%description
This is a method (MinED) for mining probability distributions using
deterministic sampling which is proposed by Joseph, Wang, Gu, Lv, and Tuo
(2019) <DOI:10.1080/00401706.2018.1552203>. The MinED samples can be used
for approximating the target distribution. They can be generated from a
density function that is known only up to a proportionality constant and
thus, it might find applications in Bayesian computation. Moreover, the
MinED samples are generated with much fewer evaluations of the density
function compared to random sampling-based methods such as MCMC and
therefore, this method will be especially useful when the unnormalized
posterior is expensive or time consuming to evaluate. This research is
supported by a U.S. National Science Foundation grant DMS-1712642.
