Cold start is a critical bottleneck for marketplaces: new items lack behavioral signals and reviews, so ranking models under-expose them, delaying the very signals needed to rank them well.

GetYourGuide is a global online marketplace that helps travelers discover and book the best experiences. One of our core challenges is ensuring users always see the most relevant activities first—a task historically powered by an XGBoost-based ranking system.

GetYourGuide, a global marketplace for travel experiences, reached diminishing returns with its XGBoost-based ranking system. We switched to a Deep Learning pipeline in just nine months, maintaining high throughput and low latency.

In this presentation, I will discuss my transition from a Data Scientist to a management role, covering key managerial responsibilities, preparation tips, and the pros and cons of the switch.

In the realm of machine learning, the complexity of data pipelines often hinders rapid experimentation and iteration. This talk will introduce DDataflow, an innovative open-source tool, designed to facilitate end-to-end testing in ML pipelines by leveraging decentralized data sampling.

In this tutorial, we will learn the basis of MLflow. After introducing the library and the problem it solved we will implement an end-to-end machine learning lifecycle using MLflow.

Even if every data science work is special, a lot can be learned from similar problems solved in the past. In this talk, I will share some specific software design concepts that data scientists can use to build better data products.

I will introduce the concept of data unit tests and why they are important in the workflow of data scientists when building data products. In this talk, you will learn a new tool you can use to ensure the quality of the products you build.
