Let’s completely rethink the notebook
2025-06-19 · 19:45
Jupyter notebooks have been around for a while now and are an approachable starting point for anyone interested to explore data and programming. It's done a lot of good, but it was never really designed to be 'the' Python notebook. It's always wanted to support multiple languages and this is reflected in many of the design decisions. And that makes you wonder, what could one do if we really did do just that? What if we ignored other languages and really only cared about Python and data tools? Would the notebook be different? The goal of this talk is to demonstrate this idea by talking about widgets, reactive Python, modern data tooling and also about the freedom to rethink your tools. There will also be demos. Lots. Of. Demos. |

Multi-Objective Optimization in Payment Routing
2025-06-19 · 18:30
Machine learning (ML) models in production often start with a single objective, such as maximizing conversion rate in the payment industry. However, real-world business contexts are often more nuanced where other aspects relevant to a transaction, such as transaction cost or fraud risk, come into play. These objectives can be inherently conflicting: while optimizing for authorization may drive more revenue, it could also lead to higher costs or increased risk exposure. Addressing such trade-offs necessitates the consideration of multi-objective optimization (MOO), while key information in the payment context plays a role in determining which objective should get more weight when considering the trade-off. In this talk we will share how we (Optimize ML team at Adyen) use the contextualized scalarization approach to improve our Intelligent Payment Routing product with a focus on conversion rate and transaction cost optimization. |

Working in Open Source - Probabl.ai and sklearn
2024-04-23 · 10:30
Creating and maintaining open-source libraries - Vincent Warmerdam About the event Outline:
About the speaker: Vincent works as a Research Advocate at Rasa where he collaborates with the research team to explain and understand conversational systems better. One of his activities is maintaining a youtube playlist that explains NLP algorithms over at “the algorithm whiteboard”. Before, he was a consultant working on production algorithms for a large range of companies. Vincent is a firm believer in open source and certainly doesn’t mind to evangelise from time to time. He has a blog about the slightly less obvious aspects in the world of data science over at https://koaning.io. He’s also working on a project that tries to help people get started over at https://calmcode.io. DataTalks.Club is the place to talk about data. Join our slack community! |
