One-step lowest-variance selection in a Gaussian random-field model motivated by masked diffusion: Total correlation and a square root collision threshold
Linjun Li
Motivated by confidence-guided parallel unmasking in masked discrete diffusion, we study a single selection step in a stylized Gaussian random-field model. A locally dependent nonn…

On Support Cardinality for the Discrete Schrödinger Equation
Linjun Li
How sparse can a nontrivial solution of a discrete Schrödinger equation be? In this note we study Dirichlet solutions on a finite -dimensional lattice box, allowing an arbitrar…
