Why R? conference is one of the best opportunities to learn secrets of data science from the renowned experts. This year we are happy to invite you for six keynote presentations, one invited workshop and eight regular workshops.

About Why R? 2019 conference

We are more than happy to announce that Why R? 2019 Conference will be organized by Why R? Foundation. The third official meeting of Polish R enthusiasts will be held in Warsaw from the 26th to 29th of September 2019. Since English is the official language of the meeting, we would love to invite R users from other countries.

Keynote speakers

• Steph Locke (Locke Data): with the increased importance of machine learning, we are becoming more and more concerned about the ethics of data science. Steph will tell us why the ethical development of machine learning models matters and how to ensure it.
• Marvin Wright (Leibniz Institute for Prevention Research and Epidemiology): the main developer of the ranger package, which ensures the fastest implementation of random forests in R, will talk about intricacies of this machine learning technique, especially tuning.
• Paula Brito (Universiy of Porto): multidimensional complex data, also known as symbolic data is often too complicated for classical statistical methods. Paula Brito, a researcher in the field of symbolic data analysis, will present her multivariate analysis methodologies implemented in the newest version of her package, MAINT.Data.
• Jakub Nowosad (Adam Mickiewicz University): R is well-known for its wide variety of geostatistic tools. Jakub Nowosad, a co-author of the Geocomputation with R, will share with us his knowledge on the best practices in the geographic data analysis.
• Sigrid Keydana (RStudio): since the arrival of the tensorflow package, R is opened to the number of applications offered by deep learning. Sigrid Keydana, will make an in-depth presentation on how to use the tfprobability package to assess uncertainties of the probabilistic model, including deep neural networks.
• Wit Jakuczyn (WLOG Solutions): R is popular in business applications. Wit will present challenges and solutions that appear nowadays during the cooperation with business related organizations.

Workshops

Invited workshop

Introduction to modern Generalized Additive Models in R: Generalized Additive Models (GAMs) GAMs are powerful enough to be a cornerstone of the Prophet software developed by Facebook. Matteo Fasiolo (University of Bristol), an author of two popular GAM-related R packages, will teach how to make the best use of these models.

Regular Workshops

Workshops last around 3 hours and take place in the morning or afternoon session.

Explainable artificial intelligence (XAI) path:

This path focuses on tools used in interpretive machine learning to understand decisions made by our models.

• auditor + DALEX: a powerful duet for validation and explanation of machine learning models
  • Alicja Gosiewska (Warsaw University of Technology, maintainer of the auditor package) and Tomasz Mikołajczyk will hold an introductory workshop about XAI in R. The workshop will mostly focus on tools from the DrWhy (drwhy.ai) universe.
• „Black is the new White” – using eXplainable Artificial Intelligence in Business
  • Marcin Chlebus (University of Warsaw) will guide participants of his workshop through the variety of XAI-related R packages, focusing on the business applications.

Regular Workshops

• Straightforward introduction to Deep Learning in R (with Keras) Mikołaj Olszewski and Mikołaj Bogucki iDash
• Shiny Basics Theo Roe, Jumping Rivers
• data.table introduction & time-series Jan Gorecki, H2O.AI
• Speeding up R wih C++ (Rcpp) – from basics to more advanced applications Piotr WóJcik, Faculty of Economic Sciences, University of Warsaw
• Machine Learning Pipelines and Reproducible Research with mlr3 and drake Jakob Richter (Technical University of Dortmund) and Patrick Schratz (LMU Munich).
