SUMMARY:Workshop / Seminar:Exploratory Optimal Reinsurance under the Mean-Variance Criterion
DESCRIPTION:This paper proposes a Reinforcement Learning (RL) approach to the optimal reinsurance problem\nwhen the insurer faces uncertainty about the insurance claim dynamics. To this end\, we first formulate\nan exploratory version of the problem as a relaxed stochastic control problem. Within a broad class of\nparametric retention functions and general risk loading functions\, we derive the closed-form equilibrium\npolicy under the continuous-time mean-variance criterion. This is achieved through a formal verification\ntheorem and solving classical solutions of a system of exploratory extended Hamilton-Jacobi-Bellman\n(EEHJB) equations. We then establish a policy iteration theorem\, showing that starting from any timeand state-homogeneous policy\, policy iteration converges to the derived equilibrium policy. Next\, we\ndevelop a martingale orthogonality theorem\, which serves as the foundation of our RL algorithm. The\nalgorithm is evaluated through simulation studies and real data from the U.S. National Flood Insurance\nProgram. Results demonstrate that the RL approach effectively learns unknown claim distributions\,\ntracks unobserved changes in claim dynamics and produces higher insurer surplus trajectories than the\nmaximum likelihood estimation (MLE) approach while simultaneously exhibiting greater robustness to\nthe choice of training window.

SUMMARY:Well-being:Hacking College Life With Chronic Illness and/or Disability
DESCRIPTION:Our 6-week wellness coaching group is a supportive space for U-M students with disabilities or chronic health conditions. It’s a chance to connect with others\, share experiences\, and support one another. \n\nDates/times: We will meet on Wednesdays from 4-5 p.m. on Zoom.\n\nWe will cover the following topics:\n\nSession 1: November 4 — Intros\, Agreements\, Ground Rules\, and Definitions\nSession 2: November 11 — Boundaries and Values\nSession 3: November 18 — Addressing Worry\nNOTE: No group on Wednesday\, November 25\, due to proximity to Thanksgiving\nSession 4: December 2 — Self-Compassion Mindset\nSession 5: December 9 — Time Management\nSession 6: December 16 — Wrap Up\, Review\, and Optional Future Connections \nPlease note: the group can decide whether to wrap up a week earlier\, given the end of the semester.\nLocation: Zoom\; link sent upon completion of online intake/screening. \n\nSign up: Register through our online scheduler. Please select “Group Coaching” when selecting your coaching type\, and you will be shown the calendar for current groups. Just sign up for the first session. If you attend\, we will add you to future sessions. No additional participants will be added after the first session.

SUMMARY:Workshop / Seminar:Probability and Analysis: Strongly log-concave measures and lattices
DESCRIPTION:Let L be a lattice in R^n. Suppose that L has the property that the determinant of every non-zero sublattice L' of L is larger than one. We prove that there exists a symmetric random vector X on R^n with a smooth\, strictly positive density f on R^n simultaneously enjoying the following two properties: a) f is strongly log-concave\; b) X + L is uniform on R^n/L.\n\nMoreover\, the existence of such a density f on R^n characterizes this determinant condition imposed on L. This construction connects several problems in lattice theory to established results in convex geometry. We discuss a range of applications. This is joint work with Victor Reis and Thomas Rothvoss.
