9:00 – 9:05 Opening
Moderator: Martin Szugat
9:05 – 9:45 Opening Keynote
Rethinking AI: Are We Climbing the Right Hill?
OpenAI took an amazing idea – Transformers – and sold it like a dream: ask AI. Now every company has AI-something to sell, and every country is gearing up for the AI race, turning international research into a form of treason.
But what if this madness could be our best chance to put aside the over-excitement about connectionism – without throwing away its amazing results – and think about the next class of problems worth solving? It’s time to rethink AI deeply – while we have the money – and start looking for damn good answers, not just good enough.

10:45 – 11:15 Accelerating Marketing Delivery: Axel Springer’s Journey to a Unified Next-Gen Automation Platform
Nils, Senior Data Engineer, and Justin, Senior Data Scientist, guide you through this Case Study featuring Axel Springer, known for media ventures like the Polish Onet. They illustrate how initially isolated predictive use cases evolved into a next-gen marketing automation platform that accelerates campaign delivery and drives subscriber growth. Justin explains the analytics behind the first ML use cases for better customer targeting, while Nils details critical data integrations that transformed these insights into a unified Customer Data Chip and seamless automation architecture. This session demonstrates the power of data products and serves as a blueprint for marketing enablement.
Speakers: Nils Paetsch & Justin Neumann
Human-in-the-loop: Practical Lessons for Building Comprehensive AI Systems
Machine learning models should not live in a vacuum. When a predictive model is exposed to the user to enrich a scientific or industrial workflow, incorporating human feedback is essential for the model to improve over time, overcome distribution shifts, and learn novel phenomena. We address the engineering challenges of building interactive active learning systems on a practical example of large-scale video analysis.
Speaker: Miha Garafolj
11:15 – 11:45 From Eye-Catching to Effective: Personalization That Actually Works in the Mol MOVE Loyalty Program at MOL Group
What happens when a data team faces a choice between cutting-edge and commercially effective? Working within Mol MOVE, a fuel retailer loyalty program covering 10 CEE countries, we tested both and share our key learnings from those two projects in this session: 1) a hyperpersonalization project, where we conducted microsegmentation, used GenAI to create data-driven personas, and use them to write personalized message to these microsegments 2) a discount optimization project, where we used a traditional AI approach to determine what would be the optimal discount level for every customer in that specific segment.
Speaker: Peter Szabolcs
11:45 – 11:50 Short Break
11:50 – 12:10 From Hypotheses to Conversions: Journey to First ML Models at Snaptrip
Explore Snaptrip’s path to their first ML Models. How we combined techniques like siamese networks, NLP and ensemble of multiple models in order to achieve conversion improvement on their website. We will describe how we tackled data drift in resource limited environment. You will walk away with description and real tips of practical ways to manage many experiments, and achieving balance between simple and complex approaches.
Speaker: Marcin Szymaniuk
Hijacking Attacks against DP Federated Split Learning
Split learning and differential privacy are technologies with growing potential to help with privacy-compliant advanced analytics on distributed datasets. This session will show applying a recent feature space hijacking attack (FSHA) to the learning process of a split neural network enhanced with differential privacy (DP), using a client-side off-the-shelf DP optimizer. It will show the results of the attack and discuss its implications.
Speaker: Grzegorz Gawron
12:10 – 12:30 Causal AI at Scale: Personalization of Push Notifications for Millions of PAYBACK Users
In high-scale mobile engagement, sending too many push notifications can alienate users, while too few can limit ROI. We built a causal AI system leveraging GCP to predict the optimal notification frequency for each user based on their behavior and characteristics. By estimating heterogeneous treatment effects through causal forests and validating through A/B testing, we developed a personalized frequency model that maximizes user interest and minimizes fatigue. This talk shares our journey from business constraint to scalable AI-driven solution that now serves millions of users daily

15:00 – 15:30 Coffee Break
15:30 – 16:30 Table Discussions
You are surrounded by fellow data scientists and there is no better place to discuss and share our common problems – off the record, and in a small group of max. 12 people. These are your people – they understand your situation. Often rated the best part of the event, sharing your problems with like-minded professionals is your path to answers, a little empathy, and a stronger professional network.
We will publish the topics and moderators of the roundtable discussions closer to the date.

16:35 – 16:50 From Reactive to Autonomous: Building Agentic AI at Feedly
Most AI products today are sophisticated tools; powerful, but passive. At Feedly, we’re transforming threat intelligence from a reactive discipline to a proactive partnership with AI. This talk traces our journey from RSS feeds to agentic AI workflows, sharing real lessons from building and deploying AI features used by thousands of security teams. I’ll demonstrate how we evolved from keyword matching to semantic AI Feeds, then added generative AI capabilities that analyze, summarize, and create intelligence reports. More importantly, I’ll share our vision for the next frontier: agentic AI that acts as a trusted security colleague; continuously hunting threats, understanding organizational context, and taking autonomous actions.
Speaker: Farah Ayadi
Advanced Prompt Engineering and Beyond: Ingredients Needed for Working LLM Based Products
We start with examples of advanced prompt engineering. Then we will show limitations of various approaches and iterate through retrieval techniques and verification. We’ll dive into Hyde and Colbertv2 for ReRank and better retrieval, and Chain of Thought for reasoning. Learn how LLMs can act as judges, balancing fairness and precision. We will also explore when it makes sense to use PEFT. We’ll tackle challenges like sneaky user behavior and testing non-deterministic outputs.

17:10 – 17:25 How Not to Get Burned: Security Lessons from Real-World LLM Deployments
Many LLM projects fail to deliver secure, reliable results due to overlooked risks like data leaks, prompt injection, and poor governance. This session unpacks common security pitfalls through 10 real-world cases from finance to healthcare—then offers hands-on strategies for safer LLM design, deployment, and oversight. Learn how to align innovation with safety, compliance, and trust at every stage of the AI lifecycle.
