MATH_PhD Student Seminar - Dynamic community detection for the Global Trading Networks via Tucker Decomposition
Community detection is one of the most important tools in understanding network topology. Even though its methods are initially developed for static networks, the extension to the dynamic case has been widely utilized to analyze the dynamic networks as its prevalence in numerous applications.

MATH_PhD Student Seminar - Eigenvector distribution for spiked model with or without missing condition
In random matrix theory, one of the central topics is the limiting behavior of eigenvalues and eigenvectors of random matrices under fixed-rank perturbations. A famous model, raised by Johnstone, is the so-called spiked covariance matrix model.

MATH_PhD Student Seminar - High-order finite difference gas-kinetic scheme for the Euler and Navier-Stokes equations
With the two-stage fourth-order temporal evolution of the gas distribution function and Weighted Essential Non-Oscillatory (WENO) reconstruction, a high-order finite difference gas-kinetic scheme is proposed.

MATH_PhD Student Seminar - Bidirectional Generative Modeling Using Adversarial Gradient Estimation
We consider the general $f$-divergence formulation of bidirectional generative modeling, which includes VAE and BiGAN as special cases. We present a new optimization method for this formulation, where the gradient is computed using an adversarially learned discriminator.
