+## Introduction
+[An Introduction to Statistical Learning: With Applications in R](http://faculty.marshall.usc.edu/gareth-james/ISL/) is a great book to learn data science. However, the associated code is [R](https://www.r-project.org/about.html) which is a nice programming language for statisticians. There is a project named [ISLR-python](https://github.com/JWarmenhoven/ISLR-python) which ports the book to Python. I was inspired by the Python project and try to implement the introduced materials in this book to [Julialang](https://julialang.org/). Julia is a new language which is faster than C and more friendly to scientific computing than Python.

+## Library
+
+In this project, I use Julia v1.5.1 and the following library
+- [Plots.jl](https://github.com/JuliaPlots/PlotDocs.jl) for visualization
+- [CSV.jl](https://csv.juliadata.org/v0.4.0/) for reading csv file
+- [Clustering.jl](https://github.com/JuliaStats/Clustering.jl) for clustering algorithms 
+- [LIBSVM.jl](https://github.com/JuliaML/LIBSVM.jl) for LibSVM implementation
+- [StatsPlots.jl](https://github.com/JuliaPlots/StatsPlots.jl) for plotting statistic
+- [DataFrames.jl](https://github.com/JuliaData/DataFrames.jl) for data frame 
+- [GLM.jl](https://github.com/JuliaStats/GLM.jl) for generalized linear model
+- [Distributions.jl](https://github.com/JuliaStats/Distributions.jl) for stat distributions
