The Lineup for the evening
**Talk 1: Text2SQL in the Wild — Agentic Workflows & Semantic Models on Customer Data**
**Abstract**: Translating a business user's natural language question into a reliable SQL query has huge value for business analysts, but doing it accurately at scale, on messy enterprise data, for complex queries, is incredibly difficult. This talk walks through a production Text2SQL system built on four pillars: semantic models built on customer data, RAG-based semantic search, an agentic verification and correction loop for building the SQL, and an evaluation framework for the entire process.
Raw schema information is not enough for text2sql to work. Rather, thorough documentation including business metrics, synonyms, and qualified example queries, are required. We'll cover how to automate this documentation pipeline by mining query logs, generating descriptions with LLMs, and organizing everything into a knowledge graph and vector search index. From there, we'll dive into the agentic flow that takes a user question and iteratively generates, validates, and fixes SQL against a live database. The agentic framework analyses syntax errors and execution results to help it fix the SQL. Participants will leave with practical takeaways on RAG architecture for structured data, agentic retry patterns, and how to think about evaluation for Text2SQL systems in production.
**Speaker**: Oren Matar
**Bio**: Oren Matar is a principal data scientist and algorithms developer, with a background in social sciences and Bayesian methods. He specializes in NLP and time series forecasting, as well as agentic methods for data retrieval and processing.
**Talk 2: Interpreting and Communicating Statistical Models**
**Abstract**: Extracting actionable insights from complex statistical models remains a challenge, as raw coefficients are often uninterpretable due to nonlinearity, interactions, or hierarchical structures. This talk introduces a unified framework for model interpretation based on the principles of the Marginal Effects project ([https://marginaleffects.com/](https://marginaleffects.com/)). We move away from internal model parameters toward quantities of interest, such as marginal effects and adjusted predictions that translate statistical output into the "natural language" of the data.
We will demonstrate these concepts in Python using the Bambi interpret module, showcasing a seamless workflow for interpreting Bayesian models built on PyMC. The audience will learn how to use the four primary interpretative pillars: Predictions, Comparisons, Slopes, and Marginal Means to compute average marginal effects and visualize conditional relationships. By the end of this session, you will be equipped to turn sophisticated GLMs and multi-level models into clear, rigorous narratives that are easily communicated to stakeholders.
**Speaker**: Juan Orduz
**Bio**: Juan is a Mathematician (Ph.D. Humboldt Universität zu Berlin) and Principal Data Scientist at PyMC Labs. He is interested in interdisciplinary applications of mathematical methods. In particular, time series analysis, Bayesian methods, and causal inference.
**Lightning talks**
There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks.
Kindly let us know if you would like to present something :)

Theory Meets Practice #4: Explainable Scientific Discovery with AI Memory
**⚠️ IMPORTANT: REGISTRATION MANDATORY ⚠️**
Registration on **Luma** is **REQUIRED** to attend this event. **Link: https://luma.com/1sre8dy7?utm_source=meetup**
Your registration is subject to host approval. You must complete the registration process on lu.ma to receive the full event location details and confirmation of your attendance.
**Please note: Without approved registration on Luma, you will NOT be able to access the event location or attend.**
We are excited to host a **BLISS x dida workshop** featuring **Lazar Obradović (Lead Data Scientist @ cognee.ai)**, who will guide us through an interactive session on Agentic AI.
Title: Explainable Scientific Discovery with AI Memory:
Hypothesis Generation and Validation with Cognee and Bayer
📅 Date: 27.05.2026
🕕 Time: 18:00
📍 Location: TU Berlin Marchstrasse 23 [Room 0.011]
The session will last around 2 hours, followed by a networking session with dida and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop!
**Abstract: Building "AI scientist"** systems that can reliably generate and evaluate research ideas remains effectively an open problem. While LLMs make hypothesis generation cheap, current systems still struggle to connect evidence across papers, domains, and mechanisms in a structured and reusable way. Evaluation is equally difficult, often relying on opaque “LLM-as-a-judge” methods that are hard to interpret or reproduce. We use Cognee to ingest scientific literature and construct a graph-based representation of papers, claims, and entities with associated vector embeddings. We then use this structure to select and organize the context used for hypothesis generation. Candidate hypotheses are evaluated using explicit graph- and vector-based metrics grounded in the underlying corpus. Initial evaluations by Bayer across targeted biomedical domains demonstrated that graph-based AI memory can reliably support scientific hypothesis generation and validation.
**⚡ FINAL REMINDER ⚡**
**You MUST register and be approved on Luma to attend. The event location will only be visible after your registration is confirmed by the host. Link: https://luma.com/1sre8dy7?utm_source=meetup**

The Buddha Wears Prada
A dark stand-up work-in-progress English comedy hour about Sofia May's experience as a former assistant of Buddhist cult leader
A dark stand-up work-in-progress comedy hour about Sofia May's experience as a former member of a Buddhist cult's inner circle, working as the assistant of a very chic, diabolical, female cult leader.
After living the life of a religious Buddhist zealot in a secluded community deep into the Colorado Rocky Mountains for years, Sofia hit the road and blew the whistle. It isn't a famous cult yet, but through exposés, podcasts and general trash-talking, it will be in a year.
What's more, now a self-proclaimed "Buddhaphobe", she intends to ruin your relationship with Buddhism too.

Standup Comedy with Maya Upchurch - Rotten Apple
**“Rotten Apple” is Maya Upchurch’s ranty, angry, morally-corrupt debut stand-up hour. Inspired by the likes of Bill Hicks, Bill Burr and Joan Rivers, she's a high-energy force of Gen-Z nature who lacks the ability to speak of anything other than exactly what's on her mind. Based out of Berlin, she's got a truckload of tales from the European capital of hedonism and her Polish/American background gives her a unique and interesting perspective on what it’s like to have two strong passports and a generally good life.**
**While Maya most certainly will make fun of everyone and everything on her path, her favorite person to roast is undoubtedly herself. Bringing light to her time-wasting habits, irrational anxieties, and dependence on technology, she believes that "punching-up" is best done when it’s an upper-cut to yourself.**
**Maya started doing standup in 2020, shortly after her first set there was lockdown because China was scared of her power. Since then she's done shows all around Europe, was a featured in The New York Times, performed with Don't Tell Comedy, opened for the likes of Todd Barry, Ashley Gavin, April Macie and did all sorts of other really cool and exciting stuff.**

Ensuring Software Quality in the world of AI Developers - Matt Eland
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod.

Psychic Development Series II - Pueo Group
Private Group. Closed to the Public
Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy.
In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected.
The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve.
I look forward to sharing and discovering with you. - Cynthia
