Machine learning (ML) is the field of computer science focused on building systems that learn patterns from data rather than following explicitly programmed rules. It encompasses a broad spectrum from classical statistical methods (linear regression, decision trees, clustering, random forests) through deep learning (neural networks with many layers) to the modern generative AI and foundation models that dominate current attention. ML is the parent field within which generative AI is a recent and currently dominant subcategory. Most ML work today is still classical or traditional deep learning; generative AI is the most visible but not the totality of ML.
