n * 1的矩阵就是向量,如下就是4维向量 向量坐标表示:Yi= ithrow 矩阵运算 加法/减法 加法减法只要将对应的元素相加/相减即可,只适用于相同维度的矩阵之间. 标量乘法/除法 矩阵向量乘法 n * m维度的矩阵 * m维度的向量 = n维度的向量 实际运用: 假设有方程hθ(x) = -40 + 0.25*x x为房屋面积,hθ(...
[Week 1] Machine-learning Notes 4 ——Linear Algebra(一些线性代数基础) 矩阵实际上是二维数组的另一个名字:而维度(Dimension of matrix)就是矩阵的行数乘以列数(一般分开说,比如4行2列,不说8维矩阵,只说4X2的矩阵,意思就是维度是4X2维,即4X2matrix,)。 但是矩阵在书写上也有些不同,如下: Paste_Image....
一、创作背景 通过看其他人在kaggle上分享的notebook以及自己的一些理解,记录一下Linear Regression的学习过程,也算是完成作业中的report.pdf。 二、Linear Regression(预测PM2.5) 1、准备工作 (1)作业要求(如图一所示) 图一 (2)train.csv、test.csv 链接:https://pan.baidu.com/s/1ZeOASD7SdyMUYwjo0uDaqA ...

So what you should usually do is, unless otherwised specified, you should assume we are using one index vectors. In fact, throughout the rest of these videos on linear algebra review, I will be using one index vectors. But just be aware that when we are talking about machine learning ap...
