Machine Learning
What is it
Undergraduate machine learning covers the core algorithms that let computers learn patterns from data rather than being explicitly programmed — including supervised learning (regression, classification), unsupervised learning (clustering), and the mathematics of training and evaluating models.
Why it matters
Machine learning underlies an enormous share of modern software — recommendation systems, fraud detection, medical diagnosis support, and search all rely on it — making a genuine understanding of how these algorithms work essential for a computer science education today.
Exam tip
Always evaluate a model on data it wasn't trained on, and understand what metric (accuracy, precision, recall, F1) actually matters for the specific problem — a model can have high accuracy while being nearly useless if the classes are imbalanced, and picking the wrong metric hides this.
