Directed acyclic graph kernels for structural RNA analysis

open access: yesBMC 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 ...

Directed Acyclic Outerplanar Graphs Have Constant Stack Number [PDF]

open access: yesTheoretiCS
The 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 ...

On compact directed acyclic word graphs [PDF]

open access: yes, 1997
The Directed Acyclic Word Graph (DAWG) is a space-efficient data structure to treat and analyze repetitions in a text, especially in DNA genomic sequences. Here, we consider the Compact Directed Acyclic Word Graph of a word. We give the first direct algorithm to construct it. It runs in time linear in the length of the string on a fixed alphabet.

Causal Structure Learning With One-Dimensional Convolutional Neural Networks

open access: yesIEEE 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 ...
