SUMMARY:Other:Nature Play Pop-Ups
DESCRIPTION:Lightly guided nature play\n\nMatthaei Botanical Gardens is hosting free\, hands-on Nature Play Pop-ups at the Gaffield Children’s Garden. This lightly guided play takes place in the nature art area of the Gaffield Children’s Garden. Young children will have hands-on fun while taking a closer look at nature\, and parents will leave with easy ideas to encourage creative nature play at home. No registration\, free event. First to arrive\, first to play. Kids can join in as spaces open during the pop-ups. Suggested ages 3-7. Please note\, all materials stay at Gaffield Children’s Garden unless otherwise specified.

SUMMARY:Workshop / Seminar:Probability and Analysis Seminar:  Singular perturbations of Hamilton–Jacobi equations in the Wasserstein space
DESCRIPTION:In this talk\, I will present a singular perturbation problem for second-order Hamilton–Jacobi equations\, focusing on the asymptotic behavior of solutions as the perturbation parameter vanishes. The analysis is carried out in the framework of viscosity solutions for equations in the Wasserstein space\, using the perturbed test function method adapted to this infinite-dimensional setting. I will also discuss connections with the homogenization of systems of slow–fast McKean–Vlasov stochastic differential equations.

SUMMARY:Workshop / Seminar:Solving dynamic portfolio selection problems via score-based diffusion models
DESCRIPTION:In this paper\, we tackle the dynamic mean-variance portfolio selection problem in a modelfree manner\, based on (generative) diffusion models. We propose using data sampled from the real model P (which is unknown) with limited size to train a generative model Q (from which we can easily and adequately sample). With adaptive training and sampling methods that are tailor-made for time series data\, we obtain quantification bounds between P and Q in terms of the adapted Wasserstein metric AW 2. Importantly\, the proposed adapted sampling method also facilitates conditional sampling. In the second part of this paper\, we provide the stability of the mean-variance portfolio optimization problems in AW 2. Then\, combined with the error bounds and the stability result\, we propose a policy gradient algorithm based on the generative environment\, in which our innovative adapted sampling method provides approximate scenario generators. We illustrate the performance of our algorithm on both simulated and real data. For real data\, the algorithm based on the generative environment produces portfolios that beat several important baselines\, including the Markowitz portfolio\, the equal weight (naive) portfolio\, and S&P 500.\nJoint work with Erhan Bayraktar and Fengyi Yuan.

SUMMARY:Workshop / Seminar:Student AIM Seminar: An introduction to FMM and its family tree
DESCRIPTION:The Fast Multipole Method (FMM) was dubbed one of the \"Top 10 algorithms\" of the 20th century by SIAM editors\, along with other household names such as the Monte Carlo method\, Quicksort\, and Krylov subspace iterative methods. The FMM addresses the high computation cost for pairwise interactions in specific N-body problems in many areas of physics\, for example electrostatic potentials of charged particles or gravitational forces among stars and galaxies. The problem\, which naively computes O(N^2) pairs of interactions\, can be reduced to O(N) using the multipole expansion as an approximation for far interactions. The method comes with clear error bounds for the approximation and allows for many subsequent extensions. In this talk\, I will walk through the main theorems in Greengard and Rocklin's original paper in 1987[1]\, explain the algorithm\, and give a survey of several generalizations of this algorithm that allows it to be applied to a wide range of problems.\n\n[1] L.

SUMMARY:Workshop / Seminar:Dips with the DPEs
DESCRIPTION:Dips with the DPEs is apart of the How to Flourish (HTF) Workshop that is offered through Trotter Multicultural Center's workshop/ and or programming series. HTF is a series of program or workshops that is based off of the Model of  Wellbeing. Each dimension of wellness focuses on eight areas: physical\, mental\, environmental\, financial\, occupational\, social\, intellectual\, and spiritual. Dips with the DPEs focuses on the environmental wellness dimension. Historically for first-year and first gen students\, this workshop is open to any and everybody.\n\nJoin the Diversity Peer Educators (DPEs) as they stop by the Trotter Multicultural Center to share advice and insights for first-year students on navigating campus life\, building community in the residence halls\, and getting involved with the Multicultural Council. This interactive panel offers attendees the opportunity to ask questions about adjusting to college\, building community\, and accessing supportive campus resources. They’ll also gain helpful tips and guidance for applying to the Diversity Peer Educator role. And of course\, chips and dips will be provided as we “dip” into meaningful conversations about making U-M home!
