«Flexible Workflows with Metadata Routing API»
by Stefanie Senger, Open Source Software Engineer, PhD.

For all Data Science and Machine Learning Practitioners

This session will explore how metadata—such as sample weights or grouping information—can now be seamlessly passed through complex machine learning pipelines in scikit-learn. You’ll gain practical insights into how this powerful feature improves flexibility and fairness in model development.
One-hour thematic conversation in English.

«Time Series Forecasting»
By the scikit-learn core developers Olivier Grisel and Guillaume Lemaitre.

For experienced data scientists and ML Engineers - limited to 20 participants

This hands-on workshop will use both real world production and environmental data to illustrate how to deal with common data-quality problems. We will also use some specially crafted synthetic data to emphasize catastrophic pitfalls related to edge cases to gain deeper insights about our modeling choices and their limitations.

«Skrub: machine learning for dataframes»
by Guillaume Lemaitre, Chief ML Officer, PhD.

For experienced data scientists and ML Engineers

Machine-learning algorithms expect a numeric array with one row per observation. Typically, creating this table requires "wrangling" with Pandas or Polars (aggregations, selections, joins, ...), and to extract numeric features from structured data types such as datetimes. These transformations must be applied consistently when making predictions for unseen inputs, and choices must be informed by performance measured on a validation dataset, while preventing data leakage. This preprocessing is the most difficult and time-consuming part of many data-science projects.
One-hour thematic conversation in English.
