Machine Learning Notes 01

Mordern Defination:

  “A computer program is said to learn from experience E with respect to some task T and some performance measure P if its performance on T, as measured by P, improves with experience E.”

​ ——Tom Mitchell(1998)

Types of problems and tasks:

“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
• …

Besides, there are also Semi-supervised Learnings and Reinforcement learning.
