  • Invited Speaker: HUYNH MANH KHANG (Georgia Institute of Technology, USA)
  • Date & Time: 12nd December 2024, 2024, 09:00 - 11:00.
  • Title:  Optimization of Controlled Sweeping Processes and Neural Networks
  • Room: Room 7.1 Administration Building, Linh Trung Campus.
  • Abstract:  We give a high-level overview of the theory of differential equations, starting from Picard's theorem, leading to applications to Navier-Stokes, and we then discuss possible ideas about the undecidability of blow-ups.

This talk will be accessible for first-year undergrads.

After the seminar, Dr. Huynh Manh Khang will take a few minutes to share his learning journey, from being an undergraduate honors student to achieving his postdoctoral accomplishments.

Seminar Details:

    • Title: Robust Model Averaging Prediction of Longitudinal Response with Ultrahigh-dimensional Covariate
    • Speaker: Professor Dr. Jialiang Li
    • Time: 02:00 PM, Saturday, December 12nd, 2024.
    • Venue: Room C.41, University of Science, VNU-HCM.
      (227 Nguyen Van Cu Street, Ward 4, District 5, Ho Chi Minh City)

Abstract:

Model averaging is an attractive ensemble technique to construct fast and accurate prediction. Despite of having been widely practiced in cross-sectional data analysis, its application to longitudinal data is rather limited so far. We consider model averaging for longitudinal response when the number of covariates is ultrahigh. To this end, we propose a novel two-stage procedure in which variable screening is first conducted and then followed by model averaging. In both stages, a robust rank-based estimation function is introduced to cope with potential outliers and heavy-tailed error distributions, while the longitudinal correlation is modeled by a modified Cholesky decomposition method and properly incorporated to achieve efficiency. Asymptotic properties of our proposed methods are rigorously established, including screening consistency and convergence of the model averaging predictor, with uncertainties in the screening step and selected model set both taken into account. Extensive simulation studies demonstrate that our method outperforms existing competitors, resulting in significant improvements in screening and prediction performance. Finally, we apply our proposed framework to analyze a human microbiome dataset, showing the capability of our procedure in resolving robust prediction using massive metabolites.

Keywords: Robust statistics; Longitudinal model; high-dimensional model
