**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/27ja5gwl Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity. ​ ​**​Agenda:** ​​6:00 - 6:30 PM - Welcome and mingle 6:30- 6:45 PM - Introductions 6:45 - 7:30 PM - Talk 7:30 - 8:00 PM - Wrap up **​​Description:** ​If you have ever shipped a model, watched your metrics improve, and later learned from your users that something was wrong, the metrics were always wrong. You just didn’t know it yet. An evaluation consists of three components, a benchmark, a scorer, and a claim about what a score represents. Each component has its own weaknesses. Benchmarks can suffer from narrow coverage, contamination, or saturation. Scorers are often chosen for ease of automation or computation rather than for their alignment with user outcomes. And the claim connecting a score to reality is rarely made explicit. These gaps compound across the model development lifecycle. When metrics improve, teams treat that as a signal and optimize directly against it, which is how a measurement problem becomes a model problem. This talk maps where evaluations can go wrong, considers counterarguments, and ends with practical advice for building better ones. **​Speaker Bio:** ​Mary is a Senior Applied Scientist at Relativity, tackling data science challenges in the e-discovery and legal tech space. She is also an organizer for Women and Gender eXpansive Coders DC (formerly Women Who Code DC), fostering a community dedicated to empowering women and nonbinary individuals to excel in their careers. Mary's experience spans various domains. She has developed data science solutions related to job search and career progression at Teal, cybersecurity challenges at LiveAction Software, and commercial and government consulting at Mosaic Data Science. Before venturing into the field of data science, Mary conducted and published research pertaining to the cellular and molecular mechanisms underlying neurodevelopment at the National Institutes of Health. In other words, she has dissected and imaged a lot of fruit fly brains. She holds a M.S. in Data Science from The George Washington University and a B.A. in Biological Sciences from Cornell University

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Artemis II and Beyond,”** on how the recent space mission fits into long-term plans for the Moon, with Michael J. Neufeld, retired senior curator for the Space History Department of the Smithsonian’s National Air and Space Museum. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-artemis-ii-and-beyond](https://events.ticketleap.com/tickets/profsandpints/dc-artemis-ii-and-beyond) .] NASA’s recent, spectacular Artemis II mission is a sign that the United States is serious about sending humans to the Moon again. Gain an understanding of how Artemis II fits in both past and planned lunar missions with historian Michael Neufeld, who was lead curator of the Smithsonian’s Destination Moon exhibit. He has taught at Johns Hopkins, Colgate, and other universities, and is the author or editor of nine books dealing with the history of technology. He’ll start by looking at the aftermath of the Apollo program of a half century ago and why it ended only four years after its first lunar mission. He’ll consider why no lasting lunar programs emerged from major announcements by two presidents, George H.W. Bush and George W. Bush, that astronauts would be going back to the Moon and on to Mars. His vividly illustrated lecture will then explore how Artemis is a product of a human spaceflight program that has changed dramatically over the past 50 years. We’ll look at how collaboration with Europe, Canada and Japan became integral to the shuttle and International Space Station programs, and how the rise of new commercial space companies such as SpaceX has enabled NASA to buy both space services and space craft. Both international and commercial partners are involved in the latest Moon efforts, with SpaceX and Blue Origin expected to supply the landers to take astronauts down to a planned base on the Moon’s South Pole. How soon will any of this happen? Probably not as quickly as NASA says, but the specter of a Chinese landing on the Moon by 2030 is one obvious reason to keep things moving along. We’ll look at the sustainability of the Artemis space program for at least the next decade or so. You’ll emerge from the talk with no doubt that exciting days are ahead for space fans. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: The Artemis II mission launch (NASA photo).
