Accurate Data-Driven Surrogates of Dynamical Systems for Forward Propagation of Uncertainty

no code implementations16 Oct 2023 Saibal De, Reese E. Jones, Hemanth Kolla

Stochastic collocation (SC) is a well-known non-intrusive method of constructing surrogate models for uncertainty quantification.

Continuous-variable neural-network quantum states and the quantum rotor model

1 code implementation15 Jul 2021 James Stokes, Saibal De, Shravan Veerapaneni, Giuseppe Carleo

We initiate the study of neural-network quantum state algorithms for analyzing continuous-variable lattice quantum systems in first quantization.

Efficient MCMC Sampling for Bayesian Matrix Factorization by Breaking Posterior Symmetries

no code implementations8 Jun 2020 Saibal De, Hadi Salehi, Alex Gorodetsky

This choice of prior leads to simple implementations; however it also causes symmetries in the posterior distribution that can severely reduce the efficiency of Markov-chain Monte-Carlo (MCMC) sampling approaches.
