introduction

machine learning:

Field of study that gives computers the ability to learn without being explicitly programmed

Supervised learning

• "Right answer" given
• regression: 设法预测连续值
• Classifiation 预测离散值的输出值
• How to deal with infinite number of features?——Support vector machine

Unsupervised learning

• Without "right answer"
• Find the structure of data in a given data set.
• Clustering algorithm
