Definition Clustering can be considered the most important unsupervised learning technique; so, as every other problem of this kind, it deals with finding a structure in a collection of unlabeled data. Clustering is “the process of organizing objects into groups whose members are similar in some ...

Genomes of lower organisms have been observed with a large amount of horizontal gene transfers, which cause difficulties in their evolutionary study. Bacteriophage genomes are a typical example. One recent approach that addresses this problem is the unsu

These data demonstrate a lack of complete correlation between the class systems and that the possible plasticity seen suggests that outlier cases may have intermediate characteristics and may represent distinct clinical entities. It will be important to determine if our unsupervised gene expression–based...
