Machine Learning
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 measued
计算机程序从经验E中学习，解决某一任务T进行某一性能度量P，通过P测定在T上的表现因经验E而提高
realy rhyme
Supervised Learning（监督学习）
right answers given
Regression problem
tring to predict continuios valued ouput
需要预测连续的数值输出
in that problem , you should give its some right valued with different classic and machine learning will learn to predict it
Classidication
discrete valued output (zero or one)
离散取值输出
in that problem, you should give some valued . Different with regression , maybe the type of data
Unspervised Learning
Clustering
maybe using clustring algorithm to break that data into two separate clusters
使用聚类算法将数据分为两簇
do not know what data mean and data features and so on(just about data information),and you know ,machine learning should classification those data into different clusters
the classic problem of that maybe Cocktail party problem algorithm
经典问题就是鸡尾酒派对算法，就是有背景音乐以及人声，能分理分离出两者的声音
