Sharp spectral norm concentration and regularization of sparse random tensors
Zhixin Zhou, Yizhe Zhu
We prove sharp spectral-norm bounds and construct a mean-fitting regularization procedure for sparse random tensors of fixed order . For an tensor with i…

Proximity Graph Maintenance for Fast Online Nearest Neighbor Search
Zhaozhuo Xu, Weijie Zhao, Shulong Tan +2
Approximate Nearest Neighbor (ANN) search is a fundamental technique for (e.g.,) the deployment of recommender systems. Recent studies bring proximity graph-based methods into prac…

Sparse random tensors: Concentration, regularization and applications
Zhixin Zhou, Yizhe Zhu
We prove a non-asymptotic concentration inequality for the spectral norm of sparse inhomogeneous random tensors with Bernoulli entries. For an order- inhomogeneous random tensor…
