Onehot is a community for people passionate about data science. We are centered in Utrecht, the Netherlands.

We want to build an inclusive community where everyone is welcome to share and learn. Whether you are a practicioner or student, analyst or engineer; please feel free to join us in this endeavour!

Currently we are organising a series of five meet-ups. Our dream is to organise a full-fledged conference one day.

The name of our community is a reference to one-hot encoding.

Get in touch

Please reach out to us if you have questions or suggestions, would like to speak at one of our events, or are willing to sponsor us. Same goes if you just want to say hi: we love hearing from you!
