# Variational Inference (VI)
#
# This script demonstrates how MGVI
and
GeoVI
work for an inference problem
# with only two real quantities of interest. This
enables us to plot the
# posterior probability density as two-dimensional plot.
The approximate
# posterior samples are contrasted with the maximum-a-posterior
(MAP) solution
# together with samples drawn with the Laplace method. This
method uses the
# local curvature at the MAP solution as inverse covariance of
a Gaussian
# probability density.
