|

<p>众所周知，SVD(奇异值分解)可以用于最小二乘法求齐次线性方程组$A\vec{x}=\vec{0}$的解。我看了很多资料，大多使用数学公式推导，得出结论。但是，曾经线性代数差点挂科的我，总觉得有些蹊跷。想了两天，终于有了一些感性的认知（不一定是对的😂），赶紧记录下来。</p>
|
||||
<h2 id="矩阵有何意义"><a class="header-anchor" href="#矩阵有何意义">¶</a>矩阵有何意义</h2>
|
||||
<p>按照我的理解，一个矩阵的实际意义是对应一个线性变换，这个变换可以理解为瞬间运动。例如，一个旋转矩阵，</p>
|
||||
<p>$$<br>
|
||||
A=\begin{bmatrix}<br>
|
||||
cos\theta & sin\theta \\\<br>
|
||||
-sin\theta & cos\theta<br>
|
||||
\end{bmatrix}<br>
|
||||
$$</p>
|
||||
<p>它的意思是，把一个向量顺时针旋转$\theta$。也就是说，给定一个$\vec{v_1}=[-1, 1]^T$, 那么变换的结果就是$\vec{v_2}=A\vec{v_1}=[1, 1]^T$.</p>
|
||||
<p>除了旋转，矩阵还可以表示包括缩放，投影在内的所有<strong>线性变换</strong>。</p>
|
||||
<p>十分推荐大家去看 3Blue1Brown 的 <em>线性代数的本质</em>，B 站有<a href="https://www.bilibili.com/video/BV1ys411472E" target="_blank" rel="noopener">官方翻译版</a>，它完全颠覆了我对线性代数的认知。</p>
|
||||
<h2 id="SVD到底干了什么"><a class="header-anchor" href="#SVD到底干了什么">¶</a>SVD到底干了什么</h2>
|
||||
<p>$$<br>
|
||||
A = U\Sigma V^T<br>
|
||||
$$</p>
|
||||
<p>SVD把矩阵$A(m\times n)$分解成了,</p>
|
||||
<ul>
|
||||
<li>$U(m\times m)$: 左奇异矩阵</li>
|
||||
<li>$\Sigma(m\times n)$: 奇异值矩阵</li>
|
||||
<li>$V(n\times n)$: 右奇异矩阵</li>
|
||||
</ul>
|
||||
<p>重点来了，SVD的意思就是，把一个本来由矩阵$A$表示的变换，转化成一个由$U,\Sigma,V$表示的变换。这个变换是，把一个向量，从以$V$为基向量的空间线性变换到成以$U$为基向量的空间中去（$\Sigma$的意义可以说是缩放，待证实，暂时忽略）。这样我们就可以更深入的理解这个变换了。</p>
|
||||
<p>例如旋转$\vec{v_1}$90度得到$\vec{v_2}$，</p>
|
||||
<p><img src="//davidz.cn/static/blog/2020-06-04-SVD-for-homogeneous-linear-equation/rotate90.svg" alt="rotate 90"></p>
|
||||
<p>其中，</p>
|
||||
<p>$$<br>
|
||||
U=\begin{bmatrix}<br>
|
||||
0 & 1 \\\<br>
|
||||
1 & 0<br>
|
||||
\end{bmatrix}<br>
|
||||
$$</p>
|
||||
<p>$$<br>
|
||||
\Sigma=\begin{bmatrix}<br>
|
||||
1 & 1<br>
|
||||
\end{bmatrix}<br>
|
||||
$$</p>
|
||||
<p>$$<br>
|
||||
V=\begin{bmatrix}<br>
|
||||
-1 & 0 \\\<br>
|
||||
0 & 1<br>
|
||||
\end{bmatrix}<br>
|
||||
$$</p>
|
||||
<p>也就是说，矩阵$A$可以被理解为，我们把一个向量$\vec{v_1}$，从以$\vec{e_1}=[-1, 0]^T,\vec{e_2}=[0, 1]^T$为基向量的空间线性变换到了以$\vec{e_1}=[0, 1]^T,\vec{e_2}=[1, 0]^T$为基向量的空间中。这个变换表现为旋转了90度。</p>
|
||||
<h2 id="所以如何理解"><a class="header-anchor" href="#所以如何理解">¶</a>所以如何理解</h2>
|
||||
<p>说回求齐次线性方程组$Ax=0$的解来。</p>
|
||||
<p>按照矩阵的意义，我们这里要求的是，已知一个线性变换$A$，给定一个$\vec{x}$，使得线性变换后的结果为$\vec{0}$。</p>
|
||||
<p>此时非常重要的是，如果$x=\vec{0}$，那一定成立，但是我们想找一个非平凡的解。</p>
|
||||
<p>我们暂时不关心这个解是否存在，也就是说如果不存在，我们就找个最接近的（最小二乘法思想），我们直接使用SVD分解矩阵$A$，得到对应的$U,\Sigma,V$。</p>
|
||||
<p>按照SVD的作用，我们现在可以说，矩阵$A$这个线性变换，把一个$\vec{x}$，从以$V$为基向量的空间线性变换到了以$U$为基向量的空间中，而我们想找，在以$V$为基向量的空间中，哪个向量会在投影后趋近于或者等于$\vec{0}$。更重要的是，我们只在乎这个向量的方向，而不在乎他的大小，因为它等于$\vec{0}$是个平凡解，这就像最小二乘法中，我们规定$|\vec{x}|=1$。</p>
|
||||
<p>这时，答案就开始变得清晰了，因为我们想找的$\vec{x}$，应该就是$V$这组基向量中特异值$\sigma$最小的那一个$\vec{e_{min}}$，也就是说$\vec{x}=\vec{e_{min}}$。此时有两种情况，</p>
|
||||
<ol>
|
||||
<li>$\sigma=0$， 那么$\vec{x}$投影后的就是$\vec{0}$。</li>
|
||||
<li>$\sigma\neq0$，那么$\vec{x}$投影后是使$A\vec{x}$最小的解。因为如果$\vec{x}\neq\vec{e_{min}}$，也就是说它偏离了$\vec{e_{min}}$，那么它一定由$\vec{e_{min}}$和另一个基向量线性组合，而无论怎么组合，$\sigma_{combine}\geq\sigma_{min}$。</li>
|
||||
</ol>
|
||||
<p>因此，我们求解$A\vec{x}=0$的过程就是，</p>
|
||||
<ol>
|
||||
<li>$U,\Sigma,V^T=SVD(A)$</li>
|
||||
<li>$\vec{x}=V[:, -1]$</li>
|
||||
</ol>

