Delayed rejection Hamiltonian Monte Carlo for sampling multiscale distributions
Chirag Modi, Alex Barnett, Bob Carpenter
The efficiency of Hamiltonian Monte Carlo (HMC) can suffer when sampling a distribution with a wide range of length scales, because the small step sizes needed for stability in hig…
CosmicRIM : Reconstructing Early Universe by Combining Differentiable Simulations with Recurrent Inference Machines
Chirag Modi, François Lanusse, Uroš Seljak +2
Reconstructing the Gaussian initial conditions at the beginning of the Universe from the survey data in a forward modeling framework is a major challenge in cosmology. This require…
Mind the gap: the power of combining photometric surveys with intensity mapping
Chirag Modi, Martin White, Emanuele Castorina +1
The long wavelength modes lost to bright foregrounds in the interferometric 21-cm surveys can partially be recovered using a forward modeling approach that exploits the non-linear…
