Description Important functions Example datasets

Description

This package aims to help locally fit and visualize interpretable models similarly to LIME methodology. Interface provided by mlr package is used. Tools are provided to create a simulated dataset of similar observations, fit chosen white box models (GLM and CART in particular) and visualize them. The methodology is based on Tulio Ribeiro, Singh, Guestrin (2016) <doi:10.1145/2939672.2939778>. More details can be found in Staniak, Biecek (2018) https://arxiv.org/abs/1804.01955.

Important functions

sample_locally generates a dataset that will be used for local exploration. add_predictions adds black box model predictions to simulated dataset. fit_explanation fits a chosen white box model to simulated dataset. generic plot function visualizes fitted model. local_approximation function can be used with DALEX explainers to perform all the steps of local model exploration.

Example datasets
