“Supervised learning is the machine learning task of inferring a function from labeled training data.The training data consist of a set of training examples.”
- Regression
- Classification ……
“Unsupervised learning is the machine learning task of inferring a function to describe hidden structure from unlabeled data."
- Clustering
- …
