Amid the recent surge in next-generation sequencing technologies, alignment-free algorithms stand out as a promising alternative to traditional alignment-based methods in phylogenetic analyses. Specifically, the use of genomic signatures has enabled the success of supervised machine learning-based alignment-free methods in taxonomic classification.

Motivated by this success, this dissertation investigates the potential of unsupervised learning-based alignment-free algorithms in genomic signature categorization and attempts to connect the worlds of biodiversity and taxonomic identification with the world of deep unsupervised learning. Our findings reveal deep learning’s untapped potential to capture taxonomic information, even without supervision. The methodologies presented in this dissertation can also be used to learn expressive DNA embeddings and test evolutionary hypotheses.
