**TLDR:** A regression method that builds target-aware latent components, especially in highly correlated and high-dimensional feature spaces.

<p>Partial Least Squares Regression considers both the relationships among predictors and their connection to the target variable. This distinguishes it from dimensionality reduction approaches that only maximize variance. It is especially powerful in fields such as chemometrics, bioinformatics, and highly correlated sensor data. By combining dimension reduction and prediction in one framework, it becomes particularly valuable for advanced regression problems.</p>
