WebHere, we use graph theoretic techniques for clustering amino acid sequences. A similarity graph is defined and clusters in that graph correspond to connected subgraphs. Cluster analysis seeks grouping of amino acid sequences into subsets based on distance or similarity score between pairs of sequences. Our goal is to find disjoint subsets ...
WebMay 1, 2024 · In this paper we present a game-theoretic hypergraph matching algorithm to obtain a large number of true matches efficiently. First, we cast hypergraph matching as a multi-player game and obtain the final matches as an ESS group of candidate matches. In this way we remove false matches and obtain a high matching accuracy, especially with … sideshow bob\u0027s last gleamingWeb2 Clustering 2.1 Graph Theoretic Clustering A clustering of a graph, G =(V,E) consists of a partition V = V 1 ∪ V 2 ∪....∪ V k of the node set of G.
