论文Latex常用教程

页脚防挡

在合适的位置加上这个：

\IEEEpubidadjcol

Overleaf引用

最简单的方法是使用\bibitem的管理方法：

\begin{thebibliography}{1}

\bibitem{ams}
{\it{Mathematics into Type}}, American Mathematical Society. Online available: 

\bibitem{oxford}
T.W. Chaundy, P.R. Barrett and C. Batey, {\it{The Printing of Mathematics}}, Oxford University Press. London, 1954.

\end{thebibliography}

但是这种维护麻烦，每个条目都需要自己转化格式，因此更推荐使用bib文件 + BibTex的管理方式。具体来说在Overleaf Project下命名一个文件为xxx.bib（博主这里是Reference.bib）。在正文中引入你的bib文件：

\usepackage{cite}

\bibliographystyle{IEEEtran}
\bibliography{reference} %bib文件名

bib文件为BibleTex格式的引用，获取的方式如下

但是这种方法获取的引用经常没有boi版号，所以更推荐通过dblp获取详细的引用

表格

三线表常用的包是booktabs包，为了格内换行同时引入makecell包

\begin{table}[htbp]
    \begin{center}
        \caption{\textbf{Ablation studies of each component on SAR-AIRCRAFT 1.0 and the comparison is shown in terms of current known mAP(mAP) and unknown recall(U-Recall)}} % 表格下方描述
        \label{tab3} % 表格引用标签
        \begin{tabular}{ c | c | c | c | c | c } % 表格列布局
            \toprule
            Task IDs($\rightarrow$) & \multicolumn{2}{|c|}{Task 1} & \multicolumn{3}{c}{Task 2}\\ % multicolumn指占据多列
            \midrule
                    &U-Recall &mAP($\uparrow$) &\multicolumn{3}{c}{mAP($\uparrow$)}\\
                    &($\uparrow$) &\makecell{Current\\known} & \makecell{Previously\\known} & \makecell{Current\\known} & Both\\
            \midrule
            Full Model         &\textbf{44.67} &\textbf{85.52} &\textbf{84.67} & \textbf{49.00} &\textbf{79.57}\\
            \textit{w.o.} xx   &5.36           &84.37          &82.18          &48.08           &77.31 \\
            \textit{w.o.} xx   &0.07           &84.82          &81.72          &42.58           &76.13 \\
            \textit{w.o.} xx   &8.14           &84.61          &82.30          &43.91           &76.82 \\
            \bottomrule
        \end{tabular}
    \end{center}
\end{table}

标题与正文之间出现大片空白

原因：latex排版的问题，为了把整个页面撑满，自动扩大了段间距

\raggedbottom %加这个
 
\begin{document}
\end{document}

多行公式

% 多行公式单编号
\begin{equation}
\begin{aligned}
&\hat{C}_t = tanh(W_C\odot[h_{t-1},x_t]+b_C) \\
&i_t=\sigma(W_i\odot[h_{t-1},x_t]+b_i) \\ 
&f_t=\sigma(W_f\odot[h_{t-1},x_t]+b_f) \\
&C_t=f_t * C_{t-1}+i_t * \hat{C}_t \\
&o_t=\sigma(W_o\odot[h_{t-1},x_t]+b_o) \\
&h_t=o_t * tanh(C_t)
\end{aligned}
\end{equation}

算法排版

简单排版可以使用

\usepackage{algorithmic}
\usepackage{algorithm}

复杂推荐algorithm2e

\usepackage[ruled,lined,linesnumbered]{algorithm2e}

设置	作用
linesnumbered	显示行号
ruled	标题显示在上方，不加就默认显示在下方
vlined	代码段中用线连接
boxed	将算法插入在一个盒子里

