Introduction and affiliations

My name is Rianne and I develop data analysis methods. I am a PhD Candidate at Eindhoven University of Technology and study the Exceptional Model Mining framework. We work on developing solutions for heterogeneous datasets with time-dependent attributes. My supervisors are dr. Wouter Duivesteijn and prof. Mykola Pechenizkiy.

Additionally, I work on Missing Data methods, particularly the process of generating missing values in complete datasets. Under supervision of prof. Stef van Buuren and dr. Gerko Vink, I developed a multivariate amputation procedure and implemented the method in an R-function (ampute in package mice) and python module (pyampute).

I find it important that my work can be used for real-world problems (e.g. in health care) and enjoy collaborating on projects. Please contact me if you have questions or seek opportunities to work together.

Software development

1. ampute in R-package mice

library(mice)
?ampute

R-function ampute is the implementation of a multivariate amputation procedure: a method for generating missing data in complete datasets. With ampute, it is straightforward to generate missing values in multiple variables, with different missing data proportions and varying underlying missingness mechanisms. Read the article or the vignette to learn more.

2. parlMICE

For large datasets or when you want to impute with a large number of imputations, multiple imputation with mice in R-package mice may have a long run time. As a solution, Gerko Vink and I created wrapper function parlMICE, which allows for a parallel run of mice.

The function is now part of package mice under the name parlmice.

library(mice)
?parlmice

All information can be found in the github repo or in the vignette.

3. pyampute: the first Python library for data amputation

Library pyampute provides the multivariate amputation methodology to the Python community, and it does more. It has improved default settings, allows for a combined MAR+MNAR mechanism, for custom probability functions and since it is compatible with scikit-learn’s fit and transform paradigm, seamless integration in data processing pipelines becomes easy.

Find plenty of examples in pyampute’s documentation. Davina’s presentation at SciPy22 can be found here.

Install using pip or from source:

pip install pyampute
git clone https://github.com/RianneSchouten/pyampute.git
pip install ./pyampute

Personal development

To develop myself as a teacher, I am participating in the University Teaching Qualification (UTQ) Training Program.

Other courses that I participated in are Project management (PROOF TU/e 2020), Introduction to Process Mining (Fluxicon, 2020), Learning and Reasoning (SIKS, 2021) and Communication Styles (PROOF TU/e 2021).
