Schedule optimization for tau-leaping in masked discrete diffusion
Cecilia Secchi, Giacomo Zanella
Masked discrete diffusion models are commonly accelerated using the so-called tau-leaping discretization method, which reveals several coordinates in parallel at each sampling step…

Spectral gap of Metropolis-within-Gibbs under log-concavity
Cecilia Secchi, Giacomo Zanella
The Metropolis-within-Gibbs (MwG) algorithm is a widely used Markov chain Monte Carlo method for sampling from high-dimensional distributions when exact conditional sampling is int…
