4 Major machine learning techniques

(1)tegression/Estimation

  • Predicting continuous values

(2)Classification\

  • Predicting the item class/category of a case

(3)Clustering

  • Finding the structure of data;summarization

(4)Associations

  • Associaing frequent co-occurring items /events.比如纸尿裤和啤酒的关系

(5)Anomaly detection

  • Discovering abnormal and unusual cases

(6)Sequence mining

  • Predicting next events ;click-stream(Markov Model,HMM)

(7)Dimension Reduction

  • Reducing the size of data(PCA)

(8)Recommendation systems

  • Recommending items和人喜好相关

5 Difference between artificial intelligence ,Machine learing ,and deep learning

(1)AI components

  • Computer Vision
  • Language Processing
  • Creativity
  • Etc.

(2)Machine learning
是AI的一个分支,包含人工智能的统计。通过学习大数据去做一个新Solution中的相似的problem。

  • Classification
  • Clustering
  • Etc.

(3)Revolution in ML
学习并且自己做出智能的决定

  • Deep learning

总之,相比较于机器学习算法,深度学习包含了自动化更深的层次水平。

5 Let’s get started with machine learning

(1)Machine learning application
(2)Machine learning algorithms

  • 有监督、无监督学习
  • 模型评估和各种机器学习算法