一个例子：

\begin{algorithm}[t]
    \caption{Dual Supervised Pseudo-labeling}
    \begin{small}
        \BlankLine
        \KwIn{Input image $I$, backbone, RPN and head $G()$, Hungarian-Matcher $H()$, ground truth of known class $\{l, b\}$, known class count $C$, hyperparameter $\gamma, k$}%输入参数
	\KwOut{pseudo ground truth bounding box $b^*$ with pseudo label $l^*=C + 1$}%输出
        $q, \hat{l}, \hat{b} \leftarrow G(I)$\;
        $q_j,q_i \leftarrow H(q, l, b)$, where $i \in \overline{\mathcal{Q}}$ and $j \in \mathcal{Q}$\;
        \For{$i\leftarrow 1$ \KwTo $|\overline{\mathcal{Q}}|$}{
            \For{$c\leftarrow 1$ \KwTo $C+ 1$}{
                 $s_{c}^{cat} = f_{cls}(q_{ic}) \cdot f_{obj}(q_{ic})$ \;
                 $s_{cat} = s_{cat} + s_c^{cat}$ \;
    	}
        }
        \For{$i\leftarrow 1$ \KwTo $|\overline{\mathcal{Q}}|$}{
            \For{each $b_k^*$ in $b$}{
                $r = \arg\max IoU(\hat{b_i}, b^*_k)$
            }
            $\mathbf{s}^{loc}_i = 1 - IoU(\hat{b_i}, b_r)$
        }
        $s_p = s_{cat} \cdot (s_{loc})^\gamma$\;
        Select the $k$ unmatched queries $q*$ with $s_p$, $q* \leftarrow \text{Top}_k(s_p)$ \;
        $l^* = C + 1, b^* = \hat{b}_{idx(q^*)}$ \;
        \Return $\{l^*, b^*\}$
    \end{small}       
\end{algorithm}

表格每列宽度调整方法

最推荐的是使用tabularx这个包

\usepackage{tabularx}

设置格式： \begin{tabularx}{width}[pos]{preamble} width常用的就两个，分别为表示单栏的\linewidth与表示双栏的\textwidth，在前面可以加上一个浮点数表示比例，例如0.9\linewidth表示占据单栏的90%的宽度

preamble表示每一列的设置，用 "|" 间隔， 下面解释一个常见的设置：

>{\centering\arraybackslash}X

\centering表示居中，X表示均分总宽度，因此常见的等宽表格就是所有的宽度都设置为X，如果想要自定义宽度的话使用设置p：

>{\centering\arraybackslash}p{0.15\textwidth}

tip

注意，分割线也会占据一定的宽度，后面计算时需要留给分割线一些宽度

下面是两个常见的例子

\begin{table*}[htbp]
    \centering
    \caption{}
    \label{tab2}
    \begin{tabularx}{0.9\textwidth}{ >{\centering\arraybackslash}X | >{\columncolor{yellow!20}\centering\arraybackslash}X | >{\centering\arraybackslash}X | >{\centering\arraybackslash}X | >{\centering\arraybackslash}X | >{\centering\arraybackslash}X }

表格插入等高不等宽图片

常见的插入等宽高比例的图片的方法是通过figure与subfloat配合

tip

figure与figure*分别代表占据单栏宽度与占据双栏宽度

\begin{figure*}[!t]
    \centering
    \subfloat[]{\includegraphics[width=0.19\linewidth]{source.jpg}}
    \hfil
    \subfloat[]{\includegraphics[width=0.19\linewidth]{gt}}
    \hfil
    \subfloat[]{\includegraphics[width=0.19\linewidth]{OW-DETR_result.jpg}}
    \hfil
    \subfloat[]{\includegraphics[width=0.19\linewidth]{PROB_result.jpg}}
    \hfil
    \subfloat[]{\includegraphics[width=0.19\linewidth]{ours_result.jpg}}

    \vspace{-2em}

    \subfloat[Origin]{\includegraphics[width=0.19\linewidth]{source2.jpg}}
    \hfil
    \subfloat[GT]{\includegraphics[width=0.19\linewidth]{gt2.jpg}}
    \hfil
    \subfloat[OW-DETR~\cite{9879305}]{\includegraphics[width=0.19\linewidth]{OW-DETR_result2.jpg}}
    \hfil
    \subfloat[PROB~\cite{10204381}]{\includegraphics[width=0.19\linewidth]{PROB_result2.jpg}}
    \hfil
    \subfloat[DNOWSD(ours)]{\includegraphics[width=0.19\linewidth]{ours_result2.jpg}}

    \caption{}
    \label{}
\end{figure*}

这样对于想要插入等高但不等宽的图片不适用，想要浮动宽度可以考虑使用表格结构，也更方便添加图片标号
