**Welcome to DSF Sandbox Sessions!** Top tech talks and masterclasses from the best in the industry. Every month, and completely free. The catch? There isn’t one. Just a monthly dose of epic content to power up your data passion! **Event details** 📆 **Date:** Tuesday 14th April 2026 ⏰ **Time:** 6:00 – 9:30 PM BST 💡 **Topic:** **Signals, Systems, and Scams: Deconstructing the Future of Financial Intelligence** 🗣️ **Speakers:** Kristjan Erik Liive, Volodymyr Panov, Baran Koseoglu, Zoltan Szopory, Vera Shishkina, Aaron Wilson, Mohammed Topiwalla [Sign up for this event by clicking here!](https://datasciencefestival.com/session/wise-sandbox-session/) As global financial platforms evolve, the “Trust Gap” becomes an engineering challenge. Scaling a product to millions of users requires more than just better models—it requires a fundamental shift from manual heuristics to automated, high-fidelity intelligence. Join Wise for an exclusive Sandbox Session designed for senior data scientists and engineers. We’re moving beyond the basics of model training to explore the “Last Mile” of production ML: the infrastructure of compliance, the democratisation of optimization, and the transition to foundational representation learning. Through three practitioner-led deep dives and a collaborative product-data science panel, we will deconstruct how Wise builds resilient financial infrastructure where performance and safety are never a zero-sum game. What we’ll explore: • The GenAI Reality Check: Moving LLM automations from “cool demo” to “compliant production” in highly regulated spaces. • Decoupling Optimization: How we built “Threshold UI” to empower non-experts to tune model performance across hundreds of cohorts without a single code change. • Beyond Velocity: Replacing hand-crafted features with User Event Transformers to capture the deep behavioral context that traditional tabular data misses. • The Co-Design Philosophy: Why the future of fraud prevention isn’t just a better algorithm, but a tighter feedback loop between Product and Data Science. Food, drinks, and networking with fellow practitioners will follow throughout the evening. Check out the full session details below! **Please note: Due to high demand and limited capacity, tickets for this event will be allocated via a random ballot.

We will share examples, discuss architectures and challenges of building LLM-based automations in compliance-heavy space. We will also present our vision and key opportunity areas in further augmentation and automation. **Key takeaways:** Practical examples of scoping and implementing LLM-based solutions. **Talk 2: On the Threshold of Greatness: Democratizing Model Optimization at Wise** **Speakers:** Baran Köseoğlu, Lead Data Scientist & Zoltán Szopory, Staff Software Engineer. **Abstract:** This session will talk about machine learning model threshold optimization across hundreds of customer cohorts. Traditionally, optimizing these thresholds has been a complex, time-consuming task, often relegated to highly technical experts. At Wise, we faced the challenge of managing diverse customer segments, each with unique risk profiles and compliance mandates and as a solution we developed Threshold UI we will talk about more in the session. **Key takeaways:** Boost your machine learning model performance without changing any configuration in your training pipeline. **Talk 3: More Than Meets the Eye: Transforming User Events into Deep Context** **Speaker:** Vera Shishkina, Staff Data Scientist. **Abstract:** Moving from purely manual feature engineering to representation learning. This session covers the technical POC of a User Events Transformer – a foundational model designed to produce customer embeddings that augment traditional tabular features. We will discuss the proposed architecture, the challenges of building temporal data pipelines, and our vision for using these embeddings to boost performance in domains like scam prediction. **Key takeaways:** How learned embeddings provide deep context that traditional “velocity” features often miss. **Talk 4: Panel Discussion – Mind & Machine: How Product and DS Co-Design the Future of Trust** **Panellists:** Aaron Wilson, Fraud and Victim Prevention Product Lead & Mohammed Topiwalla, Fraud and Victim Prevention Data Science Lead. **Abstract:** Fireside chat to understand how DS and Product work hand in hand to keep wise safe. **Key takeaways:** How do you find the middle ground between business growth and risk precision? What is the future of DS in fraud prevention? **Schedule:** **6:00 PM** – Doors open – networking with food and refreshments **6:45 PM** – Intro **6:50 PM** – Talk 1 (20 minutes + 5 minute Q&A) **7:15 PM** – Talk 2 (20 minutes + 5 minute Q&A) **7:40 PM** – Comfort break **7:50 PM** – Talk 3 (20 minutes + 5 minute Q&A) **8:15 PM** – Talk 4 (30 minutes) **8:45 PM** – Networking with refreshments **9:30 PM** – Event close **Registering for the event:** Click the 'Sign up here!' button on the specific event page following the link below.

