Enabling reproducibility in data science - learn why it matters and how you can do it




How do I make sure that independent researchers will be able to reproduce my research results? Why is that even important and what tools or methods are there to achieve this goal? Keeping reproducibility in mind from the very start of a project will help you in the long run and greatly add to the quality of your research. In this event organized by the Helmholtz Open Science Office and HIDA, we will focus on digital reproducibility and best practices for data science.

We will start off the event with two short lectures on reproducibility, first in the context of open science and second in relation to data science and machine learning. Afterwards, you will have the choice to attend and actively take part in one of these three workshops:

  1. Practical steps towards reproducible research
  2. Foundations of research software publication
  3. Scientific metadata: Fundamentals of structured and standardized research data annotation

How to participate?

Participation is free of charge. Please register for the event by clicking on "Apply for Participation". During the registration process, you will be asked to choose one of the three workshops on offer. They will take place in parallel so you can only attend one. Please contact us if you would like to see more training events like this one.


The Helmholtz Open Science Office supports the Helmholtz Association as a service provider in shaping the cultural change towards open science. It represents Helmholtz in various open science initiatives, is involved in third-party funded projects, and in this way communicates the Helmholtz positions on open science on a national and international level.

HIDA - the Helmholtz Information & Data Science Academy - is Germany’s largest postgraduate training network in the field of information and data science. We prepare the next generation of scientists for a data-heavy future of research.

      Impulse lecture: Open science & reproducibility 20m

      Research is reproducible when it is possible to (independently) recreate the same results from the same data and same code/analysis as used by the original researcher or team of researchers. Reproducibility enhances collaboration and transparency in science and supports reusability of scientific products. This closely links with the open science endeavour towards the cultural change in science and science communication. Open science aims for a more effective and open exchange of information within science and the promotion of methods and the transfer of scientific results to society, the economy, and politics.

      Impulse lecture: Reproducibility in data science and machine learning 20m

      Machine Learning is becoming ubiquitous in many scientific domains. However, practitioners struggle to apply every new addition to the Machine Learning market on their data with comparable effects than published. In this talk, I'd like to present recent observations on reproducibility of Machine Learning results and how the community strives to tackle related challenges.

        Foundations of research software publication 2h

        We will provide you with actionable advice about how to prepare your research code before publishing it or submitting it alongside a research publication.

        This talk will cover the following topics:
        • Code repository structuring
        • Minimum coding practices
        • Documentation
        • Open source licensing
        • Minimum software release practices
        • Software citation

        We will discuss these topics at the example of a data analysis script and will focus on minimum practices for every topic.

        Practical steps towards reproducible research 2h

        In this workshop we will look at four key steps to get started with reproducible research:

        (1) Get organized
        (2) Use Open Source Software
        (3) Use Version Control
        (4) Make your work available online.

        Although reproducible research practices can first seem intimidating, we will find a way to get started that works for you.

        Scientific metadata: Fundamentals of structured and standardized research data annotation 2h

        This course is limited to 25 participants

        Did you ever feel lost in incomprehensible research data documentation? This session introduces the basics of machine-readable research data annotation with domain-specific metadata schemas and standards. Learn, why accurate and harmonized description of research data is key for scientific exchange and how to find a suitable metadata framework in your research domain.
