A Frobenius-Optimal Projection for Enforcing Linear Conservation in Learned Dynamical Models
John M. Mango, Ronald Katende
We consider the problem of restoring linear conservation laws in data-driven linear dynamical models. Given a learned operator and a full-rank constraint matrix e…

Preserving Extreme Singular Values with One Oblivious Sketch
John M. Mango, Ronald Katende
We study when a single linear sketch can control the largest and smallest nonzero singular values of every rank- matrix. Classical oblivious embeddings require $s=Î(r/\varepsil…
