- Supervised — labeled data; regression (continuous output) or classification (categorical output)
- Unsupervised — unlabeled data; clustering and dimensionality reduction
- Semi-supervised — a small amount of labeled data plus a large amount of unlabeled data
- Reinforcement learning — an agent takes actions in an environment to maximize cumulative reward
Types of Machine Learning
The four broad categories of machine learning, based on what kind of data and feedback the model learns from.
