NOTE: A valid photo ID is required by building security. You MUST use your full real names on your meetup profile, otherwise you will NOT make it on the guest list!

Tickets are assigned through a lottery draw initially. Waitlist places are assigned manually. We can only admit you if you use your full real names on your meetup profile.

If your RSVP status says "You're going" you will be able to get in. No further confirmation required. You will NOT need to show your RSVP confirmation when signing in.

If you can no longer make it, please unRSVP as soon as you know so we can assign your place to someone on the waiting list.



As always, there'll be free food & drinks, generously provided by our host, AHL.

We are issuing tickets via a lottery - if you want to be in with a chance of a place - sign up for the waitlist! The lottery will be run approx 1 week before the meetup, and we will re-run the lottery to fill any spaces that free up or use the waitlist towards the time of the event.

Main Talks:

Gabriel Straub and Douglas Penna on “It’s bigger on the inside” - A BBC powered by Connected Data

Abstract: We will be talking about how to use a machine learning based focus product to lead a wider organisational transformation towards more personalised user experiences. The talk will be in two parts: initially Gabriel will introduce the business challenge and our approach and then Douglas will talk a bit more about the technology and algorithms used.

Dean Allsopp on Hermeneutic Investigations: What Can Interpretable Machine Learning Do Today?

What can Interpretable ML tools tell us about models and predictions? There has been plenty of discussion over the last few years about the need to not just make predictions, but provide ways to communicate how models and predictions work. What tools are available now and how can they help?

Lightning Talks:

Pav Andriychenko on: Tidy up your Jupyter Notebooks: source control made easy; spot unused imports and PEP-8 your notebook code!

Nathalie Skrzypek on: AB Testing at Photobox
The presentation will provide an overview of AB testing; it's definition, the logic, the stats, and it's application and implementation at Photobox.


Doors open at 6.30pm (get there early as you have to sign-in via AHL's security), talks start at 7 pm, drinks from 9 pm in the bar. We normally have >200 folks in the room so there's plenty of people to discuss data science questions with!

Please unRSVP in good time if you realize you can't make it. We're limited by building security on the number of attendees, so please free up your place for your fellow community members!
