Genome-based microorganism classification using coalition formulation game
Summary
We introduce a coalition formation game for efficient microorganism classification using word frequency features. This distributed algorithm achieves classification correctness comparable to centralized methods for large genomic datasets.
Area of Science:
- Bioinformatics
- Computational Biology
- Microbial Taxonomy
Background:
- Genome-based microorganism classification is crucial but challenged by large bio-sequence data from advanced sequencing.
- Existing methods may lack efficiency in processing massive datasets.
Purpose of the Study:
- To propose a low-complexity, distributed algorithm for microorganism classification.
- To leverage coalition formation games for efficient bio-sequence data analysis.
Main Methods:
- Feature extraction using word frequency from microorganism sequences.
- Formulation of a coalition game model incorporating word frequency feature distances.
- Development of a coalition formation algorithm for clustering based on feature similarity.
Main Results:
- The proposed distributed algorithm demonstrates classification correctness similar to conventional centralized schemes.
- Experimental results validate the performance of the coalition formation approach.
Conclusions:
- Coalition formation games offer an effective and efficient distributed approach for genome-based microorganism classification.
- The method is suitable for handling the large-scale data generated by modern sequencing technologies.

01:24Microbial Classification System
1.6K
Classification is the process of organizing organisms into hierarchically inclusive groups based on their phenotypic similarities or evolutionary relationships. A species comprises one or more strains, and closely related species are grouped into genera. Genera are further classified into families, families into orders, orders into classes, and so forth, up to the domain level, which is the broadest taxonomic rank derived from a combination of phenotypic and genotypic data.The nomenclature of...

7.2K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.

The phylogenetic species concept (PSC) is a framework used to delineate species based on evolutionary relationships, emphasizing shared ancestry and diagnosable genetic traits. Unlike morphological or biological species concepts, the PSC is particularly advantageous for microbial taxonomy, where traditional reproductive or phenotypic criteria often fall short due to the prevalence of asexual reproduction, minimal morphological differentiation, and widespread horizontal gene transfer among...
