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
