Asymptotics and finite sample bounds for prediction and smoothing in Wright-Fisher hidden Markov models
Luigi M. Malgieri, Filippo Ascolani, Matteo Giordano +1
We study signal prediction and smoothing in hidden Markov models whose latent signal is a multi-type Wright-Fisher diffusion and whose discrete-time observations are categorical. W…
Posterior contraction rates in Sobolev norms and Bayesian derivative estimation for infinite-dimensional exponential families
Emanuele Dolera, Stefano Favaro, Matteo Giordano
We study posterior contraction in positive-order Sobolev norms and Bayesian derivative estimation for infinite-dimensional exponential families. We embed the natural parameter in a…
Dirac mode localization in QCD near the crossover temperature
Matteo Giordano, Tamas G. Kovacs, Ferenc Pittler
We study the localization properties of the low-lying Dirac eigenmodes in QCD near the crossover temperature, using stout-smeared staggered fermions and Symanzik-improved gauge act…
Semiparametric Bernstein-von Mises theorems for reversible diffusions
Matteo Giordano, Kolyan Ray
We establish a general semiparametric Bernstein-von Mises theorem for Bayesian nonparametric priors based on continuous observations in a periodic reversible multidimensional diffu…
On strong posterior contraction rates for Besov-Laplace priors in the white noise model
Emanuele Dolera, Stefano Favaro, Matteo Giordano
In this article, we investigate the problem of estimating a spatially inhomogeneous function and its derivatives in the white noise model using Besov-Laplace priors. We show that s…
Statistical algorithms for low-frequency diffusion data: A PDE approach
Matteo Giordano, Sven Wang
We consider the problem of making nonparametric inference in a class of multi-dimensional diffusions in divergence form, from low-frequency data. Statistical analysis in this setti…
High Energy Bounds on Soft N=4 SYM Amplitudes from AdS/CFT
Matteo Giordano, Robi Peschanski
Using the AdS/CFT correspondence, we study the high-energy behavior of colorless dipole elastic scattering amplitudes in N=4 SYM gauge theory through the Wilson loop correlator for…
