Z

Here is my CV. (last updated: Dec 2, 2024)

Bio

Hi! I’m an undergraduate student majoring in mathematics, from the school of gifted young at USTC, my name is Zhi (志), you can simply call me Z. I’m honored to be supervised by Difan Zou (grokking @HKU.), Andrés R. Vindas Meléndez (algebraic combinatorics @Berkeley), and Quan Wen (neuroscience @USTC)!

I’m actively seeking for opportunities to continue my study as a PhD student!

Research Interests

I’m interested in using mathematics to unveil how artificial and biological computational systems learn and generalize, focusing on connectivity in these networks.

• Learning theory, emergent behaviors (e.g. grokking), learning regimes and dynamics, feature learning, and model compression.
• Computational neuroscience, especially the relation between connectivity and activity: the forward problem of predicting neural activity given connectome (e.g. prediction of activity dimension from the low-rank structure of connectome), and the inverse problem of inferring synaptic strength from neural activity recordings and connectome (e.g. via Simulation-Based Inference).

Besides, I’m also generally interested in analysis and optimization.

Publications

Lee Eon, Andrés R. Vindas-Meléndez, and Zhi Wang. Generalized Snake Posets, Order Polytopes, and Lattice-Point Enumeration, 2024, submitted. arxiv:2411.18695.

Currently working on a paper in grokking and low-rank training!
