals that an older 2021 quantization algorithm surprisingly maintains superior accuracy over a newer 2026 successor, with performance hinging entirely on a single scale parameter within rotation-based vector quantization schemes.
