Conditions: For the data set D, there exists a $\displaystyle W_{f}$ which satisfies that for every n, $y_{n}W_{f}^{T}X_{n}>0$. $\displaystyle W_{T+1}=W_{T}+y_{n(T)}X_{n(T)}$ AND $\displaystyle y_{n(T)}W_{T}^{T}X_{n(T)}<0$. So, let us set $\rho = \m…

之前在<机器学习---感知机(Machine Learning Perceptron)>一文中介绍了感知机算法的理论知识,现在让我们来实践一下. 有两个数据文件:data1和data2,分别用于PLA和Pocket Algorithm.可在以下地址下载:https://github.com/RedstoneWill/MachineLearningInAction/tree/master/Perceptron%20Linear%20Algorithm/data. 先回顾一下感知机算法: 1,初始…
