Applied Statistics

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

Start at the old train depot. After the run, we'll meet at Mile 20 for a drink! Run starts at 6:45 pm we will head toward Sterling tonight. Run at your own pace out and back. 2 mile runners turn around at Crestview Drive. 3 mile runners turn around at Tamarack Court. 3.5 & 4 - No cross streets in this stretch. You're on your own. :-) 5 mile runners - turn around at Sterling Blvd.

**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

Members of the public are invited to view the wonders of the universe through the telescopes of NOVAC volunteers at the Smithsonian's Udvar-Hazy Center in Chantilly, VA. You do not need to be a member of the club or own any astronomical equipment to attend. Telescopes will be provided by the Smithsonian and pre-approved members of the NOVAC. No other personal telescopes are permitted at the event. The event will take place on the bus parking lot of the museum. **Please park your vehicle at the south end of the main visitors lot and follow signs and red lights to the observing site. As a reminder, parking during the event is free.** Have a cosmic question? One of NOVAC's astronomers or museum staff will be happy to help you. As the sky gets dark, be prepared to enjoy the wonders of the night sky! Don't forget to dress warmly. Please check the weather forecast. For lighting, cover a flashlight in red cellophane (the darker the better). Bring along water to keep hydrated. Note: This outdoor event is weather-dependent and may be cancelled because of significant cloud cover or precipitation.
