Machine Learning Optimization & Evaluation

A practitioner's guide analyzing regularization techniques reveals a decision framework for selecting between Ridge, Lasso, and Elastic Net based on three computable pre-fitting quantities derived from 134,400 simulations. Separately, research into vector quantization demonstrated that a 2021 algorithm outperforms its 2026 successor when accuracy hinges on the precise tuning of a single scale parameter for rotation-based methods.
