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
