Explore Correlations Between Variables in a Machine Learning Model
When exploring data or models we often examine variables one by one. This analysis is incomplete if the relationship between these variables is not taken into account. The 'corrgrapher' package facilitates simultaneous exploration of the Partial Dependence Profiles and the correlation between variables in the model. The package 'corrgrapher' is a part of the 'DrWhy.AI' universe.
Tools for Archiving, Managing and Sharing R Objects via GitHub
The extension of the 'archivist' package integrating the archivist with GitHub via GitHub API, 'git2r' packages and 'httr' package.
Stochastic Gradient Descent log-Likelihood Estimation in Cox Proportional Hazards Model
Estimate coefficients of Cox proportional hazards model using stochastic gradient descent algorithm for batch data.
Tools for Eurostat Open Data
Tools to download data from the Eurostat database < https://ec.europa.eu/eurostat> together with search and manipulation utilities.
Assisted Model Building, using Surrogate Black-Box Models to Train Interpretable Spline Based Additive Models
Builds generalized linear model with automatic data transformation. The 'xspliner' helps to build simple, interpretable models that inherits informations provided by more complicated ones. The resulting model may be treated as explanation of provided black box, that was supplied prior to the algorithm.
Variable Importance via Oscillations
Provides an easy to calculate local variable importance measure based on Ceteris Paribus profile and global variable importance measure based on Partial Dependence Profiles.
International Assessment Data Manager
Provides tools for importing, merging, and analysing data from international assessment studies (TIMSS, PIRLS, PISA, ICILS, and PIAAC).

Set of functions that access information about deputies and votings in Polish diet from webpage < http://www.sejm.gov.pl>. The package was developed as a result of an internship in MI2 Group - < http://mi2.mini.pw.edu.pl>, Faculty of Mathematics and Information Science, Warsaw University of Technology.
Explain Interactions in 'XGBoost'
Structure mining from 'XGBoost' and 'LightGBM' models. Key functionalities of this package cover: visualisation of tree-based ensembles models, identification of interactions, measuring of variable importance, measuring of interaction importance, explanation of single prediction with break down plots (based on 'xgboostExplainer' and 'iBreakDown' packages). To download the 'LightGBM' use the following link: < https://github.com/Microsoft/LightGBM>. 'EIX' is a part of the 'DrWhy.AI' universe.
Explaining Correlated Features in Machine Learning Models
Tools for exploring effects of correlated features in predictive
models. The predict_triplot() function delivers instance-level explanations
that calculate the importance of the groups of explanatory variables. The
model_triplot() function delivers data-level explanations. The generic plot
function visualises in a concise way importance of hierarchical groups of
predictors. All of the the tools are model agnostic, therefore works for any
predictive machine learning models. Find more details in Biecek (2018)
