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.
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.
plot function visualizes fitted model.
local_approximation function can be used with DALEX explainers to perform
all the steps of local model exploration.
