Law of Large Numbers for continuous -particle ensembles at fixed temperature
Cesar Cuenca, Jiaming Xu
In this paper, we find necessary and sufficient conditions for the Law of Large Numbers of averaged empirical measures of -particle ensembles, in terms of the asymptotics of the…
A Proof of The Changepoint Detection Threshold Conjecture in Preferential Attachment Models
Hang Du, Shuyang Gong, Jiaming Xu
We investigate the problem of detecting and estimating a changepoint in the attachment function of a network evolving according to a preferential attachment model on vertices,…
Airy limit for -additions through Dunkl operators
David Keating, Jiaming Xu
It is well known that the edge limit of Gaussian/Laguerre Beta-ensembles, as well as a large class of -ensembles is given by the point process. We extend this…
Rectangular Matrix Additions in Low and High Temperatures
Jiaming Xu
We study the addition of two independent random rectangular matrices with invariant distributions in two limiting regimes, where the parameter (inverse temperature)…

Wen Chen, Pipei Huang, Jiaming Xu +7
Increasing demand for fashion recommendation raises a lot of challenges for online shopping platforms and fashion communities. In particular, there exist two requirements for fashi…
Rates of Convergence of Spectral Methods for Graphon Estimation
Jiaming Xu
This paper studies the problem of estimating the grahpon model - the underlying generating mechanism of a network. Graphon estimation arises in many applications such as predicting…
