Figure 2

Three MAP inference methods – a comparison. The plot illustrates the fact that optimization over the full r × t parameter space (red curves) is much slower than both the equivalent optimization over l with subsequent DP-partition of l into r and t (blue curves), and the method combining r × t search with occasional DP-optimization interruptions (green curves). The solid curves show log-likelihoods including the priors p [r]p [t|T], whereas the dashed curves show the same results, but excluding that factor. Approximate point of convergence, i.e., the first point when 1000 subsequent steps has not resulted in any improvement, is marked with an asterisk.
