The article explains that setting the mean to zero recenters data around the origin, making optimization algorithms converge faster, while scaling variance to one equalizes feature scales so no single feature dominates, illustrated with examples and visualizations of how standardization improves machine‑learning models.
This article explains how to detect and handle outliers in datasets using PHP and machine-learning techniques, covering the statistical Z-Score method and the Isolation Forest algorithm, and providing code examples for both removal and replacement of anomalous values to improve data quality and model accuracy.
