机器学习之监督学习

监督学习(supervised-learning)

regression(回归)

Given a picture of a person, we have to predict their age on the basis of the given picture

通过历史的数据,预测新的数据(线性)

eg:预测问题、房价问题

classification(分类)

Given a patient with a tumor, we have to predict whether the tumor is malignant or benign.

根据特征识别,无数个好特征(向量),然后判断属于哪个

eg:识别问题、肿瘤问题

无监督学习(unsupervised-learning)

通过聚类(分组)算法,无需指定特征

聚类(Clustering)

eg: 新闻分组

集群(Non-clustering)

eg:音频分离
