Juxtapose ML models in the Arena. Let the most credible one win!
The Arena performs detailed comparative analysis of the ML models regardless of their internal structure or the language in which they are trained.TL;DR: Piotr Piątyszek from MI2DataLab developed a new R package for interactive juxtapositioning of multiple ML models: http://arenar.drwhy.ai/Most predictive ML models are based on a simple assumpt...

modelStudio and The Grammar of Interactive Explanatory Model Analysis
The new version of modelStudio has recently been released on CRAN.modelStudio is an R package that automates the exploration of ML models and allows for interactive examination. It works in a model agnostic fashion, therefore is compatible with most of the ML frameworks (e.g. mlr/mlr3, xgboost, caret, h2o, scikit-learn, lightGBM, keras/tensorflow...

xai2cloud: Convert a predictive model into an XAI cloud service
TL;DRThe xai2cloud package allows for simple deployment of an R model as a cloud service. Any predictive model from the local R console can be converted into a REST service available remotely in the DigitalOcean cloud. GET and POST methods are created automatically for elementary XAI methods such as Break Down and Ceteris Paribus. There will be m...

fairmodels: let’s fight with biased Machine Learning models (part 1 — detection)
fairmodels: let’s fight with biased Machine Learning models (part 1 — detection)Author: Jakub WiśniewskiTL;DRThe fairmodels R Package facilitates bias detection through model visualizations. It implements few mitigation strategies that could reduce the bias. It enables easy to use checks for fairness metrics and comparison between differ...

R packages for eXplainable Artificial Intelligence
Joint work with Szymon Maksymiuk and Alicja Gosiewska.The growing demand for fast and automated development of predictive models has contributed to the popularity of machine learning frameworks. ML frameworks allow us to quickly build models that maximize a selected performance measure. However, it turned out that as the result we are getting bla...

Plotting the excessive number of deaths in 2020 by age (with the eurostat package)
Number of deaths in consecutive weeks. See the second plot for the whole story.Recently there have been several blog entries showing excessive number of deaths in different countries.Recently I discovered that in the eurostat database (1) one can find current data on the number of deaths, (2) this number is broken down by age, gender and geograp...

Summarise the 2020 with R and rgl
The end of the year is a great time to summarize accomplishments of the team. This year in MI2DataLab we summarized good things that happend in the form of baubles on the christmas tree (yes, this is the only known exception for using 3D plots). Each color of a bauble represents a different kind of result (yellow for articles, red for the package...
