A few updates:

    1. We are very proud to be hosting a health-data science meetup at JADS: see for updates on our events and activities: https://medium.com/data-science-backchannel
    2. We are proud to announce that Bas Willemse is starting his PhD project at the computational personalization group at JADS; welcome Bas!
    3. We have updated some of our software downloads. Have a look around.


We are hiring!

We are looking for 2 motivated (and able) PhD students to join our lab on two great projects:

  1. First, we have a great project in collaboration with TiSEM; Its a project funded by the Tilburg Data Science Center investigating dynamic sequential learning approaches to combat customer churn. For a detailed descriptions see TiSEM-TSB-DynamicChurnModeling.
  2. Second, we have a project at JADS Den Bosch; within the Computational Personalization group (Theme: Data & Humans) we are looking for a candidate to further explore methods of causal inference in large datasets with applications in clinical practice. For a description see: JADS-CausalDataScience.

If you are interested (or have any questions), please send an email to m.c.kaptein@uvt.nl.

Visit MIT

Hi all,

I just had a great time visiting Prof. Dr. Dean Eckles at MIT; I attended ACM-EC (a great conference), and Dean and I discussed a lot of ongoing work (causality, habits, indirect inference, and much more). Looking forward to more collaborations. Here is a picture of Boston taken from the MIT Sloan building:

Note that we have also been doing a lot of software development:

  1. We presented UltimateSim (simulations of the Ultimatum game) during ACM-EC; see: https://github.com/Nth-iteration-labs/ultimatesim
  2. We are currently working on a total overhaul of StreamingBandit, making it easier to use, more scalable, etc. For progress see: https://github.com/Nth-iteration-labs/streamingbandit
  3. Finally, we are wrapping up a package for the online (row-by-row) estimation of hierarchical models. Hope to finalize the package soon, but see progress here: https://github.com/L-Ippel/SEMA_extended

That’s it for now; we wish all of you a great summer!

Site changes and physical lab


We did a few updates of our site; primarily updating the projects section. We are now fully emerged with the JADS institute (www.jads.nl) as one of the research labs; so do expect more projects and updates soon!

But, that means you should feel free to come and visit us!



Hi all,

We have a number of cool updates. First of all, we are happy to share the posters we will be presenting shortly at http://www.sigecom.org/ec17/index.html:

  1. Poster on Bootstrap Thompson Sampling (Eckles & Kaptein) – check it out here.
  2. Poster on Ultimatum Game Simulations (Kaptein) – check it out here.

Next, we are proud to present that our work on comparing operative vs. meta-judgmental measures for prediction of customer responses to persuasive messages was accepted at the Journal of Consumer Marketing (JCM). It will be in print soon, but you can find an author copy here.

Finally, I am proud to introduce two new PhD students: Xynthia Kavelaars will be working with Joris Mulder and Maurits Kaptein on a PhD project regarding Bayesian Adaptive Clinical trials, and Ylva Hendriks will be working on a joint project with Sebastiaan Peek and Prof. Inge Bongers on personalizing eHealth applications.



Picasso Pilot

Hi All,

We are piloting a new study; have a look at: https://survey.mnds.org/content/survey-picasso-2017

Any feedback is well-appreciated!


We are hiring!

Hi All,

We are hiring! I am involved in a number of PhD projects for which we are still looking for good candidates. First, check out the vacancies for the “Data science & Humans” research track at JADS:


Next, at Tilburg University I am involved in two exciting projects. Frist, we are looking for applicants for a project on adaptive Bayesian clinical trials:


Second, we are looking for candidates for a great position focussed on investigating the effects of e-health interventions:


Please do apply if you are interested!
