At 21 april 2023, we held an epic hackathon where 10 teams from KPN, Rabobank, DPG, Athora, ANWB, UWV, Lifetri, and Eneco joined forces to rescue our beloved Princess Peach from the claws of Bowser. It was a fierce battle, but in the end, only one team emerged victorious. And who was that, you may […]

At Cmotions we’ve always had a lot of discussion amongst colleagues whether or not to balance our datasets when building a predictive model. Everyone has their own personal preference and way of working, but which approach is “the best”? We simply didn’t know until we stumbled upon this paper written by Jacques Wainer and Rodrigo […]

What did we learn from joining Kaggle’s Commonlit Readability prize? Well, next to having a lot of fun, it definitely helped us to explore the text analytics landscape even further. You can read our whole story in this article

Almost every day we go online we encounter recommender systems; if you are listening to your favorite song on Spotify, binge watching a TV show on Netflix or buying a new laptop on Amazon. Although we all know these recommendation engines exist, it is less known what algorithms lie behind such recommendations. To get a better understanding of the algorithms used in recommender systems we decided to build a recommender ourselves! With COVID-19 making us more housebound than ever, a topic for our recommendation engine was quickly found; we decided to build a book recommender using Python. Although there are ready-to-use packages to build recommender systems (such as Surprise) we decided to built or own recommendation system. We did this because our goal was to understand how a recommendation engine works rather than just have a book recommender. Moreover, we wanted to be able to control the specifications of the variables used in our engine and wanted to avoid the black box. In this notebook we explain step-by-step how we built our recommendation engine.

Deze week is er in de haven van Rotterdam een flinke partij Mexicaans bier onderschept. Om verdere verspreiding van deze verslavende drank te voorkomen, heeft de regering voor de komende weken strenge beperkingen gesteld op alle goederen die vanuit risicogebieden geïmporteerd worden. Dit betekent dat ook de import van tortillachips, avocado’s en jalapenopepers de komende […]

Al jarenlang staan de kranten er vol van: Nederland dreigt een nachostaat te worden. Het gebruik van tortillachips in het uitgaansleven is eerder een regel dan uitzondering en er vaart geen vrachtschip uit Zuid-Amerika de haven binnen zonder verstopte pakketjes jalapeño pepers en crème fraîche in bananendozen. In schimmige Nederlandse kelders worden avocado’s versneden tot […]

Op vrijdag 10 maart jl. heeft de tweede “The Analytics Lab Hackathon” plaatsgevonden, de opdracht was dit keer om de zetelverdeling te voorspellen van de Tweede Kamer na de verkiezingen van 15 maart. Dankzij de serieuze, sportieve en ook humoristische inzet van onze deelnemende teams is het weer een zeer leuke dag geweest, waarbij iedereen […]