众所周知，SVD(奇异值分解)可以用于最小二乘法求齐次线性方程组$A\vec{x}=\vec{0}$的解。我看了很多资料，大多使用数学公式推导，得出结论。但是，曾经线性代数差点挂科的我，总觉得有些蹊跷。想了两天，终于有了一些感性的认知（不一定是对的😂），赶紧记录下来。

¶前言

闲来无聊，在家折腾 DevOps，第一步当然是部署一个 Jenkins 啦，然而一顿操作猛如虎，插件一个都下载不下来，总不能给 Jenkins 加个代理吧，所以有了下面这一通折腾。

¶原因
|
||||
|

根据经验，国外这些软件下载失败基本上都是因为链接不上服务器，换个源就好了...

众所周知，SVD(奇异值分解)可以用于最小二乘法求齐次线性方程组$A\vec{x}=\vec{0}$的解。我看了很多资料，大多使用数学公式推导，得出结论。但是，曾经线性代数差点挂科的我，总觉得有些蹊跷。想了两天，终于有了一些感性的认知（不一定是对的😂），赶紧记录下来。

¶前言
|
||||
这是 ANU COMP2310的第一次大作业，历时一个月左右，也是这个学期我写的最认真的一次作业，所以在博客搭建伊始，我先把这个记录下来。

哈哈哈，这是一个经典的测试页面。

一直以来都想拥有一个自己的博客，从WordPress开始，到Typecho，再到Halo，甚至中途尝试用 Django 自己实现了一个（不过样子也太丑了），虽然说一直在捣鼓博客，但是从来都是安装=>部署=>安装插件=>选...

¶Q
|

我在博客中写公式的时候使用双斜线\\来代表换行，效果是这样的，
|
||||
$$
|
||||
\begin{bmatrix}
|
||||
cos\theta & sin\theta \
|
||||
-sin\theta & cos\theta
|
||||
\end{bmatrix}
|
||||
$$
|

那么如何插入多行公式...

众所周知，SVD(奇异值分解)可以用于最小二乘法求齐次线性方程组$A\vec{x}=\vec{0}$的解。我看了很多资料，大多使用数学公式推导，得出结论。但是，曾经线性代数差点挂科的我，总觉得有些蹊跷。想了两天，终于有了一些感性的认知（不一定是对的😂），赶紧记录下来。

¶Q
|
||||
我在博客中写公式的时候使用双斜线\\来代表换行，效果是这样的，
|
||||
$$
|
||||
\begin{bmatrix}
|
||||
cos\theta & sin\theta \
|
||||
-sin\theta & cos\theta
|
||||
\end{bmatrix}
|
||||
$$
|
||||
那么如何插入多行公式...

