Johnson-Lindenstrauss Embeddings with Kronecker Structure

Stefan Bamberger, Felix Krahmer, Rachel Ward

We prove the Johnson-Lindenstrauss property for matrices $Φ D_{ξ}$ where $Φ$ has the restricted isometry property and $D_{ξ}$ is a diagonal matrix containing the entries of a Kronecker…

The Hanson-Wright Inequality for Random Tensors

Stefan Bamberger, Felix Krahmer, Rachel Ward

We provide moment bounds for expressions of the type $(X^{(1)} \otimes \dots \otimes X^{(d)})^{T} A (X^{(1)} \otimes \dots \otimes X^{(d)})$ where $\otimes$ denotes the Kronecker pro…
