A non-backtracking method for long matrix and tensor completion
Ludovic Stephan, Yizhe Zhu
We consider the problem of low-rank rectangular matrix completion in the regime where the matrix of size is ``long", i.e., the aspect ratio diverges to infini…
Overparameterized random feature regression with nearly orthogonal data
Zhichao Wang, Yizhe Zhu
We investigate the properties of random feature ridge regression (RFRR) given by a two-layer neural network with random Gaussian initialization. We study the non-asymptotic behavio…
Partial recovery and weak consistency in the non-uniform hypergraph Stochastic Block Model
Ioana Dumitriu, Hai-Xiao Wang, Yizhe Zhu
We consider the community detection problem in sparse random hypergraphs under the non-uniform hypergraph stochastic block model (HSBM), a general model of random networks with com…
Deformed semicircle law and concentration of nonlinear random matrices for ultra-wide neural networks
Zhichao Wang, Yizhe Zhu
In this paper, we investigate a two-layer fully connected neural network of the form , where $X\in\mathbb{R}^{d_0\tim…
