For each of the 3B ads we display every day, we need to dynamically choose around 4 products to put in the banner. Not only the choice of algorithm has to be driven by the size of the catalog, but also by a time constraint: the system has less than 100ms to make a recommendation. These two constraints make quite challenging the design of algorithms that can take into account the others complexities of the problem such as the heterogeneity of the catalogs or the cold start problem induced by the fact that products come and leave very frequently. On top of that, the system interacts with a human user across several displays, which requires to introduce either some diversity or some structure across recommendations. Read more about us here:

We meet each month to present an inspiring talk or organize a data-hacking session.


The mission of the project is to share knowledge how to use machine learning in real life. Start to think how to get a business value for a given context. There’s a big gap, especially in Europe, how people think in the tech world. Usually, it’s more about technology or theory, and less about value and benefits. And one more gap is increasing demand for people who understand machine learning. DataWorkshop try to solve these problems. The idea is simple. Focus more on practical examples, less on theory (don’t try to cover all topics, only the most important). Explain by examples, not by theoretical formulas. Motivate to think and “feel” how to solve a problem, instead of memorizing some formulas or names (algorithms, models and so on). DataWorkshop accomplishes its goals through workshops, conferences, and courses.

DataWorkshop helps programmer became a programmer 2.0.
