Hackathon XAI 2018 - 'Explainability in Lifestyle Support'

Soest | Stayokay • 06 Nov 2018 - 07 Nov 2018

The TNO Hackathon Explainable AI 2018 takes place from 6 to 7 November 2018. Here, we challenge you to prototype innovative ways to increase transparency, deeper understanding and persuasiveness by integrating explainable AI (XAI) in lifestyle support applications. Registration is free and will include an overnight stay at Stayokay Soest and meals during the two days.

Current state of the art lifestyle-support applications offer context-aware advice, but lack giving insights in how (and why) such advice was formed. At TNO, we have been working on a number of novel XAI methods that are able to enrich the inferred advice. The goal of the hackathon is to build a next-level support application by offering the best explainability. You will be working on a lifestyle-related use case that includes offering personalized advice about effective coping strategies to diabetics or people with the risk to develop diabetes.

We will provide you with all the ingredients to build a basic prototype: a rich dataset, pre-trained advice models, TNO’s library of XAI modules and tablets to implement user interaction. From there, you can take it as far as you can. Whether you focus on improving the XAI algorithms, combining multiple XAI models, improve explanations based on user feedback, building a slick user interface or all of them; it is entirely up to you!

During the hackathon, there will be speakers to provide more insight into the domains and research fields. Also, our experts and coaches will make sure you are up and running in no time.
This will be two days of hard and challenging work. There will be the opportunity to work as late as you want, however we will also provide you with a place to sleep at the Stayokay.


During the hackathon inspiring speakers will provide you with new thoughts and ideas. Amongst others will be Mark Neerincx (full professor in Human-Centered Computing at the Delft University of Technology, and principal investigator at TNO Perceptual and Cognitive Systems), Catholijn Jonker (full professor of Interactive Intelligence at the Delft University of Technology) and Robert-Jan Sips (Chief Technology Officer of myTomorrows).

Jury and prizes

At the end of the hackathon, each group will give a short pitch of their targeted application of explainability in lifestyle support. The pitch will be followed by a demonstration of your prototype and reflection on the design choices. Pitches and demos are rated by a jury panel of professionals from relevant fields of expertise, as well as a ranking from the other participating groups.
The winning team will win a prize worth 1000 euros, the runner up 500 euro.

Application guidelines

We encourage you to apply with a team of 4 – 5 persons. The intended audience is undergraduate students, master students, PhD Contrastive Explanations with Local Foil Trees students and postdocs from around the world. Applying as a multidisciplinary team will be beneficial because the hackathon will comprise aspects of machine learning, XAI, visualization, user interaction, human behavior studies and of course serious programming efforts. You can also register individually. We will make sure you will be teamed up with others.


You can register by sending an email to hackathon-xai@tnodatalab.nl. All applicants must provide a CV with a short motivation letter (one or two paragraphs). From all applications, the participants with the best motivations and plans will be selected to enter the hackathon.


Application is free and will include an overnight stay at Stayokay Soest and meals during the two days.
