机器学习定义：
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 measured by P, improves with experience E.在一个性能标准P下去完成任务T，得到经验E

监督学习：1.回归    设法预测连续值的属性

                   2.分类    设法预测离散值的输出（输出值>=2）

无监督学习：

                  聚类，都具有相同的标签，或者都无标签，分成一样的簇。
