通俗解释优化的线性感知机算法：Pocket PLA

在上一篇文章：【附源码】一看就懂的感知机算法PLA我们详细介绍了线性感知机算法模型，并使用pyhon实例，验证了PLA的实际分类效果。下图是PLA实际的分类效果：但是，文章最后我们提出了一个疑问，就是PLA只能解决线性可分的问题。对于数据本身不是线性可分的情况，又该如何解决呢？下面，我们就将对PLA进行优化，以解决更一般的线性不可分问题。1 Pocket PLA是什么首先，我们来看一....

什么是感知机「Perceptron」PLA全称是Perceptron Linear Algorithm，即线性感知机算法，属于一种最简单的感知机（Perceptron）模型。感知机模型是机器学习二分类问题中的一个非常简单的模型。它的基本结构如下图所示：PLA理论解释对于二分类问题，可以使用感知机模型来解决。PLA的基本原理就是逐点修正，首先在超平面上随意取一条分类面，统计分类错误的点；然后随机对....
