SUMMARY:Workshop / Seminar:Student Analysis Seminar: Signal detection in the spiked Wigner matrix model
DESCRIPTION:In this talk\, we consider a spiked matrix model of the form: signal plus Wigner noise. The spectral properties of this model have been extensively studied\, and a spectral threshold has been identified: above this threshold\, the largest eigenvalue contains information about the signal\, while below it\, the eigenvalue is uninformative. We then examine a class of signals for which a phase transition in the statistical test for the presence of a signal occurs strictly before this spectral threshold. An introduction to the fundamentals of hypothesis testing and spin glass theory will also be provided.

SUMMARY:Performance:Earth Day Concert
DESCRIPTION:Students in the studio of Tiffany Ng perform on the Charles Baird Carillon\, an instrument of 53 bronze bells located inside the Burton Memorial Tower. The largest bell\, which strikes the hour\, weighs 12 tons\, while the smallest bell\, 4½ octaves above\, weighs just 15 pounds.\n\nThirty-minute recitals are performed on the Charles Baird Carillon at noon every weekday that classes are in session\, followed by visitor Q&A with the carillonist. The bell chamber may be accessed via a combination of elevator and stairs. Take the elevator to the highest floor possible (floor 8)\, and then climb two flights of stairs (39 steps) to the bell chamber (floor 10). Hearing protection earmuffs are provided for visitors. Be prepared to walk on ice and snow in the bell chamber during winter. Built in 1936\, the Charles Baird Carillon is not ADA accessible. Visitors with mobility concerns are invited to visit the Lurie Carillon.
