MATH_PhD Student Seminar - Mathematical Ranking Frameworks and Application Perspectives in Blockchain and Decentralized Finance Space
The seminar presents mathematical ranking theories (PageRank, HodgeRank) and their practical algorithms in various application scenarios. The presenter also provides a literature review on static learning approach for the ranking problem. His study on the area is clearly discussed, e.g.

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.

MATH_PhD Student Seminar - Local behavior of positive solutions of higher order conformally invariant equations with a singular set
We study some properties of singular positive solutions to the conformally invariant equations. We prove an asymptotic blow rate estimate for positive solutions near the singular set with some conditions about the Minkowski dimension of the set.

MATH_PhD Student Seminar - Black-Box Adversarial Attack
Current neural network-based classifiers are susceptible to adversarial examples even in the black-box setting, where the attacker could only query the output of the network. We present a new method for black-box adversarial attack.
