Machine Learning for Imbalanced Datasets

Chapter 1 Prerequisites
This is a sample book written in Markdown. You can use anything that Pandoc’s Markdown supports, e.g., a math equation \(a^2 + b^2 = c^2\).
The bookdown package can be installed from CRAN or Github:
{r eval=FALSE}install.packages("bookdown") # or the development version # devtools::install_github("rstudio/bookdown")
Remember each Rmd file contains one and only one chapter, and a chapter is defined by the first-level heading #.
To compile this example to PDF, you need XeLaTeX. You are recommended to install TinyTeX (which includes XeLaTeX): https://yihui.name/tinytex/.
bookdown::render_book("index.Rmd", "bookdown::gitbook")

# Introduction {#intro}
## Applications
You can label chapter and section titles using `{#label}` after them, e.g., we can reference Chapter \@ref(intro). If you do not manually label them, there will be automatic labels anyway, e.g., Chapter \@ref(methods).
Figures and tables with captions will be placed in `figure` and `table` environments, respectively.
```r
par(mar = c(4, 4, .1, .1))
plot(pressure, type = 'b', pch = 19)
Figure 1.1: Here is a nice figure!
Reference a figure by its code chunk label with the fig: prefix, e.g., see Figure 1.1. Similarly, you can reference tables generated from knitr::kable(), e.g., see Table 1.1.
knitr::kable(
head(iris, 20), caption = 'Here is a nice table!',
booktabs = TRUE

You can write citations, too. For example, we are using the bookdown package (Xie 2021) in this sample book, which was built on top of R Markdown and knitr (Xie 2015).
