**Pre-registration is REQUIRED. RSVP here - [https://hubs.li/Q046VS--0](https://hubs.li/Q046VS--0)** **Speaker:** Michael Novack, Solutions Architect at AIceberg **Topic title:** "Trust What You Can Trace: Making Agentic AI Explainable, Secure, and Enterprise-Ready" As enterprises adopt increasingly powerful AI systems, one critical challenge remains: understanding how and why these systems make decisions. Many modern models - especially large language models - operate as opaque “black boxes,” making transparency, compliance, and trust difficult to achieve. *This webinar introduces the AI Explainability Scorecard, a practical framework for evaluating the transparency of AI systems based on criteria such as faithfulness, consistency, accessibility, and comprehensibility*. Attendees will learn how different model architectures - from K-Nearest Neighbors to neural networks and transformers - vary dramatically in explainability and risk. **The session will also explore real-world techniques for improving visibility into complex models, including surrogate monitoring approaches that map AI behavior to comparable examples.** These methods help organizations build observable, auditable AI systems without sacrificing performance or scalability. By the end of this session, attendees will understand how to move beyond black-box AI toward transparent, accountable, and secure AI deployment - a critical step for enterprises scaling agentic AI in high-stakes environments. You will learn: **\- Why Explainability Is the Foundation of Trustworthy AI** *Learn why transparency isn’t just a technical preference - it’s becoming a legal, ethical, and operational requirement for enterprise AI systems.* **\- The AI Explainability Scorecard Framework** *Understand the five key criteria - faithfulness, comprehensibility, consistency, accessibility, and optimization clarity - for evaluating how explainable an AI model truly is.* **\- How Different AI Models Compare in Transparency** *Discover why some models are inherently interpretable while others require advanced methods to understand their behavior.* **\- Practical Methods for Making Black\-Box AI Observable** *Explore modern techniques - including surrogate monitoring models - that help organizations understand and audit large language models at scale.* 🔗 Stay Connected * **Learn:** Free talks and trainings on the [Ai+ Training platform](https://aiplus.training/). * **Read:** The latest in AI research on the [ODSC Blog](https://opendatascience.com/). * **Chat:** Join the conversation in our [Slack Channel](https://www.google.com/search?q=https://odsc.com/slack). * **Community:** Review our [Code of Conduct](https://odsc.com/code-of-conduct/).

Please join us for our next **Friday gathering** on **April 10, 2026** for an evening of warm fellowship and insightful discussion. We'll start at **7:00 pm** with **refreshments** at the **Alexandria Bahá’í Center**. The discussion will begin at 7:30 p.m. **Education as an Act of Hope - Constructive Response to Suppression.** This is a story about what happens when ordinary people respond to injustice not with despair, but with determination to build something better. Join us for an inspiring evening with **Kamran Farid**, co-founder of the Bahá'í Institute for Higher Education (BIHE), as he shares a powerful story of resilience, courage, and hope. **About the Discussion:** In 1987, when Bahá'í students and professors were expelled from all Iranian universities simply because of their faith, a group of educators made a bold choice: they would create their own university. For nearly four decades, BIHE has operated underground in Iran, offering degree programs to students denied the fundamental right to education. Kamran will explore a compelling question: *How does access to education sustain hope in communities facing systematic oppression—and what happens when that access is denied?* **About Our Speaker:** Kamran Farid holds degrees in electronics and communication engineering. As a BIHE faculty member and administrator, he was arrested in 2011 and imprisoned for five years—his "crime" was teaching. Since his release in 2016, he continues to support BIHE's mission as a consultant, ensuring new generations can pursue their dreams of higher education despite ongoing persecution. **All are welcome.** No background knowledge required—just bring your curiosity and an open heart.

Adam Sandman will be showing how you can use Kiro together with an MCP server to pull software requirements, designs and tasks from a project management repository (Spira) using an MCP server. From there we can use the power of agentic AI to create an MVP app, deploy and test it.

Hi everyone - apologies but I'm pushing the planned March 11 event back to April 8. I'm hoping a large group can make it out that night, so am upping the limit to 12. We had a wave of late cancellations for March and which isn't fair to Verre, they are giving up other business to accommodate us and the group got too small to be viable for them. Please only RSVP if you are fairly certain you can make it, as this late change of plans isn't fair to the group or the host restaurant, thanks. **EVENT STARTS AT 6PM. PLEASE BE PROMPT.** 🍷What is blind wine tasting?🍷 You use your sense of smell, sight, and taste to try to deduce which variety (grape) is in the glass. This group is very experience-diverse and we welcome both wine newbies and wine pros (and everyone in between). Verre will pour us two wine flights, one white and one red (3 of each, so a total of 6 wine samples) and we will discuss what we are tasting to try to solve the mystery together. After each flight is a big reveal where we find out just how right (or wrong!) we were. Diana will let us know the possible wines we are going on grid tonight. Please arrive at **6:00pm**. The white wine flight is served around 6:10 and the red flight around 6:50. The cost will be about $15 per flight, depending on what is poured for us. Food and other wine will be available for purchase as well. 🍷RSVPs: Verre has a limited amount of table space and is reserving much of that space for our group. Out of consideration to the business, the event hosts, and anyone on the wait list, **please edit your RSVP as soon as possible if your plans change** and you can no longer attend the event, **even if you are on the wait list**. 🍷Transportation: * METRO: Verre Wine Bar is walking distance from Courthouse metro. * CAR: Metered street parking and paid garage parking are available in the area. Hope to see you there! \~Pete Waitlisted Friends! \*PLEASE\* keep an eye on this page and your messages especially close to the day of the event. Thanks!

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
