Free-floating carsharing systems struggle to balance vehicle supply and demand, which often results in inefficient fleet distribution and reduced vehicle utilization. This talk explores how data scraping can be used to model vehicle demand and user behavior, enabling targeted incentives to encourage self-balancing vehicle flows.

Using information scraped from a major mobility provider over multiple months, the presentation provides spatiotemporal analyses and machine learning results to determine whether it's practically possible to offer low-friction discounts that lead to improved fleet balance.

In aviation, search isn’t simple—people use abbreviations, slang, and technical terms that make exact matching tricky. We started with just Postgres, aiming for something that worked. Over time, we upgraded: semantic embeddings, reranking. We tackled filter complexity, slow index builds, and embedding updates and much more. Along the way, we learned a lot about making AI search fast, accurate, and actually usable for our users. It’s been a journey—full of turbulence, but worth the landing.

If you’re tired of LLM demos that don’t deliver, this talk is your blueprint for building agents that actually work.

In this tutorial, you will play several games that can be used to teach machine learning concepts. Each game can be played in big and small groups. Some involve hands- on material such as cards, some others involve electronic app. All games contain one or more concepts from Machine Learning.

As an outcome, you will take away multiple ideas that make complex topics more understandable – and enjoyable. By doing so, we would like to demonstrate that Machine Learning does not require computers, but the core ideas can be exemplified in a clear and memorable way without. We also would like to demonstrate that gamification is not limited to online quiz questions, but offers ways for learners to bond.

We will bring a set of carefully selected games that have been proven in a big classroom setting and contain useful abstractions of linear models, decision trees, LLMs and several other Machine Learning concepts. We also believe that it is probably fun to participate in this tutorial.

Small Language Models (SLMs) offer an efficient and cost-effective alternative to LLMs—especially when latency, privacy, inference costs or deployment constraints matter. However, training them typically requires large labeled datasets and is time-consuming, even if it isn't your first rodeo.

This talk presents an end-to-end approach for curating high-quality synthetic data using LLMs to train domain-specific SLMs. Using a real-world use case, we’ll demonstrate how to reduce manual labeling time, cut costs, and maintain performance—making SLMs viable for production applications.

Whether you are a seasoned Machine Learning Engineer or a person just getting starting with building AI features, you will come away with the inspiration to build more performant, secure and environmentally-friendly AI systems.
