Unsupervised metagenomic clustering aims at partitioning a metagenomic sample into sets that approximate taxonomic units, without using reference genomes. ...
  • A Framework for Space-Efficient String Kernels 

    Belazzougui, Djamal; Cunial, Fabio
    In : (Springer, 2017-02-17)
    String kernels are typically used to compare genome-scale sequences whose length makes alignment impractical, yet their computation is based on data structures that are either space-inefficient, or incur large slowdowns. We show that a number of exact kernels on pairs of strings of total length n, like the k-mer kernel, ...