众所周知，SVD(奇异值分解)可以用于最小二乘法求齐次线性方程组$A\vec{x}=\vec{0}$的解。我看了很多资料，大多使用数学公式推导，得出结论。但是，曾经线性代数差点挂科的我，总觉得有些蹊跷。想了两天，终于有了一些感性的认知（不一定是对的😂），赶紧记录下来。

¶前言
|

闲来无聊，在家折腾 DevOps，第一步当然是部署一个 Jenkins 啦，然而一顿操作猛如虎，插件一个都下载不下来，总不能给 Jenkins 加个代理吧，所以有了下面这一通折腾。
|
||||
¶原因
|
||||
|
||||
根据经验，国外这些软件下载失败基本上都是因为链接不上服务器，换个源就好了...

|

<p>众所周知，SVD(奇异值分解)可以用于最小二乘法求齐次线性方程组$A\vec{x}=\vec{0}$的解。我看了很多资料，大多使用数学公式推导，得出结论。但是，曾经线性代数差点挂科的我，总觉得有些蹊跷。想了两天，终于有了一些感性的认知（不一定是对的😂），赶紧记录下来。</p>
|
||||
|
||||
<p>按照我的理解，一个矩阵的实际意义是对应一个线性变换，这个变换可以理解为瞬间运动。例如，一个旋转矩阵，</p>
|
||||
<p>$$<br>
|
||||
A=\begin{bmatrix}<br>
|
||||
cos\theta & sin\theta \\\<br>
|
||||

<p>众所周知，SVD(奇异值分解)可以用于最小二乘法求齐次线性方程组$A\vec{x}=\vec{0}$的解。我看了很多资料，大多使用数学公式推导，得出结论。但是，曾经线性代数差点挂科的我，总觉得有些蹊跷。想了两天，终于有了一些感性的认知（不一定是对的😂），赶紧记录下来。</p>

<p>一直以来都想拥有一个自己的博客，从<a href="https://wordpress.org/" target="_blank" rel="noopener">WordPress</a>开始，到<a href="http://typecho.org/" target="_blank" rel="noopener">Typecho</a>，再到<a href="https://halo.run/" target="_blank" rel="noopener">Halo</a>，甚至中途尝试用 Django 自己实现了一个（不过样子也太丑了），虽然说一直在捣鼓博客，但是从来都是安装=>部署=>安装插件=>选择主题=>发布第一篇文章，然后就没有然后了。</p>

|

<p>我在博客中写公式的时候使用双斜线<code>\\</code>来代表换行，效果是这样的，</p>

\begin{bmatrix}<br>

-sin\theta & cos\theta<br>

<p>那么如何插入多行公式呢？</p>
|

<h2 id="A"><a class="header-anchor" href="#A">¶</a>A</h2>

<p>根据<a href="https://github.com/gcushen/hugo-academic/issues/291#issuecomment-334746889" target="_blank" rel="noopener">Multiple lines Mathjax formulas flattened to one line</a>，应该插入 <em>六个</em> 斜线来表示换行，应该是由于Markdown的渲染机制导致<code>\\</code>被反义。</p>

<p>计算机这个专业，有很多报告要做。在山威的时候，报告格式没有什么限制 Word，PDF 都可以，那个时候我开始使用 Markdown 作为我的排版工具，因为实在是没有时间经历去研究 Word 的各种高级功能（<s>主要是懒</s>）。Markdown 十分简单，易学，在<a href="https://github.com" target="_blank" rel="noopener">Github</a>等计算机专业相关平台使用也非常广泛，还可以通过各种模板快速生成<strong>好看</strong>，<strong>美观</strong>，<strong>专业</strong>的文档。</p>
|
||||
<p>后来到了澳国立，老师教授们开始极力鼓吹 Latex 和 PDF，基本上算是软性要求我们使用 Latex 编写，还规定了衬线...</p>
|
||||
<p>我在博客中写公式的时候使用双斜线<code>\\</code>来代表换行，效果是这样的，</p>
|
||||
<p>$$<br>
|

\begin{bmatrix}<br>
|

cos\theta & sin\theta \<br>
|

-sin\theta & cos\theta<br>

$$</p>
|

<p>那么如何插入多行公式呢？</p>

<p>根据<a href="https://github.com/gcushen/hugo-academic/issues/291#issuecomment-334746889" target="_blank" rel="noopener">Multiple lines Mathjax formulas flattened to one line</a>，应该插入 <em>六个</em> 斜线来表示换行，应该是由于Markdown的渲染机制导致<code>\\</code>被反义。</p>
