insert formula
Interline formula (inline): use $...$ to enclose the formula. For example, the effect of $w^{[i]}$
: 
the formula occupies a single line and is automatically numbered:
\begin{
equation}
.....//你的公式
\end{
equation}
//比如
\begin{
equation}
S(x)=\frac{
1}{
1+e^{
-x}}
\end{
equation}
(Note: I already have four formulas here before, so this one is inserted and numbered 5) For the
specific formula to be inserted, see this big guy's blog:

You can use https://www.latexlive.com/ to edit the formula first and then copy the corresponding code into it
insert table

directly use this website to complete the form, and then paste the latex code automatically generated by the website to

I am too lazy to write in detail, just paste and copy to see the effect, you can compare and change:
three-line table:
\begin{

See the effect:
insert picture
First import the package:
\usepackage{
graphicx}
\graphicspath{
{
image/} } //image是你自己存放图片的文件夹
For example:
Created by yourself in the left menu bar
\begin{
figure}[t]
\centering
\includegraphics[width=8cm,height=10cm]{
dl.jpeg}\\{
这里是图片路径}
\caption{
决策树算法}\\图片的名称
\label{
fig:label4} \\图片的label
\end{
figure}
In this way, the pictures can have some relative position changes without causing problems such as difficulty in pagination.
For example:
**\begin{figure}[t]** A few explanations about this line
[t] I understand that this means how to insert pictures first
Optional parameters:
Optional parameter
h here (here)
t top of page (top)
b bottom of page (bottom)
p separate page (page)
Multiple can coexist at the same time
Insert a large picture occupying two columns:
just change the previous figure to figure*, and the others are the same
