# Unsupervised Learning in R

Unsupervised machine learning is a class of algorithms that identifies patterns

in unlabeled data, i.e. without considering an outcome or target. This workshop

will describe and demonstrate powerful unsupervised learning algorithms used for

**clustering** (hdbscan, latent class analysis, hopach), **dimensionality

reduction** (umap, generalized low-rank models), and **anomaly detection** (isolation forests).

Participants will learn how to structure unsupervised

learning analyses and will gain familiarity with example code that can be

adapted to their own projects.

**Author**: [Chris Kennedy](http://github.com/ck37)

## Prerequisites

This is an intermediate machine learning workshop. Participants should have

significant prior experience with R and RStudio, including manipulation of data

frames, installation of packages, and plotting.

**Prerequisite workshops**

 * [R Fundamentals](https://github.com/dlab-berkeley/R-Fundamentals) or similar training in R basics.

 

**Recommended workshops**

 * [Machine Learning in R](https://github.com/dlab-berkeley/Machine-Learning-in-R) or other supervised learning experience.

## Technology requirements

Participants should have access to a computer with the following software:

 * [R version 3.6](https://cran.rstudio.com/) or greater

 * [RStudio](https://rstudio.com/products/rstudio/download/#download)

 * [RTools](https://cran.r-project.org/bin/windows/Rtools/) - if using Windows

 

## Initial steps for participants

To prepare for the workshop, please download the materials and work through the package installation in `0-install.Rmd`. Please report any errors to the [GitHub issue queue](https://github.com/dlab-berkeley/Unsupervised-Learning-in-R/issues).

There is also an [RStudio Cloud workspace](https://rstudio.cloud/project/930459) that can be used.

 

## Reporting errors or giving feedback

Please [create a GitHub issue](https://github.com/dlab-berkeley/Unsupervised-Learning-in-R/issues) to report any errors or give feedback on this workshop.
