Graphlets and motifs in biological networks
WebJan 28, 2024 · Typed graphlets are a powerful generalization of the notion of graphlet (network motif) to heterogeneous networks as they capture both the induced subgraph of interest and the types associated with the nodes in the induced subgraph. To address this problem, we propose a fast, parallel, and space-efficient framework for counting typed … WebDec 7, 2024 · Pedro Ribeiro and Fernando Silva. 2014. Discovering colored network motifs.

Graphlet degree vectors (signatures) and signature similarities were applied to biological networks to identify groups (or clusters) of topologically similar nodes in a network and predict biological properties of yet uncharacterized nodes based on known biological properties of characterized nodes. See more Graphlets in mathematics are induced subgraph isomorphism classes in a graph, i.e. two graphlet occurrences are isomorphic, whereas two graphlets are non-isomorphic. Graphlets differ from network motifs in … See more RGF-distance and GDD-agreement were used to evaluate the fit of various network models to real-world networks and to discover a new, well-fitting, geometric random graph model for protein-protein interaction networks, as well as other types of See more Relative graphlet frequency distance RGF-distance compares the frequencies of the appearance of all 3-5-node graphlets in two networks.

WebMotifs. Network motifs are repeated graphlets (small subgraphs of a larger network that appear at any frequency) in a specific network capturing particular patterns of interactions between vertices. They are often associated with particular functions (Stone et al., 2024) and are used for many applications in biological networks (Kim et al ... WebJun 27, 2016 · From social science to biology, numerous applications often rely on graphlets for intuitive and meaningful characterization of networks. While graphlets have witnessed a tremendous success and impact in a variety of domains, there has yet to be a fast and efficient framework for computing the frequencies of these subgraph patterns. …
WebJun 15, 2015 · Our new notion of dynamic graphlets is different from existing dynamic network approaches that are based on temporal motifs (statistically significant subgraphs). The latter have limitations: their results depend on the choice of a null network model that is required to evaluate the significance of a subgraph, and choosing a good null model is ...
