Machine Learning: Core Ideas and Data Splits

Build an intuitive foundation in machine learning tasks, model concepts, and responsible data splits.

Looking for step-by-step tutorials for individual AI tools?

Course overview

A four-lesson entry path from the basic idea of machine learning to learning-task categories, model concepts, and data splitting. Learners compare supervised, unsupervised, and reinforcement-learning examples, then examine why training and evaluation data must be separated carefully. The final activity applies these ideas to a small, permissioned dataset; no programming background is required.

Describe machine learning as finding patterns in examples and distinguish it from a fixed hand-written rule. Classify simple scenarios as supervised, unsupervised, or reinforcement learning and explain what evidence each uses. Identify features, a target, training data, and evaluation data in a basic prediction task. Propose a data split that reduces leakage and explain one limitation of the resulting evaluation.

No programming or statistics experience is required. Familiarity with rows and columns is helpful; use only public or otherwise permitted practice data.
