Machine Learning

    —grew out of work in AI

   —new capability for computers

 

Examples:

    --Database mining

          large datasets from growth of automation/web.

          E.g, Web click data, medical records, biology, enginerring

   --Application can't program by hand.

          E.g, autonomous helicopter, handwriting recognization,

          Natural Language Processing(NLP),Computer vision.

   --Self-customizing programs

          E.g, Amazon, Netflix product recommendations

   --Understanding human learning(brain,real AI).

 

What is Machine Learning

       Arthur Samul(1959):Fileds of study that gives computers the ability to learn without being explicitly programmed.--机器在某领域中的自动学习能力

       Tom Mitchell(1998):A computer program is said to learn from experience E with respect to some task T and some performace measure P,if its performace on T,as measured P,improves with experience E.--对于一个任务T,具有经验E,如果此时有P动作执行在T上,那么根据P的执行结果,可以提高经验E。即根据对任务T不同的动作P累积经验E。

 

       两种算法:

       --supervised learning(被动学习)

          为程序给出了正确的经验,即根据先验的样本,计算出解析方式,程序根据解析方式给出结果并提高概率。

          有两种类型:regression problem--回归问题,得出一个数值

                           classification problem--分类问题,答案是离散的值

       --unsupervised learning(主动学习)

          程序根据样本的特征进行分析,并自发计算出分类方式

 

       --两者的区别:前者给出分类,根据分类结果对新数据进行分类学习,给出答案

                           后者是根据数据的特征对其进行分类;
