Unbiased Low-Rank Approximation for Repeated Matrix-Vector Multiplication: Stability and Optimal Sampling
Replacing the matrix in an iteration with random low-rank matrices can reduce the cost of matrix-vector multiplication.Proofs of strong forms of the Bovdi--Geche universality conjecture and a complex analogue
We prove two universality theorems for neural networks consisting of a single neuron.Fast factorization in diagram monoids
We give explicit algorithms that factor elements of the standard diagram monoids into their usual generators.A 27 x 27 x 27 counterexample to Comon's conjecture
We report an explicit construction of a 27 x 27 x 27 symmetric tensor with rational entries that has tensor rank 55 over the rational numbers and symmetric tensor rank 56 over the complex numbers…Bi-Oriented Interlaced Matrix Multiplication and an Operator Factorisation of the Quantum Harmonic Oscillator
We introduce a bi-oriented interlaced matrix product on $2\times 2$ matrices over a unital, possibly non-associative algebra, extending a matrix mnemonic for Cayley--Dickson doubling.
