475 | Selecting optimal minimum spanning trees that share a topological correspondence with phylogenetic trees | Choi et. al (2011) introduced a minimum spanning tree (MST)-based method

models, a statistical framework that is commonly used for inferring
phylogenetic trees. While CLGrouping works correctly if there is a unique MST,

476 | Noisy Natural Gradient as Variational Inference | Variational Bayesian neural nets combine the flexibility of deep learning

plane arising from the multigrid method in such a way that these cellular
automata are isomorphic to Conway's Game of Life. Although these tilings are
nonperiodic, determining the next state of each tile is a local computation,

the vicinity of the linear limit, for isotropic or anisotropic
