什么是机器学习
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.
机器学习主要分为监督学习(supervised learning)、无监督学习(unsupervised learning)、其他(强化学习、推荐系统)
监督学习
监督学习:给出正确标签
若欲预测的是离散值,为分类Classification。若欲预测的是连续值,为回归Regression。
无监督学习
无监督学习:从没有标记的数据集中,找出数据中的结构。eg:聚类
