Biography

I am is currently a Visiting Assistant Professor (postdoc) of School of Mathematics and Southeast Center of Mathematics and Biology at Georgia Institute of Technology. My mentor is Dr. Greg Blekherman, and I also collaborate with Dr. Daniel Goldman’s CRAB Lab on the study of animal locomotions.

In the Fall 2020 semester, I am teaching Math 3012 - Applied Combinatorics, which is in hybrid mode.

I was born and raised in Beijing, China. My name in Simplified Chinese is 林博.

Bounding The Number of Linear Regions in Local Area for Neural Networks with ReLU Activations

The number of linear regions is one of the distinct properties of the neural networks using piecewise linear activation functions such …

Tropical Optimal Transport and Wasserstein Distances in Phylogenetic Tree Space

We study the problem of optimal transport on phylogenetic tree space from the perspective of tropical geometry, and thus define the …

Two-player incentive compatible outcome functions are affine maximizers

In mechanism design, for a given type space, there may be incentive compatible outcome functions which are not affine maximizers. We …

Tropical Fermat-Weber Points

In a metric space, the Fermat-Weber points of a sample are statistics to measure the central tendency of the sample and it is well …
