Machine Learning Chalk Talk | |
David Hogg et. al | |
Event Type: Special Seminar | |
Time: 11:00 AM - 12:15 PM | |
Location: 726 Broadway, 940, CCPP Seminar | |
Abstract: MLCT is a weekly seminar hosted by the Physics department where anyone—students, postdocs, faculty—can present a 45-minute-ish lecture or discussion on machine learning or statistical inference. The setting is informal, chalkboard-focused (with optional slides), and interruptions are encouraged. Topics can range from rough ideas to finished research, with the assumption that the audience is at the level of a graduate student who has some knowledge of how typical ML methods work. To see a weekly schedule of seminars, see https://dwh.gg/MLCT For those wondering, What is the Style of the Talk? A useful talk should be research-level-oriented, with a strong emphasis on explicit mathematical explanations and interpretations of machine learning methods. The focus should be on methodological insights rather than just presenting results, with a particular interest in understanding why methods succeed or fail. If there are tutorials, they should go beyond basic introductions, offering deeper, pedagogical insights. |
Galactic Archaeology in the Gaia Era | |
Keith Hawkins, University of Texas at Austin | |
Event Type: Astro Seminar | |
Time: 2:00 PM - 3:15 PM | |
Location: 726 Broadway, 940, CCPP Seminar | |
Abstract: Our universe it made up of many billions of galaxies, yet we are still trying to figure out how they form, evolve, and assemble themselves over cosmic. This question of galaxy formation and assembly is among the most fundamental in modern astronomy yet the answer still eludes us to this day. The Milky Way is an optimal laboratory for answering the questions of galaxy formation and assembly because it is one of the only systems to date where we can obtain detailed and precise data on the positions motions and chemical composition for billions of individual stars. Using our Galaxy as a sandbox for exploring galaxy formation and assembly is the essence of Galactic archaeology. In this talk, I will discuss the work my group has done on uncovering the structure and assembly history of our Galaxy using large-scale astronomical surveys such as the Gaia mission. |
