SUMMARY:Other:Indoor Nature Play Pop Up
DESCRIPTION:Bring your imagination to life at our Riverscapes Small World Nature Play Pop-ups in Greenhouse 3\, part of MBGNA's Winter Exhibit. This drop-in\, hosted experience invites families with children ages 3–9 to explore\, create\, and get delightfully messy in hands-on nature play. Perfect for curious minds and tiny hands\, these pop-ups offer a fun and interactive way to connect with the natural world. Come prepared for some playful creativity\, and maybe a little mess!  Free\, no registration required.\n\nWednesdays 3-5pm\, Dec 11\, 18\, Jan 8\, 15\nFridays\, 10am-12pm\, Dec 13\, 20\, Jan 3\, 10

SUMMARY:Careers / Jobs:International Students Career Series: How to Navigate Small Talk
DESCRIPTION:In the United States\, many people participate in what is called \"small talk\"\, where you make conversation with strangers or acquaintances about non-controversial topics\, such as the weather\, sports\, or popular television shows. “Small talk” is one of the ways in American culture to chat about harmless topics in order to establish a connection and start to build a friendship. For example\, while waiting for an interview\, in line at a M-Den\, or in an elevator on campus\, don’t be startled if a stranger says something to you like\, “Did you watch the FootballGame last night? What a game!” They might also make a joke about the long line you’re both in\, or comment on the current situation. If you areinterested in learning more about \"small talk\"\, now it’s your chance to sign up for this workshop on how to navigate small talk as an international student. In this workshop\, we will educate you on what is small talk and you will also have the chance to practice small talk with Peers!

SUMMARY:Workshop / Seminar:Probability and Analysis Seminar:  Convergence of Unadjusted Langevin in High Dimensions: Delocalization of Bias
DESCRIPTION:The unadjusted Langevin algorithm is commonly used to sample probability distributions in extremely high-dimensional settings. However\, existing analyses of the algorithm for strongly log-concave distributions suggest that\, as the dimension $d$ of the problem increases\, the number of iterations required to ensure convergence within a desired error in the $W_2$ metric scales in proportion to $d$ or $\sqrt{d}$. In this work\, we argue that\, despite this poor scaling of the $W_2$ error for the full set of variables\,  the behavior for a \emph{small number} of variables can be significantly better: a number of iterations proportional to $K$\, up to logarithmic terms in $d$\, often suffices for the algorithm to converge to within a desired $W_2$ error for all $K$-marginals. We refer to this effect as \textit{delocalization of bias}.  We show that the delocalization effect does not hold universally and prove its validity for Gaussian distributions and strongly log-concave distributions with certain sparse interactions. Our analysis relies on a novel $W_{2\,\ell^\infty}$ metric to measure convergence. A key technical challenge we address is the lack of a one-step contraction property in this metric. Finally\, we use asymptotic arguments to explore potential generalizations of the delocalization effect beyond the Gaussian and sparse interactions setting.
