Network Cross-Validation for Determining the Number of Communities in Network Data
Kehui Chen, Jing Lei
The stochastic block model and its variants have been a popular tool in analyzing large network data with community structures. In this paper we develop an efficient network cross-…
The functional mean-shift algorithm for mode hunting and clustering in infinite dimensions
Mattia Ciollaro, Christopher Genovese, Jing Lei +1
We introduce the functional mean-shift algorithm, an iterative algorithm for estimating the local modes of a surrogate density from functional data. We show that the algorithm can…
Functional Regression for Quasar Spectra
Mattia Ciollaro, Jessi Cisewski, Peter Freeman +4
The Lyman-alpha forest is a portion of the observed light spectrum of distant galactic nuclei which allows us to probe remote regions of the Universe that are otherwise inaccessibl…
