Deterministic Discrete Denoising
Hideyuki Suzuki, Wataru Kurebayashi, Hiroshi Yamashita
We propose a deterministic denoising algorithm for discrete-state diffusion models. The key idea is to derandomize the generative reverse Markov chain by introducing a variant of t…

Convolutional Formulation of Large-Scale Quadratic Unconstrained Binary Optimization with Dense Interactions
Hiroshi Yamashita, Hideyuki Suzuki
The spatial photonic Ising machine (SPIM) is a promising optical hardware solver for large-scale combinatorial optimization problems with dense interactions. As the SPIM can repres…
