Although most of these methods apply MCMC directly, the rate of convergence of MCMC has become a concern as larger and more denselyfactored models are being considered, motivating the need for more efficient sampling that uses parallelism (Singh et al., 2011;Gonzalez et al., 2011) and domain knowledge for blocking (Singh et al., 2010).
we feel providing a method to speed up MCMC inference can have a significant impact.
