The Covering Threshold of a Directed Acyclic Graph by Directed Acyclic Subgraphs
The Electronic Journal of Combinatorics, 2022 Let $H$ be a directed acyclic graph (dag) that is not a rooted star. It is known that there are constants $c=c(H)$ and $C=C(H)$ such that the following holds for $D_n$, the complete directed graph on $n$ vertices. There is a set of at most $C\log n$ directed acyclic subgraphs of $D_n$ that covers every $H$-copy of $D_n$, while every set of at most $c ...

Directed acyclic graph kernels for structural RNA analysis
BMC Bioinformatics, 2008 Background Recent discoveries of a large variety of important roles for non-coding RNAs (ncRNAs) have been reported by numerous researchers. In order to analyze ncRNAs by kernel methods including support vector machines, we propose stem kernels as an ...

Attractors of directed graph IFSs that are not standard IFS attractors and their Hausdorff measure [PDF]
, 2012 "GCB was supported by an EPSRC Doctoral Training Grant whilst undertaking this work"For directed graph iterated function systems (IFSs) defined on R, we prove that a class of 2-vertex directed graph IFSs have attractors that cannot be the attractors of ...

Directed Acyclic Outerplanar Graphs Have Constant Stack Number [PDF]
TheoretiCSThe stack number of a directed acyclic graph $G$ is the minimum $k$ for which there is a topological ordering of $G$ and a $k$-coloring of the edges such that no two edges of the same color cross, i.e., have alternating endpoints along the topological ...

Causal Structure Learning With One-Dimensional Convolutional Neural Networks
IEEE Access, 2021 Causal structure discovery has an important guiding role in explanatory artificial intelligence. In order to discover causal relationships from observed data and restore causal structure graphs, we propose the Directed Acyclic Graph structure learning ...
