大家好,我是Mac Jiang,今天和大家分享Coursera-NTU-機器學習基石(Machine Learning Foundations)-作业四 Q13-20的MATLAB实现. 曾经的代码都是通过C++实现的.可是发现C++实现这些代码太麻烦.这次作业还要频繁更改參数值,所以选择用MATLAB实现了.与C++相比.MATLAB实现显然轻松非常多.在数据导入方面也更加方便.我的代码尽管可以得到正确答案,可是当中可能有某些思想或者细节是错误的,假设各位博友发现,请及时留言纠正,谢谢.再次声…

一.Training of a Single-Layer Neural Network 1 Delta Rule Consider a single-layer neural network, as shown in Figure 2-11. In the figure, d i is the correct output of the output node i. Long story short, the delta rule adjusts the weight as the follow…

昨天总结了深度学习的资料,今天把机器学习的资料也总结一下(友情提示:有些网站需要"科学上网"^_^) 推荐几本好书: 1.Pattern Recognition and Machine Learning (by Hastie, Tibshirani, and Friedman's ) 2.Elements of Statistical Learning(by Bishop's) 这两本是英文的,但是非常全,第一本需要有一定的数学基础,第可以先看第二本.如果看英文觉得吃力,推荐看一下下面…

Logistic regression is a method for classifying data into discrete outcomes. For example, we might use logistic regression to classify an email as spam or not spam. In this module, we introduce the notion of classification, the cost function for logi…

Machine Learning Lab1 打算把Andrew Ng教授的#Machine Learning#相关的6个实验一一实现了贴出来- 预计时间长度战线会拉的比較长(毕竟JOS的7级浮屠还没搞定.) ----------------------------------------------------------------------------------------------------------------------------------- 实验内容: 线性拟合 实验材…
