  • Some New Advances in Similarity-Based Predictive Modeling (Joel A. Dubin, University of Waterloo)

    Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United States

    Abstract: Earlier work has shown that similarity-based predictive models can improve upon predictive performance, as compared to using the entire training data to help build models, particular regarding model discrimination for binary responses. My collaborators and I have some updated results to share, regarding similarity-based modeling for joint consideration of model calibration and discrimination, as […]

  • Singularities in characteristic p and the Riemann–Hilbert correspondence (Robert Cass, CMC)

    Estella 2099

    The Riemann–Hilbert correspondence relates algebra to differential equations on complex algebraic varieties. In characteristic p, there is an analogous correspondence due to Emerton–Kisin and later generalized by Bhatt–Lurie, where the derivative operator is replaced by the p-th power Frobenius operator. In this talk we will explain a relation between the mod p Riemann–Hilbert correspondence and […]

  • Claremont Topology Seminar: Puttipong Pongtanapaisan (Pitzer College)

    Fletcher 104, Pitzer College 1050 N Mills Ave, Claremont, United States

    We welcome all undergraduate/graduate students and faculty to attend topology seminar! Speaker: Puttipong Pongtanapaisan (Pitzer College) Title: Special Positions of Shapes in Four-Dimensional Space Abstract: I will begin by convincing you that four-dimensional space is more familiar than it might first appear. Then, I will introduce ways in which mathematicians study objects in 4-space. Each […]

  • Estimating Shapley Values for Explainable AI via Richer Model Approximations (Teal Witter, CMC)

    Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United States

    Abstract: Modern machine learning is ultimately a simple process: We iteratively update the weights of machine learning models to minimize a problem-specific loss. When it works well, we deploy the model in human-facing domains like healthcare, finance, or the justice system. But even though we know how models are trained, we don't understand why they […]

  • From sparsity of rational points on curves to the generic positivity of Beilinson-Bloch height (Ziyang Gao, UCLA)

    Estella 2099

    It is a fundamental question to find rational solutions to a given system of polynomials, and in modern language this translates into finding rational points in algebraic varieties.  It is already very deep for algebraic curves defined over Q.  An intrinsic natural number associated with the curve, called its genus, plays an important role in […]

  • CCMS Colloquium: Anna Ma (UCI)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by Anna Ma (UCI) Title: Stochastic iterative methods for solving tensor linear systems Abstract: Solving linear systems is a crucial subroutine and challenge in data science and scientific computing. Classical approaches for solving linear systems assume that data is readily available and small enough to be stored in […]

  • GEMS November 1st Session

    Shanahan B450, Harvey Mudd College 301 Platt Blvd., Claremont, United States

    This GEMS session will be facilitated by Grace Akinwande from the Claremont Graduate University. Title: From Pizza to Calculus: Understanding Area Through Approximation Abstract: How much more pizza do you really get from a larger size? In this presentation, we explore the concept of area starting from an everyday question—the pizza dilemma! We’ll review basic […]

  • Convergence analysis of the Alternating Anderson-Picard method for nonlinear fixed-point problems (Xue Feng, UCLA)

    Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United States

    Abstract: Anderson Acceleration (AA) has been widely used to solve nonlinear fixed-point problems due to its rapid convergence. This talk focuses on a variant of AA in which multiple Picard iterations are performed between each AA step, referred to as the Alternating Anderson-Picard (AAP) method. Despite introducing more `slow' Picard iterations, this method has been […]

  • Claremont Topology Seminar: Robert Cass (Claremont McKenna College)

    Fletcher 104, Pitzer College 1050 N Mills Ave, Claremont, United States

    We welcome all undergraduate/graduate students and faculty to attend topology seminar! Speaker: Robert Cass (Claremont McKenna College) Title: Schubert varieties are splinters Abstract: Schubert varieties are among the most well-studied singular algebraic varieties, and they have numerous applications in combinatorics and representation theory. In positive characteristic, Schubert varieties are known to be Frobenius split by […]
