Classical Machine Learning Models
Classical machine learning models refer to traditional statistical and algorithmic approaches for pattern recognition and prediction, developed before the deep learning era. These include supervised models like linear regression and decision trees, unsupervised models like k-means clustering, and ensemble methods like random forests. They are widely used for structured data analysis, classification, regression, and clustering tasks in various domains.
Developers should learn classical ML models for interpretable, efficient solutions on small to medium-sized datasets, especially when computational resources are limited or transparency is critical. They are essential in industries like finance for credit scoring, healthcare for disease prediction, and marketing for customer segmentation, where model explainability and performance on tabular data are prioritized over raw predictive power.