We are trying something new at Socrates Cafe Dublin. We are doing **trilogies** \- three back\-to\-back monthly topics that connect to tell a story\. Our next trilogy will be around the mystery of human flourishing\. For our first in the series we are going to ask: *What is beauty?* Then in May: *What role does 'home' play in our well-being?* Finally, in June, *what roles do nature and nurture play in our well-being?* We’ve all made the exclamation: “now, that is beautiful!” And life seems better, richer for it. What do we mean by ‘beauty’? What qualities does something require in order to be classified in such a way? What things can be given such label? Are there things that do not deserve to be called beautiful? Is beauty restricted to physicality? Is beauty merely subjective or does it have an objective framework? Is it a matter of the feminine side of life? Is it something internal or external? Come along next Tuesday evening at the lovely Third Space Cafe Smithfield for a facilitated discussion about beauty. Newcomers are welcome. NOTE: we ask for a 3 Euro donation to cover expenses. Pay on the evening by coin or Revolut. Socrates Cafe: a space where ideas and dialogue can flourish.

Welcome to the April'26 edition of PyData Ireland. This meetup is in association with Quantum Black, AI by McKinsey. Agenda for the day: * 17:30 – Arrival * 18:00 – Start of talks (Details below) * *Jitendra Gundaniya*: **Building Agentic GenAI Pipelines with Kedro Builder (Beginner-Friendly)** * *Dmitry Sorokin*: **Let AI Agents Manage Your ML & Data Pipelines** * 19:30 – Networking \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Talk 1:** Building Agentic GenAI Pipelines with Kedro Builder (Beginner Friendly) **Speaker Name and Designation:** Jitendra Gundaniya, Senior Software Engineer at QuantumBlack, AI by McKinsey **Speaker LinkedIn:** [https://www.linkedin.com/in/jitu11](https://www.linkedin.com/in/jitu11) **Talk Description:** This talk shows how Kedro Builder, a visual drag-and-drop tool, can lower that barrier. We'll walk through building a simple agentic pipeline visually dragging LLM context nodes, connecting prompts and tools, and exporting a working Kedro project, all without writing boilerplate by hand. Think of it as a learning ramp: see the pipeline structure first, then dive into the code. **Key Takeaways:** * How a visual builder can make agentic pipeline patterns (LLM + prompts + tools → agent → output) more approachable for beginners * What `llm_context_node` is and how it simplifies GenAI pipeline creation in Kedro * A live walkthrough of building and exporting a GenAI pipeline using Kedro Builder * Where the visual approach helps (pipeline scaffolding, boilerplate) and where you still need code (agent logic, output schemas) \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Talk 2:** Let AI Agents Manage Your ML & Data Pipelines **Speaker Name and Designation:** Dmitry Sorokin, Senior Machine Learning Engineer II at QuantumBlack, AI by McKinsey **Speaker LinkedIn:** [https://www.linkedin.com/in/dmd40in/](https://www.linkedin.com/in/dmd40in/) **Talk Description:** This talk explores how traditional data & ML pipeline frameworks can be wrapped with an MCP server, enabling AI agents (e.g. LangGraph, Claude Code) to connect and manage pipelines programmatically. We’ll look at how this approach combines the deterministic nature of production data & ML workflows with the flexibility and reasoning capabilities of modern AI agents. **Key Takeaways:** * How to expose data & ML pipelines through an MCP server * How AI agents can orchestrate and manage existing workflows * A practical pattern for combining deterministic pipelines with agentic flexibility
