Investigating Evaluation Measures in Ant Colony Algorithms for Learning Decision Tree Classifiers [PDF]
, 2015 Ant-Tree-Miner is a decision tree induction algorithm that is based on the Ant Colony Optimization (ACO) meta- heuristic. Ant-Tree-Miner-M is a recently introduced extension of Ant-Tree-Miner that learns multi-tree classification models.

STRING v10: protein–protein interaction networks, integrated over the tree of life
Nucleic Acids Res., 2014 The many functional partnerships and interactions that occur between proteins are at the core of cellular processing and their systematic characterization helps to provide context in molecular systems biology.

Categorizing Ideas about Trees: A Tree of Trees
PLoS ONE, 2013 The aim of this study is to explore whether matrices and MP trees used to produce systematic categories of organisms could be useful to produce categories of ideas in history of science. We study the history of the use of trees in systematics to represent the diversity of life from 1766 to 1991.

Special Matrices, 2019 Considered are combinatorially symmetric matrices, whose graph is a given tree, in view of the fact recent analysis shows that the geometric multiplicity theory for the eigenvalues of such matrices closely parallels that for real symmetric (and complex ...

Lianas Suppress Seedling Growth and Survival of 14 Tree Species in a Panamanian Tropical Forest [PDF]
, 2016 Lianas are a common plant growth form in tropical forests, where they compete intensely with trees, decreasing tree recruitment, growth, and survival. If the detrimental effects of lianas vary significantly with tree species identity, as is often assumed,

Trees with the second-minimal ABC energy
AIMS Mathematics, 2022 The atom-bond connectivity energy (ABC energy) of an undirected graph $ G $, denoted by $ \mathcal{E}_{ABC}(G) $, is defined as the sum of the absolute values of the ABC eigenvalues of $ G $.

Efficient Tree Tensor Network States (TTNS) for Quantum Chemistry: Generalizations of the Density Matrix Renormalization Group Algorithm [PDF]
, 2013 We investigate tree tensor network states for quantum chemistry. Tree tensor network states represent one of the simplest generalizations of matrix product states and the density matrix renormalization group.

Declining object recognition performance in Semantic Dementia - a case for stored visual object representations [PDF]
, 2015 The role of the semantic system in recognising objects is a matter of debate. Connectionist theories argue that it is impossible for a participant to determine that an object is familiar to them without recourse to a semantic hub; localist theories state

Special Matrices, 2019 Given a combinatorially symmetric matrix A whose graph is a tree T and its eigenvalues, edges in T can be classified in four categories, based upon the change in geometric multiplicity of a particular eigenvalue, when the edge is removed.
