## Overview

[vip](https://koalaverse.github.io/vip/index.html) is an R package for constructing **v**ariable **i**mportance **p**lots (VIPs). VIPs are part of a larger framework referred to as *interpretable machine learning* (IML), which includes (but not limited to): partial dependence plots (PDPs) and individual conditional expectation (ICE) curves. While PDPs and ICE curves (available in the R package [pdp](https://cran.r-project.org/package=pdp)) help visualize feature effects, VIPs help visualize feature impact (either locally or globally). An in-progress, but comprehensive, overview of IML can be found here: https://github.com/christophM/interpretable-ml-book. 

Many supervised learning algorithms can naturally emit some measure of importance for the features used in the model, and these approaches are embedded in many different packages. The downside, however, is that each package uses a different function and interface and it can be challenging (and distracting) to have to remember each one (e.g., remembering to use `xgb.importance()` for [xgboost](https://cran.r-project.org/package=xgboost) models and `gbm.summary()` for [gbm](https://cran.r-project.org/package=gbm) models). With [vip](https://cran.r-project.org/package=vip) you get one consistent interface to computing variable importance for many types of supervised learning models across a number of packages. Additionally, [vip](https://koalaverse.github.io/vip/index.html) offers a number of *model-agnostic* procedures for computing feature importance (see the next section) as well an experimental function for quantifying the strength of potential interaction effects. For details and example usage, visit the [vip package website](https://koalaverse.github.io/vip/index.html).

## Features

* **Model-based variable importance** - Compute variable importance specific to a particular model (like a *random forest*, *gradient boosted decision trees*, or *multivariate adaptive regression splines*) from a wide range of R packages (e.g., [randomForest](https://cran.r-project.org/package=randomForest), [ranger](https://cran.r-project.org/package=ranger), [xgboost](https://cran.r-project.org/package=xgboost), and many more). Also supports the [caret](https://cran.r-project.org/package=caret) and [parsnip](https://cran.r-project.org/package=parsnip) (starting with version 0.0.4) packages.

* **Permutation-based variable importance** - An efficient implementation of the permutation feature importance algorithm discussed in [this chapter](https://christophm.github.io/interpretable-ml-book/feature-importance.html) from [Christoph Molnar's *Interpretable Machine Learning* book](https://christophm.github.io/interpretable-ml-book/).

* **Shapley-based variable importance** - An efficient implementation of feature importance based on the popular [Shapley values](https://github.com/slundberg/shap) via the [fastshap](https://cran.r-project.org/package=fastshap) package. 

* **Variance-based variable importance** - Compute variable importance using a simple *feature importance ranking measure* (FIRM) approach. For details, see see [Greenwell et al. (2018)](https://arxiv.org/abs/1805.04755) and [Scholbeck et al. (2019)](https://arxiv.org/abs/1904.03959).

## Installation

```{r, eval=FALSE}

# The easiest way to get vip is to install it from CRAN:

install.packages("vip")

# Alternatively, you can install the development version from GitHub:

if (!requireNamespace("remotes")) {

  install.packages("remotes")

}

remotes::install_github("koalaverse/vip")

```
