目前实现的 LinearSVM 虽说能用,但其实存在着内存方面的隐患。为了解决这个隐患,一个常见的做法是分 Batch 训练,这将会导致“更新参数”步骤每次接受的数据都是“不固定”的数据——原数据的一个小 Batch。为了描述这个“不固定”的数据、我们就需要利用到 Tensorflow 中的“占位符(Placeholder)”,其用法非常直观:...

顾名思义。分类算法用于离散型分布预測,如前面讲过的KNN、决策树、朴素贝叶斯、adaboost、SVM、Logistic回归都是分类算法。回归算法用于连续型分布预測。针对的是数值型的样本,使用回归。能够在给定输入的时候预測出一个数值。这是对分类方法的提升,由于这样能够预測连续型数据而不不过离散的类别标签。
